Hi,
in February I ignored the announcement of an Apple-optimized version of
Blast that could run 5 times faster on a 1.0 GHz G4 than the standard
NCBI version of Blast runs on a 2.0 GHz P4, but now, after Apple
started building dual-G4 1U rackmountable servers, that announcement
becomes interesting.
Apple/Genentech BLAST provides improved
accuracy and
speed over the standard NCBI BLAST, depending
on search
parameters such as the nucleotide
match-length. For certain
common searches this version enables a dual
1-GHz Power
Mac[tm] G4 computer to deliver more than five
times the
performance of a comparable 2-GHz Pentium
4-based
system running the standard NCBI BLAST.
"Apple and Genentech have dramatically
increased the
performance of an important tool that
biomedical researchers
use every day," said David Botstein, Ph.D.,
professor and
chair of the Stanford University Genetics
Department. "I'm
impressed and delighted that a machine that a
regular
scientist can afford and run, such as the
Power Mac G4, is
as fast, or faster, than the industry standard
BLAST running
on more expensive machines."
I wonder if anyone could do the following benchmark (on a dual-G4) and
publish the results?
Blast human chromosomes 21 and 22 (query sequences) against the genome
of pufferfish (database). Use default parameters for blast (i.e., no
word length of 40, etc.) and an E-value of 10^{-4}. If possible,
submit both jobs independently and simultaneously, so that one CPU is
blasting chr 21, while the other CPU is blasting chr 22. Thanks!
Ivo
