[mvapich-discuss] Setting default mpicc/mpif77 CFLAGS, FCFLAGS

[Novosielski, Ryan]

Hi there,

Is there a way to configure the mpicc/mpif77/etc. commands to use a specific set of CLFAGS and FCFLAGS when building software? I have read in the Slurm docs that what you want to do is build MPI-aware software with Slurm’s PMI linked in, and that the easiest way to do that is set the default for the mpi compiler wrappers to do that. I know how to do this with OpenMPI and I’m assuming MVAPICH2 has a way also (with MPICH2, you appear to use a set of environment variables like MPICH2_MPICC_FLAGS, etc.). I am not finding this anywhere in the documentation, however — in fact, the build section is very sparse in general.
