    While that would be nice, I need x86.

    It's been pruned now. :hs:

    Anyway he set up some dualie AMDs and he said it was great. Super expensive ... but great.

    Opteron 4-way or Xeon 4-8-way...

    Why? If you just number-crunching then processor archatecture doesn't matter at all.

    most cost effective would be a beowulf cluster of athlon xp's

    The software is Windows only.

    That's what I was thinking. Put it in some cheap rackmounts from Wal-Mart.

    No ECC RAM, no 64 bit, slow processors.... yeah you'll go far with that kind of setup :ugh2:

    You're telling me that one dual opteron system is going to crunch faster than 10 athlon XP systems? or maybe even 20 depending on the cost.

    Ah, and I didn't know that walmart had rackmount systems :rofl: if true...

    Where are you getting these exaggerated 10x or 20x figures? Whoever you're buying CPU parts from is raping you on prices. :rolleyes: And yes, I would bet that a dual opteron system would crunch faster than the equivalent priced number of Athlon XP systems. There is a huge amount of performance overhead on distributed computing setups, especially if you're not using a fast interconnect system which I'm guessing you wouldn't if you're looking at Athlon XP systems.

    Also, there is a reason why servers and supercomputers use ECC RAM. What happens if you're getting errors in your computations due to memory problems (very common problem)? Are you going to pull out 40 sticks of memory and run Memtest on each one (you need to run the full pattern which can take hours) just to isolate a memory problem? You wouldn't have that problem if the chipsets for that CPU supported ECC RAM.

    And finally you're ignoring operating costs. Leaving a computer running 24/7 can take up to $50/month in electricity. Not to mention extraneous costs and impacts on reliability if you don't have the HVAC to deal with all the machines (10-20 computers produce a lot of heat).

    this guy knows what he's talking about

    for number crunching, 64-bit and ECC, so that pretty much puts you in opteron territory

    I doubt the app I am using will benefit from a 64bit processor, but i'll keep the ECC in mind. That was a very informative post, Toaster Oven.

    Earth Simulator if you can afford it...

    Oh... Oops... sorry no windows...

    I had say the Opteron for number crunching when running it on Linux platform.

    If it's for windows... then I guess Opteron still... But that's because the latest P4 kinda suck ass...

    Well... this was old school, but my buddy built a 'hive' of like 60 386's. He shut it down after a month, but it didnt cost him anything. Except for when he got his utilities bill.... :owned:
