    I was looking at new computers today and was surprised at the number of new models with dual processors like the AMD 64*2. My question is do DC programs like Seti and Einstein take full advantage of a computer having two processors? In other words, would I get more WUs done in a year with a computer that has one 3.2Ghz processor or one that has two 2.5 Ghz processors?

    I've just placed a purchase order for a new LIGO data analysis cluster at UWM. It will be quantity 640 AMD Opteron 175 systems: a total of 1280 CPU cores. The systems are based on Supermicro H8SSL-i motherboards with 2 x 1GB of DDR/400 unregistered ECC memory and a single 80GB SATA drive.

    (By the way, the Opteron 175 is identical silicon to the AMD64 X2 4400+.)
