Hi I want to perform a MPI program across the instances. I've already done it on a traditional and virtual cluster, so I'm pretty sure about the healthiness of my installation. Unfortunately I can't perform it on a cluster of OpenStack instances. My MPI program is HPCC, it stops at the begging of MPIRandomAccess. I would be so grateful if anyone had a similar experience or can guess some possibilities and solutions. Regards, Reza -------------- next part -------------- An HTML attachment was scrubbed...
