In an earlier thread I mentioned getting the following error when trying --bind-to core option with mpirun. I was told that numactl and numactl-devel need to be installed. The sys admins have installed these in our cluster and I've rebuilt OpenMPI, but I still get the same warning. I wonder if there's anything more I need to do.
WARNING: a request was made to bind a process. While the system
supports binding the process itself, at least one node does NOT
support binding memory to the process location.
This is a warning only; your job will continue, though performance may
