Some run times here testing the new hosts. Ofcourse there is still contention inside the switches with swallowtail.

C-00 is on Infiniband, C-01 is on Gig Ethernet switch. Please note that if N⇐8 all MPI message passing remains local to the host and does not travel through the switches. So these are not benchmarks.
