AFAIK there is no freely available Blast for Beowulf, neither WU or NCBI.
I think SGI rewrote it to run on a beowulf - cluster. But they want to sell
it together with their hardware ... .
A single Blast job normally runs fast enough - so a very easy thing to do is
to write a script that splits up a multiple sequence query and distributes
it to the nodes. Another way to do it would be to add some pvm/mpi code to
the NCBI source code, that does the same thing as the script. Advantage
would be that the database is not reloaded for every query.
