I tried searching on this topic and couldn't find anything, so...
I just got my first P4 system with hyper threading. I've read that for whatever reason P4s with HT run two distributed computing type clients simultaneously with very minimal performance impact on each other.
Right now I?m running United Devices cancer research thing exclusively on all my systems, and I?m wondering how I could set it up to run two copies at once (if that?s possible). Can I do something as simple as install a second copy in a different directory, and then both will be grabbing different work units and not interfere with each other? (Even if that works, would it confuse the UD servers, when they're sending and recieving work units from "two" computers with the same name?)
Does anyone know if the performance really is close to double (or at least improved) when running two instances of UD? It's kind of counter intuitive, but I know I've read results people have posted (from Seti, I think) where (as an example) maybe running one instance a work unit takes 3 hours, and with two instances a work unit takes 3.5 hours.
As long as I'm asking on here, is there a command line version of UD that runs faster, or a way to queue work units so my 'puter always has something to do?
