摘要 标题 –英特尔助力软件发开人员

摘要 – 在英特尔,我们强烈主张要为软件开发人员提供大力支持。我们在设计我们的处理器、新指令、行业互动以及工具时都秉承着一个宗旨,那就是充分考虑软件开发人员的需求。James将介绍我们在努力为软件开发人员“做正确的事情”时所面临的挑战,并探讨标准和伪标准、支持开源、以更加简便的方式为难以设计的硬件进行编程、软件抽象化、新工具技术,并讲授一些有关并行编程方面的知识。 个人简历 - James Reinders,英特尔并行编程推广总监

James参与了多项工程、研发和培训工作,以推动并行编程技术在整个行业的应用。他于1989年加入英特尔公司,为多个项目作出了杰

出的贡献,包括世界上第一台每秒万亿次浮点计算的超级计算机(ASCI Red),以及世界上第一台每秒万亿次浮点计算的微处理器(英特尔®至强融核™协处理器)。James撰写了多本技术书籍,包括《VTune™ Performance Analyzer Esssentials》 (英特尔出版社,2005年)、《Intel® Threading Building Blocks》(O‘Reilly Media,2007年)、《Structured Parallel Programming》(Morgan Kaufmann,2012年)以及《Intel® Xeon Phi™ Coprocessor High Performance Programming》(Morgan Kaufmann,2013年)。

不存在可以解决所有问题的标准,行业标准是 佳的发展道路

3

标准提供了 佳的选择,并获得了 广泛的支持(大量供应商)。 英特尔力争成为各种标准的 佳支持者,以便满足您的业务需求。 我们重点关注真正的标准,帮助延⻓长代码的使用寿命(包括您现有的代码,以及您将要编写的代码),并且提供出类拔萃的工具来支持真正的标准。

真正的标准

4

•  欢迎供应商和用户参与规范的制定及审批工作;真正独立的标准化流程。 •  标准的目的在于真正为多种硬件和软件环境的软件开发人员提供帮助。 •  不受制于一家供应商(反例:OpenACC、C++ AMP、HAS) •  并非专門设计为针对一家供应商而优化(反例同上)

真正的标准

目前出现了一些令人不安的趋势,伪标准和真正的标准混淆在一起,它们对一种平

台是有用的,受到一家供应商的大力吹捧(CUDA、OpenACC、C++ AMP、HAS)。 甚至还开展了大量的市场活动来推广这些伪标准,使其与真正的标准混淆在一起。

我们可以为软件开发人员提供更好的支持。我们支持真正的标准。 C、C++、Fortran、OpenMP、MPI、OpenCL等。 我们鼓励您多提要求,并推动采用真正的标准来编程。 在这方面还需要做大量的工作。 英特尔认为对所有人来说,这都是一条正确的发展道路。
