Hi

 

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?

 

Thanks

Ananda
