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!
