Hi Pavan,
Can you try the following:
# Use the slurm launcher, and user-specified resources % mpiexec -f hostfile -launcher slurm -n 4 ./hello
Works.
# Use the ssh launcher, and user-specified resources % mpiexec -f hostfile -launcher ssh -n 4 ./hello
Works.
# Use the ssh launcher, and slurm-specified resources % mpiexec -rmk slurm -launcher ssh -n 4 ./hello
Fails.
# Use the slurm launcher, and slurm-specified resources % mpiexec -rmk slurm -launcher slurm -n 4 ./hello
Fails. So it seems as if the SLURM-provided host list is somehow causing trouble...
