資料介紹

一整套並行Fortran，C 和C++的編譯器和工具。PGI Workstation 可以運行於基於Intel處理器的工作站、服務器並且運行諸如Linux、Solaris86和NT的操作系統，支持HPF/F90/F77/C/C+ +，支持的語言之多，效能優化之美妙，足以讓每一個使用的用戶拍手稱是。PGI Workstation編譯器以及工具主要用於科學和工程應用，所解決的也都是最具難度的問題和工作，例如天氣建模、地球物理處理、空氣動力學模擬及相關領域。卓越的單處理器性能，非凡的可靠性，支持大多數常見擴展名，對共享內存並行系統進行自動或用戶定向的並行處理，這些構成了為用戶“量身定做”的編譯器用於將 RISC/UNIX 工作站和服務器移植到基於 32 位 x86 或 64 位 x64 處理器運行 Linux 或 Windows 系統。

PGI 服務器包含 PGI 高性能編譯器與 PGDBG OpenMP 並行圖像調試器和 PGPROF OpenMP 並行圖像性能分析器。而且，它允許多個用戶在連接到裝有 PGI 編譯器 (網絡浮動許可) 系統的任何網絡兼容計算機上進行編譯，調試和分析。調試和分析僅限於至多 16 個多核處理器。PGI 服務器生成的可執行程序限制 OpenMP 或自動並行程序使用的線程數。該數字最大值等於發起執行的處理器內核數的 16 倍。可執行程序能在任何兼容的系統上執行，無論是否安裝了 PGI 編譯器。
