PGI工作站编译器和工具

一整套并行Fortran，C 和C++的编译器和工具。PGI Workstation 可以运行于基于Intel处理器的工作站、服务器并且运行诸如Linux、Solaris86和NT的操作系统，支持HPF/F90/F77/C/C+ +，支持的语言之多，效能优化之美妙，足以让每一个使用的用户拍手称是。PGI Workstation编译器以及工具主要用于科学和工程应用，所解决的也都是最具难度的问题和工作，例如天气建模、地球物理处理、空气动力学模拟及相关领域。卓越的单处理器性能，非凡的可靠性，支持大多数常见扩展名，对共享内存并行系统进行自动或用户定向的并行处理，这些构成了为用户“量身定做”的编译器用于将 RISC/UNIX 工作站和服务器移植到基于 32 位 x86 或 64 位 x64 处理器运行 Linux 或 Windows 系统。

PGI 服务器包含 PGI 高性能编译器与 PGDBG OpenMP 并行图像调试器和 PGPROF OpenMP 并行图像性能分析器。而且，它允许多个用户在连接到装有 PGI 编译器 (网络浮动许可) 系统的任何网络兼容计算机上进行编译，调试和分析。调试和分析仅限于至多 16 个多核处理器。PGI 服务器生成的可执行程序限制 OpenMP 或自动并行程序使用的线程数。该数字最大值等于发起执行的处理器内核数的 16 倍。可执行程序能在任何兼容的系统上执行，无论是否安装了 PGI 编译器。
