I don't know remember Torque does, but core binding and (Linux) cpusets
are somewhat orthogonal. While a cpuset will obviously restrict the
processes somewhat, it won't provide the necessary binding (at least
unless the resource manager launches the processes and uses a cpuset for

I assume you can determine whether or not it's the kernel rather than
ompi/ofed by booting into the old one.
