The numbers are reversed but who's really counting. :-)

Also, it's 14336 (14<<10) six-core 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 hex-cores 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 2GHz-days work per hour.

Is that what I should expect?
(I think that figure is awesome btw)

On a GTX465 (the nearest equivalent I have) I am getting the equivalent of 4.6 GHz days per hour on 100M digit exponent. This is on 64-bit Linux but the difference between Linux and Windows is negligible on v0.13. However, the size of the exponent does matter. If you are testing a smaller exponent then it will run slower.

please provide some more information:
- 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 GHz-days. 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.
