Optimization for Intel® Architectures


In Episode 5 of the “Hands-On Workshop (HOW) series on parallel programming and optimization with Intel® architectures”, we begin the discussion of performance optimization. This episode lays out the optimization roadmap that classifies optimization techniques into five categories of optimization.

The lecture part of the episode demonstrates the application of some of the techniques from these 5 categories to an example application implementing the N-body simulation. The video also provides references to additional case studies in which optimization is demonstrated.

The hands-on part of the episode demonstrates the optimization process for the N-body simulation and measures performance gains obtained on an Intel® Xeon® E5 processor and an Intel® Xeon Phi™ coprocessor of the first generation.



英特尔的编译器针对非英特尔微处理器的优化程度可能与英特尔微处理器相同(或不同)。这些优化包括 SSE2、SSE3 和 SSSE3 指令集和其他优化。对于在非英特尔制造的微处理器上进行的优化,英特尔不对相应的可用性、功能或有效性提供担保。该产品中依赖于微处理器的优化仅适用于英特尔微处理器。某些非特定于英特尔微架构的优化保留用于英特尔微处理器。关于此通知涵盖的特定指令集的更多信息,请参阅适用产品的用户指南和参考指南。
