Is there a way to have MPICH2 select which ethernet interface to use
if you are using SLURM to launch jobs?
I.e., I'm compiling and running my MPI application with:
mpicc foo.c -L/path/to/slurm -lpmi -o foo
srun -N num_nodes foo
This seems to always choose eth0, but I'd much rather have it use ib0
(IP over InfiniBand). Is there a way to make it use ib0? I didn't
see anything about this in the user guide.
Any insight would be appreciated; thanks.
