Long ago, and there is the only one working well for drv 4.x with cc 2.0. If you have anew card (580, 590, Tesla) then I highly recommend it to you.

Now THAT's not fair! Unless your ETA is longer then 16 hours, which would be ok for me :P:P (ETA 15:53)

A faster CPU may be unfair, but a GPU is just cheating!
Actually, it will be fairly close, we'll see who gets there first...

What kind of CPU goes that fast if I may inquire? I thought from looking at the CPU benchmarks that the 2400 would be close to the top but you've doubled it's speed. Or did you just stop all the other workers and use all the cores?

i7-920 @ 3.2GHz. On 3 cores I get 0.007s iterations. On 4 cores I get 0.006

And a faster GPU would be cheating cheating. But in math, minus and minus makes plus, so I am not cheating at all

But anyhow, ET is at almost the end, and I just started, so he will beat us even with the hands of his CPU tied on its back...
edit: and he is on GPU too!

Well, I'm not sure about that...
I asked for the exponent 25977901 BEFORE the official opening of the low LL-D system.
Since I was warned that the feature was still not running, I decided to TF the exponent from 67 bits to 69 bits and then do a LL-D with CUDA by myself.

The net result is that I can't see neither credit for the TF done nor the assignment on the Low LL-D on GPU to 72.

Hope Chalsall will help out, or you will be the first one to officially enter the stats...

You do see the credit for the TF work you did.

And today I will create the "Assigned" records for your "tricked" assignment, davieddy's test assignment (both of which are special cases because GPUFactor still owns them) as well as the half dozen handed out by hand to requesters before the web interface came online.

So, short answer, whoever finishes first should be determinable....

Yes, I do
For strange reasons I thought the wxponents were sorted.

This afternoon I finally finished up a big bunch of TF exponents in the 28M range that ckdo sent me a month or so ago — this was just before the GPU to 72 project got up and running.

Now at last I'll be able to turn both instances of mfaktc to work on this project.

With regards to who will complete the first "GPU to 72" assigned DC, please see:

http://www.mersenne.org/report_expon...xp_lo=25094677

Or, at least, this is the first I have noticed manually, as I update the database with the appropriate "Assigned" records for those few assignments I provided via PMs.

Congratulations delta_t. And thanks for playing!!!
