In making the leap from 1.6 to 1.8, how can I check whether or not process/memory affinity is supported?
I've built OpenMPI on a system where the numactl-devel package was not installed, and another where it was, but I can't see anything in the output of ompi_info that suggests any difference between the two builds. Both builds on Linux RHEL6 systems, just different hosts. both Sandy Bridge. I guess I can try -bind-to-core on both systems and -report-bindings, then see what output I get. I was just wondering if there's a quick way to tell by using ompi_info. Thanks Ed
