PGI的编译器将直接为AMD FireStream流处理器

PGI的编译器将直接为AMD FireStream流处理器和X86+GPU混合处理器生成代码.PGI声称它在工业界首次推出一项新技术, 程序员只需在原有程序中添加几个编译指示,编译器便可从相关段落生成加速器专用代码.http://www.pgroup.com/about/news.htm#32 The Portland Group and AMD Ink Agreement to Collaborate onAccelerator Compiler TechnologyAustin, TXNovember 18, 2008Cooperation based around PGI's x64+GPU compiler technology and AMD FireStream™ compute accelerators with an eye toward AMD FusionThe Portland Group®, a wholly-owned subsidiary of STMicroelectronics and leading supplier of compilers for high-performance computing (HPC), today announced it has entered into an agreement with AMD to cooperate on the development of compiler technology for AMD FireStream™ compute accelerators. As part of the agreement, PGI and AMD will investigate and develop technology to enable PGI® Fortran and C compilers to generate code directly for AMD FireStream boards and to generate heterogeneous x64+GPU (Graphics Processing Unit) executables that enable automatic utilization of AMD FireStream products if present in a system.The Portland Group recently delivered a technology preview of the industry's first standard Fortran and C compilers that automatically offload computations from an x64 host program to a GPU. Until now, C and C++ developers targeting GPU accelerators have had to rely on language extensions or library-based solutions, and use of GPUs from Fortran applications has been extremely limited. The PGI x64+GPU programming model enables programmers to accelerate applications simply by adding portable compiler directives, treated as comments by other compilers, to existing standard-compliant Fortran and C programs and recompiling with appropriate compiler options. This gives individual developers the power to incrementally use accelerator technology where appropriate in large existing applications, eliminating the need for expensive and difficult corporate-level platform migration or acquisition decisions."Until now, industry CIO's and government and university lab directors have encountered difficult decisions when evaluating accelerator technologies," said Douglas Miles, director, The Portland Group. "Which accelerators do I choose? How do I retrain developers to use accelerators? How much will I have to invest in new software technologies? Working together with AMD, we will work to make FireStream compute accelerators easily accessible to mainstream C and Fortran developers and unlock the power of these devices using PGI compilers that are already in use at most of the significant HPC centers and sites.""We applaud The Portland Group for giving developers advanced, yet simplified tools for fast, easy creation of GPU accelerated applications," said Patricia Harrell, director of Stream Computing at AMD. "The Portland Group clearly understands the needs of today’s HPC developers, and their efforts are instrumental in driving GPU compute acceleration into the mainstream. We look forward to working with PGI to help ensure their Fortran and C compilers can take full advantage of the over 1.2 teraFLOPS of single-precision, and over 240 gigaFLOPS of double-precision performance capabilities of the AMD FireStream 9270 compute accelerators."PGI develops and markets high-performance C/C++ and Fortran compilers and development tools that are widely used by engineers and scientists in high-performance computing (HPC), the field of technical computing engaged in the modeling and simulation of complex processes, such as ocean modeling, weather forecasting, seismic analysis, bioinformatics and other areas. PGI compilers and tools are designed to extract maximum performance from the latest multi-core x64 processors, including the recently announced 45 nanometer Quad-Core AMD Opteron™ processors from AMD. PGI compilers are recognized in the HPC community for delivering world-class performance across a wide spectrum of applications and benchmarks, and they are referenced regularly as the industry standard for performance and reliability.Key advantages of PGI compilers and tools can be found on The Portland Group web site at www.pgroup.com/about/why_PGI.htm . A free 15-day evaluation of PGI Workstation compilers and tools is available for download at www.pgroup.com/support/downloads.php. Registration is required.
