We certainly don't use any low latency interconnects here at the Sanger.  We 
always considered it more cost effective just to use the money to buy more 
nodes.  As you say, there's relatively little current bioinformatics software 
that requires MPI; many of our problems are embarrassingly parallel and can be 
broken into small enough independent subproblems that they can be run on poorly 
interconnected small machines.

The only thing a decent interconnect would gain us is a better position on the 
Top 500 list.  :-)
