I wanted to write Myrinet, not Numa. I haven't seen any numa
(non-uniform memory access) benchmarks.

Just for record:

  With MPI on Myrinet, the latencies are about 11 microseconds,
  corba/myrinet 20, corba/100Eth 150microsec, gigabit
  ethernet(VMI/TCP) about 70microsecs.  Infiniband is probably best,
  about 5microsecs.
