I brew a new Debian package for Torque4 and was testing the
installation. I figured I could configure it and see if everything
connects, etc. No performance test were done on this virtual machine ;-)

I figured out that the num_numa_nodes parameter was also renamed.
Is there a way to have non-NUMA nodes in the same cluster?

I removed --enable-cpuset and --enable-libcpuset from the configure
call. Do I still get process binding?
