uh.. just a quick comment on bioinformatics and parallelizing things...

please note, that most of the bioinformatic problems are already
embarrassingly parallel and, with the new genomes showing up at an 
amazing rate, getting more and more so. Thus, in most cases, it just
doesn't make much sense to parallelize anything - if one's got to
run 300x4000 blasts against a library of 300x4000 sequences (ie 300
genomes, 4000 genes/proteins, all vs all) the simplest solution -
a lot of nodes, blast optimized for a single cpu and a decent queing
system will ultimately win (as long as one stays within the same
architecture; FPGAs are a diferent story ;o)
