Question about this: do the CPUs in the list correspond to the Linux virtual processor IDs? E.g., do they correspond to what one would pass to numactl(1)? Also, a minor quibble: it might be a little confusing to have --bind-to cpuset, and then have to specify a CPU list (not a CPU set). Should it be --cpuset-list or --cpuset? -- Jeff Squyres jsquy...@cisco.com _______________________________________________ devel mailing list firstname.lastname@example.org https://lists.open-mpi.org/mailman/listinfo/devel
