Hi, Thanks to Jon Saenz and Chris Baker for helping out with fast linear algebra and statistical distribution routines. Again, I have a tangential question. I am hitting the physical limit of the CPU (meaning things have been optimized down to assembly level), in order to achieve even higher performance, the only way to go is hardware. Is there any recommendation for fast machines at the price range of a few thousand dollars? (I cannot afford supercomputers or connection machines.) My purpose is to run Monte Carlo simulation. This means that a lot of scenarios can be run in parallel fashion. Of course I can just use regular cheap Pentium boxes... but they are kind of bulky, and I don't need any of the video, audio, USB features (I think 10 machines at 1GHz each would be the size of calculation power I need, or equivalently, a single machine at an equivalent 10GHz. Heck, if there are some specialized racks/boxes, I can wire the motherboards myself.) I am wondering what you people do for heavy number crunching? Are there any cheap yet specialized machines? What about machines with dual processor? I would imagine a lot of people in the number crunching world run into my situation, and since the number crunching machines don't require much beyond a motherboard and a small hard-drive, maybe there are already some cheap solutions out there. thanks!
