GPU to 72 status...

[Chuck]

Yikes — I see there are now 18,000+ DCTF available in the 31M range. Perhaps I should devote one day per week to working on these.

OR, Chris could get really clever and create a "blended" option for getting TF work which would include the appropriate mix of LLTF and DCTF.

No. I'm not that clever...

LLTF is the most important work right now.

Only by explicit request will DCTF be made available....

Put a few 31M expos onto my spare GPU (GT640, 73GHzD/D).
30 expos (1.5 days ) and found 2 factors.

Thanks.

We're interested in the empirical and theoretical value of factors found / factoring attempts across a large sample set.

Unfortunately we don't have infinite time, nor infinite candidates. We work with what we have.

I would have already cleaned 4 expos (two rounds DC in two cards), and being well into the half of the fifth/sixth clearance if I would do DC all this time.

When operating near the crossover point, some will be "jinxed" and someone will be "blessed".

I am trying to prevent those that decide to do 100M digit LL's without doing the TF from throwing away cycles. There are ~1500 LL's assigned in the range and there is not nearly that many that have taken the expos to 77 or higher.

BTW, I prefer to TF there than LMH TF generically. The borged boxes are not doing any LL's, because they are borged.

I found 1 factor out of 100 tasks in the 31M range on a GTX480/GTX470 rig, which is somewhat average I believe.
Even if CUDALucas would clear more exponents per day, I would still rather do TF (and clear a bit less exponents), since CUDALL gives ~25GHzdays/day and DCTF 300+GHzdays/day for each card.

Yes, I agree that what you're doing Makes Sense^(TM). Those who are attempting LLs up there, on the other hand....

That would be handy and appreciated. We only need about 120 a day to stay ahead of the wave, and we've got about a 10.4 day lead at the moment.

I have adjusted the DCTF assignment form to default to TFing to 70 again. For bcp19 et al who want to keep going to 71 in 33M, just changing the pledge level to 71 will default to candidates at 33M or above for "What Makes Sense".

If anyone wants to take 31M to 71 (not recommended), just change the Option to "Lowest Exponent" and it will assign candidates in the 31M range.

I'll just grab from the default then, it'll be a few days before I grab more though.

I realized I hadn't answered your question...

Taking into account the fact that all of 32M is already at 70, and the 652 in 33M which are at 71, we are currently about 191 days ahead of the DC wavefront.

As to the number of 31Ms to take to 70, that is currently reported on the Available Assignments page; 18,404. At George's suggestion, I've brought in everything available in 31M so if we fall behind in this new work, Primenet will assign candidates from 32M.

There are currently 713 candidates assigned for DCLLing in 31M which are only at 69. If and when they become available (read: expire on Primenet) Spidy will bring them in for processing.

So, if you're willing, moving back down into 31M to 70 would make sense... We definitely have the time....
