PGI Compiler

PGI 簡介:

美國PGI公司在Vincent J. Schuster帶領下開發出不少出色的高速Fortran編譯軟體,其中還包括i860,Spare ,Mentor Graphics 等硬體。PGI編譯軟體是Linux玩家大力推薦的Fortran編譯軟體。Linux 專業雜誌測試的Fortran 軟體中,PGI Fortran 編譯軟體所產生執行碼的平均執行速度優於其他編譯軟體高達40%以上。 PGI公司的編譯軟體結合最佳化、向量化、pipeline 模式及Shared-memory 等技術。提供開發人員完整的平行的平行語言發展環境。適用平台涵蓋Intel、AMD 架構及Intel i860,Spare ,Fujitsu microVP 等,適用於F77,C/C++,F90 及HPF 等語言。
