Have you tried testing without using the NFS? So setting the mca-params.conf to
something like:
crs_base_snapshot_dir=/tmp/
snapc_base_global_snapshot_dir=/tmp/global
snapc_basee_store_in_place=0
This would remove the NFS time from the checkpoint time. However if you are
using staging this may
Dear OMPI Users,
I’m now using BLCR-0.8.2 and OpenMPI-1.5rc5. The problem is that it takes a
