[mvapich-discuss] MVAPICH2 2.1a, PMI2 interface, SLURM srun parallel luncher

[Jonathan Perkins]

Can you try just using --with-pm=hydra (still keep using
--with-pmi=pmi2)?  I haven't tried this in a while but I know that early
in the process I experimented with this and we where in fact able to
still run slurm jobs since both slurm and hydra support pmi2.

But I would love to have them as well. Is there any change to do so or I need to have two different MVAPICH2 installations?

But when srun is used, I can manipulate it with --cpu_bind correctly. So I assume that Open MPI default is disabled when srun is used. It will be nice if MVAPICH2 adops the same strategy.
