united states area served worldwide products compilers debuggers profilers ides website pgroup.com the portland group inc. or pgi was a company that produced a set of commercially available fortran c and c compilers for high performance computing systems . on july 29 2013 nvidia corporation acquired the portland group inc. 1 the portland group or pgi name is now known as a brand of software development tools produced by nvidia corporation . contents 1 company history 2 product and market history 2.1 compilers 2.2 programming tools 2.3 pgi milestones 3 see also 4 references 5 external links company history edit the portland group was founded as a privately held company in 1989 using compiler technology developed at and acquired from floating point systems inc. the first products pipelining fortran and c compilers were released in 1991 targeting the intel i860 processor . these compilers were used on intel supercomputers like the ipsc 860 the touchstone delta and the paragon and were the compilers of choice for the majority of i860 based platforms . in the early 1990s pgi was deeply involved in the development of high performance fortran or hpf a data parallel language extension to fortran 90 which provides a portable programming interface for a wide variety of architectures . pgi produced an hpf compiler which continues to be available today . in 1996 pgi developed x86 compilers for the asci red supercomputer at sandia national laboratories 2 the first computer system to sustain teraflop performance . in 1997 pgi released x86 compilers for general use on linux workstations . the portland group was acquired by stmicroelectronics in december 2000 3 and operated as a wholly owned subsidiary producing hpc compilers and tools for linux windows and mac os . nvidia corporation acquired pgi from stmicroelectronics on july 29 2013 . 4 today the same compilers and tools are made available through nvidia under the portland group compilers and tools brand name . 5 pgi has been deeply involved in the expansion of the use of gpgpus for high performance computing developing cuda fortran 6 7 with nvidia corporation and pgi accelerator fortran and c compilers 8 which use programming directives . pgi has more recently participated in the specification of the new standard openacc directives for gpu computing and has released a compiler for the opencl language on multi core arm processors . product and market history edit compilers edit pgi compilers incorporate global optimization vectorization software pipelining and shared memory parallelization capabilities targeting both intel and amd processors . pgi supports the following high level languages fortran 77 fortran 90 95 2003 fortran 2008 partial high performance fortran hpf ansi c99 with k & r extensions ansi iso c cuda fortran opencl openacc openmp programming tools edit pgi also provides a parallel debugger pgdbg and a performance profiler pgprof both of which support openmp and mpi parallelism on linux windows and mac os . on windows the pgi fortran compiler and debugger have been fully integrated into microsoft visual studio as a product called pgi visual fortran . pgi
