Parallel Fortran, C and C++ Compilers and tools for 32-bit and 64-bit AMD64 and IA32 Processor-based Linux Servers

PGI Server-class compilers and tools are for 32-bit x86 (AMD* AthlonXP*, Intel* Pentium* 4 and Xeon*), 64-bit AMD64 technology (AMD Opteron*) and 64-bit IA32 EM64T (Intel Xeon-64) processors processor-based servers with up to 16 CPU or threads running Linux/x86 operating systems.

The PGI Server compilers and OpenMP Linux debugger/profiler allow multiple users to compile, debug and profile on any compatible computer networked to the system on which the PGI compilers are installed (a network-floating license). Debugging and profiling are constrained to at most 16 processors or threads. Executables are constrained to use at most 16 processors/threads, and can be executed on any compatible system regardless of whether the PGI compilers are installed.

Outstanding single-processor performance, uncommon reliability, support for most common extensions, and automatic or user-directed parallelization for shared-memory parallel systems add up to compilers that "just work" for users migrating from RISC/UNIX workstations and servers to 32-bit or 64-bit processor-based systems.

PGI is currently shipping Release 5.2 of these compilers and tools, with support for auto-parallelization and OpenMP or HPF user-directed parallelization on Linux. Release 5.2 includes a major update to both the PGDBG ® OpenMP Linux graphical debugger and the PGPROF OpenMP Linux performance profiler.
