PGI

PGI compilers incorporate optimization, vectorization, software pipelining, and shared-memory parallelization capabilities.

A partial list of technical features supported includes the following:

PGF95 native OpenMP and auto-parallel Fortran 90/95 compiler
PGF77 native OpenMP and auto-parallel FORTRAN 77 compiler
PGHPF native data parallel compiler with full HPF language support (Linux only)
PGCC OpenMP and auto-parallel ANSI and K&R C compiler
PGC++OpenMP and auto-parallel C++ compiler
PGDBGOpenMP parallel graphical debugger
PGPROFOpenMP parallel graphical performance profiler
Full 64-bit support on multi-core AMD Opteron, Athlon 64 and Turion, and Intel Pentium and Xeon with EM64T
AMD Opteron and Intel EM64T optimizations including SSE/SSE2/SSE3/SSSE3, SSE4a/ABM, prefetching, use of extended register sets, and 64-bit addressing
Intel Pentium II/III/4/Xeon and AMD Athlon XP/MP optimizations including SSE/SSE2 and prefetching where supported in hardware
PGI Unified Binary? combines into a single executable file code optimized for multiple AMD64 and EM64T processors
Complete uniform development environment across 64-bit and 32-bit systems based on either AMD or Intel processors running Linux, Mac OS X or Windows
Large file (> 2GB) support in Fortran on 32-bit x86 systems
