Accounting Policies [Abstract]
Basis of Presentation	Note 1— Basis of Presentation In these notes, Cray Inc. and its wholly-owned subsidiaries are collectively referred to as the “Company.” In the opinion of management, the accompanying Condensed Consolidated Balance Sheets, Statements of Operations, Statements of Comprehensive Income (Loss), and Statements of Cash Flows have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. Management believes that all adjustments (consisting of normal recurring adjustments) considered necessary for fair presentation have been included. Interim results are not necessarily indicative of results for a full year. The information included in this Form 10-Q should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the financial statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2015 . The Company’s revenue, results of operations and cash balances are likely to fluctuate significantly from quarter to quarter. These fluctuations are due to such factors as the high average sales prices and limited number of sales of the Company’s products, the timing of purchase orders and product deliveries, the revenue recognition accounting policy of generally not recognizing product revenue until customer acceptance and other contractual provisions have been fulfilled and the timing of payments for product sales, maintenance services, government research and development funding and purchases of inventory. Given the nature of the Company’s business, its revenue, receivables and other related accounts are likely to be concentrated among a relatively small number of customers. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Cray Inc. and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Revenue Recognition The Company recognizes revenue, including transactions under sales-type leases, when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when it has persuasive evidence of an arrangement, delivery has occurred, the sales price is fixed or determinable, and collectibility is reasonably assured. Delivery does not occur until the products have been shipped or services provided to the customer, risk of loss has transferred to the customer, and, where applicable, a customer acceptance has been obtained. The sales price is not considered to be fixed or determinable until all material contingencies related to the sales have been resolved. The Company records revenue in the Condensed Consolidated Statements of Operations net of any sales, use, value added or certain excise taxes imposed by governmental authorities on specific sales transactions. In addition to the aforementioned general policy, the following are the Company’s statements of policy with regard to multiple-element arrangements and specific revenue recognition policies for each major category of revenue. Multiple-Element Arrangements. The Company commonly enters into revenue arrangements that include multiple deliverables of its product and service offerings due to the needs of its customers. Products may be delivered in phases over time periods which can be as long as five years . Maintenance services generally begin upon acceptance of the first equipment delivery and future deliveries of equipment generally have an associated maintenance period. The Company considers the maintenance period to commence upon acceptance of the product or installation in situations where a formal acceptance is not required, which may include a warranty period and accordingly allocates a portion of the arrangement consideration as a separate deliverable which is recognized as service revenue over the entire service period. Other services such as training and engineering services can be delivered as a discrete delivery or over the term of the contract. A multiple-element arrangement is separated into more than one unit of accounting if the following criteria are met: • The delivered item(s) has value to the customer on a standalone basis; and • If the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. If these criteria are met for each element, the arrangement consideration is allocated to the separate units of accounting based on each unit’s relative selling price. If these criteria are not met, the arrangement is accounted for as one unit of accounting which would result in revenue being recognized ratably over the contract term or being deferred until the earlier of when such criteria are met or when the last undelivered element is delivered. The Company follows a selling price hierarchy in determining the best estimate of the selling price of each deliverable. Certain products and services are sold separately in standalone arrangements for which the Company is sometimes able to determine vendor specific objective evidence, or VSOE. The Company determines VSOE based on normal pricing and discounting practices for the product or service when sold separately. When the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements, the Company attempts to establish the selling price of each remaining element based on third-party evidence, or TPE. The Company’s inability to establish VSOE is often due to a relatively small sample of customer contracts that differ in system size and contract terms which can be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history, such as in the case of certain advanced and emerging technologies. TPE is determined based on the Company’s prices or competitor prices for similar deliverables when sold separately. However, the Company is often unable to determine TPE, as the Company’s offerings usually contain a significant level of customization and differentiation from those of competitors and the Company is often unable to reliably determine what similar competitor products’ selling prices are on a standalone basis. When the Company is unable to establish selling price using VSOE or TPE, the Company uses estimated selling price, or ESP, in its allocation of arrangement consideration. The objective of ESP is to determine the price at which the Company would transact a sale if the product or service were sold on a standalone basis. In determining ESP, the Company uses the cost to provide the product or service plus a margin, or considers other factors. When using cost plus a margin, the Company considers the total cost of the product or service, including customer-specific and geographic factors. The Company also considers the historical margins of the product or service on previous contracts and several factors including any changes to pricing methodologies, competitiveness of products and services and cost drivers that would cause future margins to differ from historical margins. Products . The Company most often recognizes revenue from sales of products upon customer acceptance of the system. Where formal acceptance is not required, the Company recognizes revenue upon delivery or installation. When the product is part of a multiple element arrangement, the Company allocates a portion of the arrangement consideration to product revenue based on estimates of selling price. Services . Maintenance services are provided under separate maintenance contracts with customers. These contracts generally provide for maintenance services for one year , although some are for multi-year periods, often with prepayments for the term of the contract. The Company considers the maintenance period to commence upon acceptance of the product, or installation of the product where a formal acceptance is not required, which may include a warranty period. When service is part of a multiple element arrangement, the Company allocates a portion of the arrangement consideration to maintenance service revenue based on estimates of selling price. Maintenance contracts that are billed in advance of revenue recognition are recorded as deferred revenue. Maintenance revenue is recognized ratably over the term of the maintenance contract. Revenue from engineering services is recognized as services are performed. Project Revenue . Revenue from design and build contracts is recognized under the percentage-of-completion, or POC, method. Under the POC method, revenue is recognized based on the costs incurred to date as a percentage of the total estimated costs to fulfill the contract. If circumstances arise that change the original estimates of revenues, costs, or extent of progress toward completion, revisions to the estimates are made. These revisions may result in increases or decreases in estimated revenues or costs, and such revisions are recorded in income in the period in which the circumstances that gave rise to the revision become known by management. The Company performs ongoing profitability analyses of its contracts accounted for under the POC method in order to determine whether the latest estimates of revenue, costs and extent of progress require updating. If at any time these estimates indicate that the contract will be unprofitable, the entire estimated loss for the remainder of the contract is recorded immediately. The Company records revenue from certain research and development contracts which include milestones using the milestone method if the milestones are determined to be substantive. A milestone is considered to be substantive if management believes there is substantive uncertainty that it will be achieved and the milestone consideration meets all of the following criteria: • It is commensurate with either of the following: • The Company’s performance to achieve the milestone; or • The enhancement of value of the delivered item or items as a result of a specific outcome resulting from the Company’s performance to achieve the milestone. • It relates solely to past performance. • It is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. The individual milestones are determined to be substantive or non-substantive in their entirety and milestone consideration is not bifurcated. Revenue from projects is classified as Product Revenue or Service Revenue, based on the nature of the work performed. Nonmonetary Transactions . The Company values and records nonmonetary transactions at the fair value of the asset surrendered unless the fair value of the asset received is more clearly evident, in which case the fair value of the asset received is used.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	Note 2— New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. Adoption of ASU 2014-09 was initially required for fiscal and interim reporting periods beginning after December 15, 2016 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. In August 2015, FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date: Topic 606 (ASU 2015-14) that deferred the effective date of ASU 2014-09 by one year. Application of the new revenue standard is permitted for fiscal and interim reporting periods beginning after December 15, 2016 and required for fiscal and interim reporting periods beginning after December 15, 2017. The Company is currently evaluating the potential impact of the pending adoption of ASU 2014-09 on its consolidated financial statements. In July 2015, FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory: Topic 330 (ASU 2015-11). Topic 330 currently requires an entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. ASU 2015-11 requires that inventory measured using either the FIFO or average cost method be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Adoption of ASU 2015-11 is required for fiscal reporting periods beginning after December 15, 2016, including interim reporting periods within those fiscal years. The Company does not expect the adoption of ASU 2015-11 to have a material impact on its consolidated financial statements. In November 2015, FASB issued Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes: Topic 740 (ASU 2015-17). Current GAAP requires the deferred taxes for each jurisdiction to be presented as a net current asset or liability and net noncurrent asset or liability. This requires a jurisdiction-by-jurisdiction analysis based on the classification of the assets and liabilities to which the underlying temporary differences relate, or, in the case of loss or credit carryforwards, based on the period in which the attribute is expected to be realized. Any valuation allowance is then required to be allocated on a pro rata basis, by jurisdiction, between current and noncurrent deferred tax assets. The new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. The guidance does not change the existing requirement that only permits offsetting within a jurisdiction. Adoption of ASU 2015-17 is required for fiscal reporting periods beginning after December 15, 2016, including interim reporting periods within those fiscal years, and either prospective or retrospective application is permitted. Early adoption of ASU 2015-17 is permitted. At the time of adoption, all of the Company’s deferred tax assets and liabilities, along with any related valuation allowance, will be classified as noncurrent on its Consolidated Balance Sheet. Currently, the Company does not plan to early-adopt ASU 2015-17. In January 2016, FASB issued Accounting Standards Update No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities: Topic 825 (ASU 2016-01). The updated guidance enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. Adoption of ASU 2016-01 is required for fiscal reporting periods beginning after December 15, 2017, including interim reporting periods within those fiscal years. The Company is currently evaluating the potential impact of the pending adoption of ASU 2016-01 on its consolidated financial statements. In February 2016, FASB issued Accounting Standards Update No. 2016-02, Leases: Topic 842 (ASU 2016-02) that replaces existing lease guidance. The new standard is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. Under the new guidance, leases will continue to be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statement of Operations. Lessor accounting is largely unchanged under ASU 2016-02. Adoption of ASU 2016-02 is required for fiscal reporting periods beginning after December 15, 2018, including interim reporting periods within those fiscal years with early adoption being permitted. The new standard is required to be applied with a modified retrospective approach to each prior reporting period presented with various optional practical expedients. The Company is currently evaluating the potential impact of the pending adoption of ASU 2016-02 on its consolidated financial statements. In March 2016, FASB issued Accounting Standards Update No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09). The updated guidance simplifies and changes how companies account for certain aspects of share-based payment awards to employees, including accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of certain items in the statement of cash flows. Adoption of ASU 2016-09 is required for fiscal reporting periods beginning after December 15, 2016, including interim reporting periods within those fiscal years with early adoption being permitted. The Company early-adopted ASU 2016-09 in the first quarter of 2016. At the time of adoption, the Company recognized $16.6 million in deferred tax assets for all excess tax benefits that had not been previously recognized because the related tax deduction had not reduced taxes payable. This was accomplished through a cumulative-effect adjustment to accumulated deficit. All excess tax benefits and all tax deficiencies generated in the current and future periods will be recorded as income tax benefit or expense in the Company’s Consolidated Statement of Operations in the reporting period in which they occur. This will result in increased volatility in the Company’s effective tax rate. The Company has determined that none of the other provisions of ASU 2016-09 will have a significant impact on its consolidated financial statements. The table below shows the accumulated deficit activity for the six months ended June 30, 2016 (in thousands): Accumulated Deficit BALANCE, December 31, 2015 $ (125,411 ) Purchase of employee restricted shares to fund related statutory tax withholding (696 ) Cumulative-effect adjustment resulting from adoption of ASU 2016-09 16,600 Net Loss (18,139 ) BALANCE, June 30, 2016 $ (127,646 )

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	Note 3— Fair Value Measurement Based on the observability of the inputs used in the valuation techniques used to determine the fair value of certain financial assets and liabilities, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The following table presents information about the Company’s financial assets and liabilities that have been measured at fair value as of June 30, 2016 , and indicates the fair value hierarchy of the valuation inputs utilized to determine such fair value (in thousands): Description Fair Value Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Assets: Cash and cash equivalents and restricted cash $ 214,400 $ 214,400 $ — Available-for-sale investments (1) 9,318 9,318 — Foreign currency exchange contracts (2) 17,727 — 17,727 Assets measured at fair value at June 30, 2016 $ 241,445 $ 223,718 $ 17,727 Liabilities: Foreign currency exchange contracts (3) 1,478 — 1,478 Liabilities measured at fair value at June 30, 2016 $ 1,478 $ — $ 1,478 (1) Included in “Short-term investments” on the Company’s Condensed Consolidated Balance Sheets. (2) Included in “Prepaid expenses and other current assets” and “Other non-current assets” on the Company’s Condensed Consolidated Balance Sheets. (3) Included in “Other accrued liabilities” and “Other non-current liabilities” on the Company’s Condensed Consolidated Balance Sheets. Foreign Currency Derivatives The Company may enter into foreign currency derivatives to hedge future cash receipts on certain sales transactions that are payable in foreign currencies.

Earnings Per Share [Abstract]
Loss Per Share (EPS)	Note 5— Income (Loss) Per Share ("EPS") Basic EPS is computed by dividing net income (loss) available to common shareholders by the weighted average number of common shares, excluding unvested restricted stock, outstanding during the period. Diluted EPS is computed by dividing net income (loss) available to common shareholders by the weighted average number of common and potential common shares outstanding during the period, which includes the additional dilution related to conversion of stock options, unvested restricted stock and unvested restricted stock units as computed under the treasury stock method. For the three and six months ended June 30, 2016 and the six months ended June 30, 2015 , outstanding stock options, unvested restricted stock and unvested restricted stock units were antidilutive because of the net losses and, as such, their effect has not been included in the calculation of basic or diluted net loss per share. For the three months ended June 30, 2015 , the added shares from these items included in the calculation of diluted shares and EPS totaled 1.7 million . For the three and six months ended June 30, 2016 , potential gross common shares of 2.8 million and 2.8 million , respectively, were antidilutive and not included in computing diluted EPS. For the three and six months ended June 30, 2015 , potential gross common shares of 0.9 million and 3.1 million , respectively, were antidilutive and not included in computing diluted EPS. An additional 1.2 million and 1.4 million performance vesting restricted stock and performance vesting restricted stock units were excluded from the computation of potential common shares for the three and six months ended June 30, 2016 and 2015 , respectively, because the conditions for vesting had not been met as of the balance sheet date.

Leases [Abstract]
Sales-type lease	Note 8— Sales-type Lease The Company has a sales-type lease with one of its customers. Under the terms of the original agreement, the Company provided a high performance computing solution to the customer for a term of four years, beginning at the customer’s acceptance of the system. In the three months ended June 30, 2016, the Company delivered a second high performance computing solution and extended the original agreement, which will now end in September 2020. The lease extension, and delivery of the second high performance computing solution, has been accounted for as a separate sale and is not considered a lease modification. The lease is designated in British Pounds and the Company has entered into certain foreign currency exchange contracts that act as an economic hedge for the foreign currency exposure associated with this arrangement. The following table shows the components of the net investment in the sales-type lease as of June 30, 2016 and December 31, 2015 (in thousands): June 30, December 31, 2015 Total minimum lease payments to be received $ 62,583 $ 36,863 Less: executory costs (12,994 ) (7,434 ) Net minimum lease payments receivable 49,589 29,429 Less: unearned income (3,232 ) (1,108 ) Net investment in sales-type lease 46,357 28,321 Less: long-term investment in sales-type lease (37,189 ) (18,317 ) Investment in sales-type lease included in accounts and other receivables $ 9,168 $ 10,004 As of June 30, 2016 , minimum lease payments for each of the succeeding five fiscal years are as follows (in thousands): 2016 (less than 1 year) $ 6,474 2017 14,698 2018 14,888 2019 15,165 2020 11,358 Total minimum lease payments to be received $ 62,583

Contingencies	Note 11— Contingencies A customer has recently experienced significant reliability issues with a high-value third party component in its Cray system after several years of use. We incurred $500,000 in expense related to this matter in the three months ended June 30, 2016, which was recorded as Cost of Service Revenue. The Company is working with the principal customer impacted and vendor to develop an effective solution. While it is possible the Company could incur a material loss under its multi-year service arrangement, management believes the ultimate cost will likely not be material. The Company is currently unable to estimate an amount or range of loss because this matter involves significant uncertainties.

Share-Based Compensation

Share-Based Compensation	6 Months Ended

Share-based Compensation [Abstract]
Share-Based Compensation	Note 12— Share-Based Compensation The Company accounts for its share-based compensation based on an estimate of fair value of the grant on the date of grant. In determining the fair value of stock options, the Company uses the Black-Scholes option pricing model. The following key weighted average assumptions were employed in the calculation for the three and six month periods ended June 30, 2016 and June 30, 2015 : Three Months Ended June 30, 2016 Three Months Ended June 30, 2015 Six Months Ended June 30, 2016 Six Months Ended June 30, 2015 Risk-free interest rate 1.20% 1.29% 1.19% 1.30% Expected dividend yield —% —% —% —% Volatility 50.74% 50.66% 50.82% 50.66% Expected life 4.0 years 4.0 years 4.0 years 4.0 years Weighted average Black-Scholes value of options granted $13.11 $11.38 $13.46 $11.49 The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company does not anticipate declaring dividends in the foreseeable future. Volatility is based on historical data. The expected life of an option is based on the assumption that options will be exercised, on average, about two years after vesting occurs. The Company recognizes compensation expense for only the portion of options that are expected to vest. Therefore, management applies an estimated forfeiture rate that is derived from historical employee termination data and adjusted for expected future employee turnover rates. The estimated forfeiture rate applied to the Company’s stock option grants during the three and six months ended June 30, 2016 and 2015 was 8.0% . If the actual number of forfeitures differs from those estimated by management, additional adjustments to compensation expense may be required in future periods. The Company’s stock price volatility, option lives and expected forfeiture rates involve management’s best estimates at the time of such determination, which impact the fair value of the option calculated under the Black-Scholes methodology and, ultimately, the expense that will be recognized over the vesting period or requisite service period of the option. The Company typically issues stock options with a four year vesting period (the requisite service period) and amortizes the fair value of stock options (stock compensation cost) ratably over the requisite service period. A summary of the Company’s year-to-date stock option activity and related information follows: Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term Outstanding at December 31, 2015 1,948,475 $ 14.83 Grants 163,500 $ 33.37 Exercises (140,545 ) $ 13.24 Canceled and forfeited (22,576 ) $ 26.04 Outstanding at June 30, 2016 1,948,854 $ 16.37 6.1 Exercisable at June 30, 2016 1,393,239 $ 11.91 5.1 Available for grant at June 30, 2016 3,747,568 As of June 30, 2016 , there was $27.0 million of aggregate intrinsic value of outstanding stock options, including $25.3 million of aggregate intrinsic value of exercisable stock options. Intrinsic value represents the total pretax intrinsic value for all “in-the-money” options ( i.e. , the difference between the Company’s closing stock price on the last trading day of its second quarter of 2016 and the exercise price, multiplied by the number of shares of common stock underlying the stock options) that would have been received by the option holders had all option holders exercised their options on June 30, 2016 . During the three and six months ended June 30, 2016 , stock options covering 18,218 and 140,545 shares of common stock, respectively, with a total intrinsic value of $0.2 million and $3.7 million , respectively, were exercised. During the three and six months ended June 30, 2015 , stock options covering 48,613 and 107,620 shares of common stock, respectively, with a total intrinsic value of $0.9 million and $2.6 million , respectively, were exercised. The fair value of unvested restricted stock and unvested restricted stock units is based on the market price of a share of the Company’s common stock on the date of grant and is amortized over the vesting period. A summary of the Company’s unvested restricted stock grants and changes during the six months ended June 30, 2016 is as follows: Service Vesting Restricted Shares Performance Vesting Restricted Shares Total Restricted Shares Shares Weighted Average Grant Date Fair Value Shares Weighted Shares Weighted Average Grant Date Fair Value Outstanding at December 31, 2015 516,443 $ 24.12 585,500 $ 15.07 1,101,943 $ 19.31 Granted 9,893 $ 34.86 — $ — 9,893 $ 34.86 Forfeited (17,325 ) $ 24.64 (57,000 ) $ 15.02 (74,325 ) $ 17.26 Vested (68,352 ) $ 28.55 — $ — (68,352 ) $ 28.55 Outstanding at June 30, 2016 440,659 $ 23.66 528,500 $ 15.08 969,159 $ 18.98 The estimated forfeiture rate applied to the Company’s service vesting restricted share grants during the three and six months ended June 30, 2016 and 2015 , was 8% . The aggregate fair value of restricted stock vested during the three and six months ended June 30, 2016 , was $2.2 million and $2.4 million , respectively. The aggregate fair value of restricted stock vested during the three and six months ended June 30, 2015 , was $2.6 million and $3.1 million , respectively. The performance vesting restricted shares are subject to performance measures that are currently not considered “probable” of attainment and as such, no compensation cost has been recorded for these shares. The performance vesting restricted shares are eligible to vest in 2016 and 2017 . A summary of the Company’s unvested restricted stock unit grants and changes during the six months ended June 30, 2016 is as follows: Service Vesting Restricted Stock Units Performance Vesting Restricted Stock Units Total Restricted Stock Units Units Weighted Average Grant Date Fair Value Units Weighted Units Weighted Average Grant Date Fair Value Outstanding at December 31, 2015 273,050 $ 29.75 632,700 $ 30.04 905,750 $ 29.95 Granted 149,000 $ 32.18 23,585 $ 42.65 172,585 $ 33.61 Forfeited (6,000 ) $ 30.27 — $ — (6,000 ) $ 30.27 Vested (37,000 ) $ 31.02 — $ — (37,000 ) $ 31.02 Outstanding at June 30, 2016 379,050 $ 30.57 656,285 $ 30.49 1,035,335 $ 30.52 The estimated forfeiture rate applied to the Company’s service vesting restricted stock unit grants during the three and six months ended June 30, 2016 and 2015 , was 8.0% . The aggregate fair value of restricted stock vested during the three and six months ended June 30, 2016 , was $1.2 million . Restricted stock units are not outstanding shares and do not have any voting or dividend rights. At the time of vesting, a share of common stock representing each restricted stock unit vested will be issued by the Company. The performance vesting restricted stock units are subject to performance measures that are currently not considered “probable” of attainment and as such, no compensation cost has been recorded for these units. The performance vesting restricted stock units are eligible to vest between 2017 and 2020 . Including performance-based equity awards, the Company had $45.8 million of total unrecognized compensation cost related to unvested stock options, unvested restricted stock and unvested restricted stock units as of June 30, 2016 . Excluding the $28.0 million of unrecognized compensation cost related to unvested restricted stock and unvested restricted stock units that are subject to performance measures that are currently not considered “probable” of attainment, unrecognized compensation cost is $17.8 million . No compensation expense is recognized for unvested restricted stock or unvested restricted stock units subject to performance measures that are not considered “probable” of attainment. Unrecognized compensation cost related to unvested stock options and unvested non-performance-based restricted stock is expected to be recognized over a weighted average period of 2.7 years. The following table sets forth the gross share-based compensation cost resulting from stock options, unvested restricted stock and unvested restricted stock units that were recorded in the Company’s Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2016 and 2015 (in thousands): Three Months Ended Six Months Ended 2016 2015 2016 2015 Cost of product revenue $ 83 $ 78 $ 165 $ 148 Cost of service revenue 68 73 136 139 Research and development, net 582 978 1,531 1,851 Sales and marketing 872 514 1,707 1,452 General and administrative 1,190 1,111 2,108 2,337 Total $ 2,795 $ 2,754 $ 5,647 $ 5,927 The Company also has an employee stock purchase plan, or ESPP, which allows employees to purchase shares of the Company’s common stock at 95% of fair market value on the fourth business day after the end of each offering period. The ESPP is deemed non-compensatory and therefore is not subject to the fair value provisions.

Taxes	Note 13— Taxes The Company’s effective tax rates for the three and six months ended June 30, 2016 and 2015 were as follows: Three Months Ended Six Months Ended 2016 2015 2016 2015 Effective Tax Rates 15% 41% 26% 39% The primary reason for the difference between the expected statutory tax rate of 35% and the actual tax rates of 15% and 26% for the three and six months ended June 30, 2016 , was a a reduction in the Company’s business outlook with respect to the current year which substantially increased the impact that the Company’s research and development tax credit had on its effective tax rate. Other significant reconciling items that impacted the Company’s effective tax rate included excess tax benefits, and state and foreign taxes. Prior to the adoption of ASU 2016-09 excess tax benefits did not impact the Company’s effective tax rate. The primary reason for the difference between the expected statutory tax rate of 35% and the actual tax rates of 41% and 39% for the three and six months ended June 30, 2015 was the result of state taxes. The Company continues to provide a valuation allowance against specific U.S. deferred tax assets and a valuation allowance against deferred tax assets arising in a limited number of foreign jurisdictions as the realization of such assets is not considered to be more likely than not at this time. No changes were required to previously recorded valuation allowances as a result of the adoption of ASU 2016-09. In a future period the Company’s assessment of the realizability of its deferred tax assets and therefore the appropriateness of the valuation allowance could change based on an assessment of all available evidence, both positive and negative in that future period. If the Company’s conclusion about the realizability of its deferred tax assets and therefore the appropriateness of the valuation allowance changes in a future period it could record a substantial tax provision or benefit in the Condensed Consolidated Statement of Operations when that occurs.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Cray Inc. and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.
Revenue Recognition	Revenue Recognition The Company recognizes revenue, including transactions under sales-type leases, when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when it has persuasive evidence of an arrangement, delivery has occurred, the sales price is fixed or determinable, and collectibility is reasonably assured. Delivery does not occur until the products have been shipped or services provided to the customer, risk of loss has transferred to the customer, and, where applicable, a customer acceptance has been obtained. The sales price is not considered to be fixed or determinable until all material contingencies related to the sales have been resolved. The Company records revenue in the Condensed Consolidated Statements of Operations net of any sales, use, value added or certain excise taxes imposed by governmental authorities on specific sales transactions. In addition to the aforementioned general policy, the following are the Company’s statements of policy with regard to multiple-element arrangements and specific revenue recognition policies for each major category of revenue. Multiple-Element Arrangements. The Company commonly enters into revenue arrangements that include multiple deliverables of its product and service offerings due to the needs of its customers. Products may be delivered in phases over time periods which can be as long as five years . Maintenance services generally begin upon acceptance of the first equipment delivery and future deliveries of equipment generally have an associated maintenance period. The Company considers the maintenance period to commence upon acceptance of the product or installation in situations where a formal acceptance is not required, which may include a warranty period and accordingly allocates a portion of the arrangement consideration as a separate deliverable which is recognized as service revenue over the entire service period. Other services such as training and engineering services can be delivered as a discrete delivery or over the term of the contract. A multiple-element arrangement is separated into more than one unit of accounting if the following criteria are met: • The delivered item(s) has value to the customer on a standalone basis; and • If the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. If these criteria are met for each element, the arrangement consideration is allocated to the separate units of accounting based on each unit’s relative selling price. If these criteria are not met, the arrangement is accounted for as one unit of accounting which would result in revenue being recognized ratably over the contract term or being deferred until the earlier of when such criteria are met or when the last undelivered element is delivered. The Company follows a selling price hierarchy in determining the best estimate of the selling price of each deliverable. Certain products and services are sold separately in standalone arrangements for which the Company is sometimes able to determine vendor specific objective evidence, or VSOE. The Company determines VSOE based on normal pricing and discounting practices for the product or service when sold separately. When the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements, the Company attempts to establish the selling price of each remaining element based on third-party evidence, or TPE. The Company’s inability to establish VSOE is often due to a relatively small sample of customer contracts that differ in system size and contract terms which can be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history, such as in the case of certain advanced and emerging technologies. TPE is determined based on the Company’s prices or competitor prices for similar deliverables when sold separately. However, the Company is often unable to determine TPE, as the Company’s offerings usually contain a significant level of customization and differentiation from those of competitors and the Company is often unable to reliably determine what similar competitor products’ selling prices are on a standalone basis. When the Company is unable to establish selling price using VSOE or TPE, the Company uses estimated selling price, or ESP, in its allocation of arrangement consideration. The objective of ESP is to determine the price at which the Company would transact a sale if the product or service were sold on a standalone basis. In determining ESP, the Company uses the cost to provide the product or service plus a margin, or considers other factors. When using cost plus a margin, the Company considers the total cost of the product or service, including customer-specific and geographic factors. The Company also considers the historical margins of the product or service on previous contracts and several factors including any changes to pricing methodologies, competitiveness of products and services and cost drivers that would cause future margins to differ from historical margins. Products . The Company most often recognizes revenue from sales of products upon customer acceptance of the system. Where formal acceptance is not required, the Company recognizes revenue upon delivery or installation. When the product is part of a multiple element arrangement, the Company allocates a portion of the arrangement consideration to product revenue based on estimates of selling price. Services . Maintenance services are provided under separate maintenance contracts with customers. These contracts generally provide for maintenance services for one year , although some are for multi-year periods, often with prepayments for the term of the contract. The Company considers the maintenance period to commence upon acceptance of the product, or installation of the product where a formal acceptance is not required, which may include a warranty period. When service is part of a multiple element arrangement, the Company allocates a portion of the arrangement consideration to maintenance service revenue based on estimates of selling price. Maintenance contracts that are billed in advance of revenue recognition are recorded as deferred revenue. Maintenance revenue is recognized ratably over the term of the maintenance contract. Revenue from engineering services is recognized as services are performed. Project Revenue . Revenue from design and build contracts is recognized under the percentage-of-completion, or POC, method. Under the POC method, revenue is recognized based on the costs incurred to date as a percentage of the total estimated costs to fulfill the contract. If circumstances arise that change the original estimates of revenues, costs, or extent of progress toward completion, revisions to the estimates are made. These revisions may result in increases or decreases in estimated revenues or costs, and such revisions are recorded in income in the period in which the circumstances that gave rise to the revision become known by management. The Company performs ongoing profitability analyses of its contracts accounted for under the POC method in order to determine whether the latest estimates of revenue, costs and extent of progress require updating. If at any time these estimates indicate that the contract will be unprofitable, the entire estimated loss for the remainder of the contract is recorded immediately. The Company records revenue from certain research and development contracts which include milestones using the milestone method if the milestones are determined to be substantive. A milestone is considered to be substantive if management believes there is substantive uncertainty that it will be achieved and the milestone consideration meets all of the following criteria: • It is commensurate with either of the following: • The Company’s performance to achieve the milestone; or • The enhancement of value of the delivered item or items as a result of a specific outcome resulting from the Company’s performance to achieve the milestone. • It relates solely to past performance. • It is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. The individual milestones are determined to be substantive or non-substantive in their entirety and milestone consideration is not bifurcated. Revenue from projects is classified as Product Revenue or Service Revenue, based on the nature of the work performed. Nonmonetary Transactions . The Company values and records nonmonetary transactions at the fair value of the asset surrendered unless the fair value of the asset received is more clearly evident, in which case the fair value of the asset received is used
Investments	The Company’s investments in debt securities with maturities at purchase greater than three months are classified as “available-for-sale.” Changes in fair value are reflected in other comprehensive income (loss).
