Not particularly - I've never been involved in optimizing apps on large NUMA systems. Our uses of NUMA at Google have all involved faked-NUMA nodes, assigning nodes to jobs to provide crude memory limits. I suspect that there aren't very many "simple" tests out there. Google search for [hpc numa tuning] turns up a few likely pages that might have pointers to suitable applications.
