GNU Compilers on Polaris

The GNU compilers are available on Polaris via the PrgEnv-gnu and gcc-mixed modules. The gcc-mixed module can be useful when, for example, the PrgEnv-nvhpc compilers are used to compile C/C++ MPI-enabled code and gfortran is needed.

The GNU compilers currently on Polaris do not support GPU code generation and thus can only be used for compiling CPU codes.

The nvhpc and llvm compilers can be used for compiling GPU-enabled applications.
