I was happy to see the 'Speeding up Parallel GROMACS' paper.  I'd like to
the GROMACS patch for better all-to-all, as well as the all-to-all test
program referred
to on the paper.  I can't find it on the GROMACS site.

We've got a Cisco 6500 and when I run tcpdump during MPI runs I see a huge
of TCP lost packets with retransmits, and tcptrace confirms there are a
large number of restransmits.
I am trying to get our network admins to test the flow control setting
option on our 16-processor cluster.
