Also, it's 14336 (14<<10) sixcore CPUs (multiplying up to a peak 2.93GHz * 4 FLOP/cycle * 12 cores/box * 7168 boxes of just over one petaflop) and 7168 Fermis  so 7168 boxes each with dual hexcores and a Fermi. Not a cheap machine: maybe 400 million yuan.

Thanks for the windows executable.
I've been running it. I have a nvidia 460GTX running on Win7. I've been grabbing TF work manually. On my machine it seems to average about 2GHzdays work per hour. Is that what I should expect? (I think that figure is awesome btw)  Craig

Hi Craig,
Quote:
 exponent size  bit level(s)  CPU type/clock  settings in mfaktc.ini (if changed from default) When providing performance numbers please copy&paste one or two lines of the mfaktc output starting with "class xxxx:". I'm not thinking in GHzdays. A GTX 460 should provide similar speed to a GTX 465, perhaps a little bit slower. If the CPU ist fast enough you should see something like 150M/sec for a exponent around 100.000.000 at bitlevels about 64. Oliver
