Hello, (for all who are interested) I finally obtained access to a linux platform running 2.2.17 on a 2x500 Mhz alpha machine (Compaq's testdrive program). Below are my results: Linux 2.2.17 on 2x500 Mhz Celerons: parallel app = 1.48 times faster than sequential one. Linux 2.4 on a 2x1 Ghz PIIIs: parallel ap = 1.57 times faster than the sequential one. Linux 2.2.17 on a 2 500 Mhz Alpha CPUs: parallel app = 1.76 times faster than the sequential one. Interesting how hardware changed the numbers. Another interesting thing is that the same application when run on a dual Alpha running Tru64 does not obtain the speedup Linux provided on the Alpha hardware. In my limited example application SGI IRIX 2 CPU platform provided 2.25 times the speed of the sequential application and Sun Solaris 1.99 times the sequential application (also on a 2 CPU machine). All these numbers above are when the same code utilizing pthreads was compiled and run on these various platforms. On all of the tests I have used a pool of three threads waiting to get work to do. The testing was done on a set of various sequence files that I believe represent most of the types of data / sequences that might be used on this program.
