5 Programming Resources Intel® Xeon Phi Coprocessor Developers Quick Start GuideQuick Start Guide Overview of Programming for Intel® Xeon® processors and Intel® Xeon Phi coprocessors Overview of Programming Access to webinar replays and over 50 training videoswebinar replaystraining videos Beginning labs for the Intel® Xeon Phi Coprocessor Beginning labs Programming guides, tools, case studies, labs, code samples, forums & moreguidestoolscase studieslabs code samplesforums Click on tabs Existing applications need to be tuned and recompiled to maximize throughput, but you wont need to rethink the entire problem or master new tools and programming models. Even better, applications that run on one processor family will run on the other, and parallel optimizations will maximize performance on both. 5

9 Optimization Notice 9 Intel ® compilers, associated libraries and associated development tools may include or utilize options that optimize for instruction sets that are available in both Intel ® and non-Intel microprocessors (for example SIMD instruction sets), but do not optimize equally for non-Intel microprocessors. In addition, certain compiler options for Intel compilers, including some that are not specific to Intel micro-architecture, are reserved for Intel microprocessors. For a detailed description of Intel compiler options, including the instruction sets and specific microprocessors they implicate, please refer to the Intel ® Compiler User and Reference Guides under Compiler Options." Many library routines that are part of Intel ® compiler products are more highly optimized for Intel microprocessors than for other microprocessors. While the compilers and libraries in Intel ® compiler products offer optimizations for both Intel and Intel- compatible microprocessors, depending on the options you select, your code and other factors, you likely will get extra performance on Intel microprocessors. Intel ® compilers, associated libraries and associated development tools may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include Intel ® Streaming SIMD Extensions 2 (Intel ® SSE2), Intel ® Streaming SIMD Extensions 3 (Intel ® SSE3), and Supplemental Streaming SIMD Extensions 3 (Intel ® SSSE3) instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. While Intel believes our compilers and libraries are excellent choices to assist in obtaining the best performance on Intel ® and non-Intel microprocessors, Intel recommends that you evaluate other compilers and libraries to determine which best meet your requirements. We hope to win your business by striving to offer the best performance of any compiler or library; please let us know if you find we do not.

11 Disclaimers (continued) Usage Guidance Performance tests and ratings are measured using specific computer systems and/or components and reflect the approximate performance of Intel products as measured by those tests. Any difference in system hardware or software design or configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of systems or components they are considering purchasing. For more information on performance tests and on the performance of Intel products, go to: Intel does not control or audit the design or implementation of third party benchmarks or web sites referenced in this document. Intel encourages all of its customers to visit the referenced web sites or others where similar performance benchmarks are reported and confirm whether the referenced benchmarks are accurate and reflect performance of systems available for purchase. Relative performance is calculated by assigning a baseline value of 1.0 to one benchmark result, and then dividing the actual benchmark result for the baseline platform into each of the specific benchmark results of each of the other platforms, and assigning them a relative performance number that correlates with the performance improvements reported. SPEC, SPECint, SPECfp, SPECrate. SPECpower, SPECjAppServer, SPECjEnterprise, SPECjbb, SPECompM, SPECompL, and SPEC MPI are trademarks of the Standard Performance Evaluation Corporation. See for more information. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor series, not across different processor sequences. See for details. Intel products are not intended for use in medical, life saving, life sustaining, critical control or safety systems, or in nuclear facility applications. All dates and products specified are for planning purposes only and are subject to change without notice. 11
