Subject: [OMPI users] ompi-checkpoint fails sometimes
From: ananda.mudar_at_[hidden]
Date: 2010-05-11 17:35:53



I am using open-mpi 1.3.4 with BLCR. Sometimes I am running into a
strange problem with ompi-checkpoint command. Even though I see that all
MPI processes (equal to np argument) are running, ompi-checkpoint
command fails at times. I have seen this failure always when the MPI
processes spawned are not fully running ie; these processes are not
running above 90% CPU utilization. How do I ensure that the MPI
processes are fully up and running before I issue ompi-checkpoint
because dynamically detecting if the processes are utilizing above 90%
CPU resources is not easy.


Are there any MCA parameters I can use to overcome this issue?
