At The University of Texas System Center for High Performance Computing,
we have developed a PVM based version of BLAST running as part of GenTools(TM).
GenTools is a distributed genomic tool suite designed to provide
the experimental molecular biologist and/or geneticist transparent
access to computational tools on high performance platforms. (To
obtain more information about GenTools, please send E-mail to
gentools at chpc.utexas.edu.)
For example, blastp, comparing a 799 residues query sequence
versus PIR, release 32 (40.298 sequences) ran on a net of up to
8 SPARC 2 workstations (times are elapsed times in seconds):
# processors time
--------------------------------
1 194.6
2 100.1
4 53.2
6 38.1
8 29.6
These timings were obtained with blastp, version 1.2.5 and PVM,
version 2.4.2. We are now using PVM, version 3.0, but I haven't redone
the timings yet.
