GPU to 72 status...

chalsall · 2011-11-28, 01:50

Just for your information.

As of midnight tonight (2011.11.27), the GPU to 72 project has found 129 factors for LL candidates by way of GPU factoring which would not have otherwise been found, saving more than 258 needed LL/DC tests.

It has also found 40 factors for DC candidates which would not have otherwise been found, saving approximately 40 DC tests.

It has also found 31 factors for LL candidates by way of P-1 testing which might, or might not, have been found based on the amount of memory available to the LL testers which are supposed to do the P-1 work before the LL work. Saving approximately 62 LL/DC tests.

200 factors found in total.

I found another P-1 factor yesterday morning, but only reported it 20 mins ago...

*2 factors that were discovered earlier this week. Just figured out the other factor was in fact from GPU272...

Chalsall, moderators, this deserves a sticky.....in a very good way.

Might want to handle this like the severe problems thread, and just keep the handful of posts that remain relevant.

Now, as for what GPU 2 72 offers the GPU owner...the *BEST* exponents with the easiest control to TF, P-1, or LL, as you may desire. Unless you are quite diligent, you will find more factors with GPU to 72, and help more with LL milestones, than with any other method of getting assignments.

OK, it's been almost exactly a month since development started on the system, and approximately three weeks since Workers started using it.

I think we all believed were having a positive effect on the overall GIMPS effort, but this belief was based on subjective opinion rather than hard data. This has now changed.

I have updated the Overall System Status report to include the amount of LL/DC and P-1 work being saved. And I have to say, even I'm surprised...

Code:

Those GPUs are just amazing! Thanks for all the work everyone!!!

Thank you for the very kind words kladner. You are most welcome -- it's nice being able to give back to the community.

But, could I ask you (and others) to please stop with all the bowing? I know it's just a way of communicating respect through an emotionless channel, but it actually makes me a little uncomfortable...

I am simply standing on the shoulders of giants (George, Scott, Oliver, James, Linus, Monty, all the GPU and P-1 workers, et al...).

The feeling is understood. Won't do it again. But the thanks remain.

Thanks. And the "you're welcome" remains as well...

BTW, Dubslow and I started a discussion here which I felt would be better under it's own thread. Please have a look at the How should we compare GPUs to CPUs? thread.

Feedback, thoughts, etc very much appreciated.

Welcome to the 100 P-1 club delta_t.

See you at 500???

At first I had no idea what you were talking about, my first reaction was that I've done thousands of P-1 over the years, but then I realized I hit 100 P-1 turn-ins on the GPU-to-72 site.

So yes, I'll see you there at 500.

Is possible to run both the GPU and my Quad at the same time? Will this overheat or shorten the life of my computer in any way?
