Subject: Re: [OMPI users] Binding to Core Warning
From: Ralph Castain (rhc_at_[hidden])

It means that OMPI didn't get built against libnuma, and so we can't ensure that memory is being bound local to the proc binding. Check to see if numactl and numactl-devel are installed, or you can turn off the warning using "-mca hwloc_base_mem_bind_failure_action silent"
