Hi Bob

Is this the same mpiBLAST as mpiblast.lanl.gov ?  if so you may be
interested in a patch to "allow mpiBLAST to run on IBM BlueGene"
(http://mpiblast.lanl.gov/Downloads.Patches.html) 

More promising is mpiBLAST-pio, which at a quick glance, looks like a
mpiBLAST that makes use of mpi-io to coordinate client writes.  I've
never played with it, but that sounds like a more correct solution to
your problem.
