Ok, I a am newbie supporting the a HPC project and learning about MPI. I have the following portion of a shells script:
export OMPI_MCA_btl_openib_allow_ib=1 export OMPI_MCA_btl_openib_if_include="mlx5_0:1" mpirun -machinefile ${hostlist} \ --mca opal_common_ucx_opal_mem_hooks 1 \ -np $NP \ -N $rpn \ -vv \ My question is there a way to take the '-mca opal_common_ucx_opal_mem_hooks 1 ' and make it into a environment variable like the others ?
