Anyone familiar with cluster computing or slave/master computing? I have a few old computers lying around (they aren't too terribly powerful) and I wanted to get some use out of them. I've been looking around and the best solution I've come up with so far is Synergy, but that's just a KM switch, so they're still 3 separate computers working independently.
I don't necessarily need to do heaving computations on it, but I would like to combine their efforts to turn 3 crappy computers into 1 decent 3-core computer. I know from research that this is quite difficult with such a small scale and not really worth it unless I want to render video or figure out genetic folding.
