  • mpixlc, C compiler based on the IBM xlc compiler.

  • mpiCC, C++ compiler based on the Gnu g++ compiler.

  • mpicxx, same as mpiCC.

  • mpif77, FORTRAN77 compiler based on the IBM xlf compiler.
                xlf -qextname -L/usr/mellanox/lib

  • mpif90, FORTRAN90 compiler based on the IBM xlf90 compiler.
                f90 -qextname -L/usr/mellanox/lib
