PORTLAND, Ore., The Portland Group(TM) Compiler Technology team of STMicroelectronics (NYSE:STM) today announced the availability of a Beta Release of the PGI(R) Workstation 5.0 Fortran and C compilers for AMD Opteron(TM) processors. This is the first publicly available release of STMicroelectronics' upcoming suite of optimizing software development tools for AMD 64-bit technology processors. The PGI Workstation compilers and tools are used by scientists and engineers to solve some of the world's most challenging technical computing problems in weather modeling, geophysical processing, aerodynamic simulation and related fields. STMicroelectronics will begin commercial shipments of these compilers and tools in June, 2003. The PGI Workstation 5.0 Beta release includes the PGF77(R), PGF90(R), PGCC(R) and PGC++(TM) compilers that take advantage of the 64-bit processing capabilities of AMD Opteron processors. This includes the ability to operate on data sets that are too large for 32-bit X86-compatible processors. The compilers also take advantage of the expanded register sets and processor features of the AMD Opteron to enable more efficient execution of compute-intensive applications. "PGI Workstation 5.0 will help simplify customers' migrations to the power of 64-bit computing on AMD Opteron processor-based servers," said Marty Seyer, vice president of server business segment, Computation Products Group, AMD. "Customers will also be able to optimize 32-bit application performance running on either a 32- or 64-bit operating system, protecting existing investment in their technology infrastructure." The PGI Workstation toolset for AMD Opteron servers and workstations includes all of the capabilities that have made STMicroelectronics' Portland Group Compiler Technology team an industry leader in compilers and tools for high-performance computing: state-of-the art scalar optimizations, automatic parallelization for shared-memory multi-processors, industry standard OpenMP user-directed parallelization, backward-compatibility with legacy compilers and tools, and a reputation for producing compilers and tools suitable for use in the most demanding production computing environments. The production release in June, 2003 will include all of the compilers as well as the PGDBG(R) parallel application debugger and PGPROF(R) parallel application performance profiler. "Porting our software, which represents well over a half million lines of code, from 32-bit X86 processor-based systems to 64-bit AMD Opteron processor-based systems has been very straightforward," said Douglas Miles, director of Portland Laboratory, Advanced Systems Technology, STMicroelectronics. "We have also been extremely impressed with the performance of both legacy 32-bit applications and 64-bit applications re-compiled to take advantage of the new features of the AMD Opteron processor." The Portland Group Compiler Technology compilers and tools products are developed at the AST Portland Laboratory in Portland, Oregon. The PGI Workstation 5.0 Beta 64-bit toolset represents the first important outcome of the cooperation between AMD and The Portland Group(TM) Compiler Technology team of STMicroelectronics announced in September, 2002. It is available for download at http://www.pgroup.com/AMD64. This toolset will be updated to include PGI Workstation 5.0 Beta 32-bit compilers, optimized for execution on Opteron and 32-bit X86 processors, on April 14, 2003.
