    for what its worth, we use Paracel BLAST and are also considering
    mpiBLAST-pio to take advantage of a parallel file system

Cool. mpiBLAST also uses mmap'ed IO though. That hasn't changed. They just spread the IO to each process to take advantage of the parallel file systems.

We have a nice RPM build for mpi-BLAST-pio that a number of folks are using. You can grab it from http://downloads.scalableinformatics.com/downloads/mpiblast/ . And a shameless plug for mpiHMMer: http://www.mpihmmer.org/ while we are at it :)
