I have always thought of MP systems as something that didn't run anything faster but what they would do is run additional applications equally slowly. The compiler's on Cray's were the best the world had to offer in 1990. However, when you turned on full MP and vector support, a 486-PC would out compile it on a line for line basis. The PC was fast because it didn't have to worry about pipelines and producing do-loops that could be run on more than one processor. > > My next system will be a new workstation.

What is interesting (frustrating is the word) is that seti@home runs 25% faster on the T-bird on Windows 2000 than it does on FreeBSD 4.3.
