this idea has been rattling around in my head for a while and this seems to be the place to ask. how do i go about building a computer cluster, also is it possible to do it under win xp? what is needed, as far as hardware? I dont have the money to go out and get a brand new computer but have access to a few older computers, about a year and a half old, and would like to hook them all up toegether. I would appreciate and help in getting my project started.
