Oh, btw, is the last version of mfakto (the one which speeds up the 74th bit, see mfacto thread) available for windows? Exe, and production ready? In the light of the last discussions in this topic, about Cat4, I could switch a 7970 from "max 73" to "let gpu decide", but the version of mfakto which I use is too slow for this card for bit 74.

The latest code passed all tests except for the general performance comparison. For an unknown reason, some kernels are still slower than before. This makes me hesitate to release it ...

GIMPS is starting to release exponents in the 80-81M range TF'd to 2^71-72. For Research is grabbing the loin's share of those assignments the rest seem to be for P-1 testing.

Was just surprised that that range is starting to be operated on.

Was it completely random that ~2000 assignments were taken up and dropped over the course of four hours in the 80-81M range?

Not quite sure if it was completely random or not.

According to my logs, Primenet was having some serious issues in communcations today. Probably at least correlative, if not causal.

Definitely not intentional on my part, but "when the cat's away, the spiders may play....

This coming weekend the company is moving offices. I may no longer be able to use two of the borged machines for TF. On the weekend my progress will be basically stopped (down to a single GT 430; my GTX 760 is out of commission at the moment). So that means about 70 fewer exponents TF 73->74 over those two days. More released at 73 bits I guess.

chris,
can you enable 38M and 39M range for DCTF
or will misfit start fetching there automatically
thanks

But that would sabotage my nefarious plan to finish all the DCTF at GPU72! ;)

Have you considered the following....
[QUOTE=chalsall;387624]So everyone knows, there is just short of a year's worth of DC Cat 4 candidates already appropriately TF'ed, while we're still releasing some LL Cat 4 at only 73 bits.

Or, in other words, for those doing TF'ing, please don't feel the need to do any additional DC TF'ing. If anything, anyone doing DC TF'ing should move back to LL TF'ing (if so inclined).[/QUOTE]

As Uncwilly pointed out, I mentioned on another thread that we currently have quite a bit of DC candidates appropriately TF'ed. And, also, HBendtz is independently taking the 38M range from 69 to 70.

But, since I want to facilitate and cooridinate the work that people want to do, I'll bring in a few thousand candidates in the 39M range only at 69 for processing.

[QUOTE=Prime95;387732]This wasn't as minor as I thought! Nearly 1000 cat4 DCs have been assigned in the last day. At that rate, we'll chew through 60000 cat4 DC assignments in the next 60 days! I don't see that as much of a problem.

I wonder why our retention rate is so low or why so many stress testers can't read the initial startup screen and not get Primenet assignments.[/QUOTE]


looks like we will be releasing no more Cat4 LLs below 74 anymore for quite some time, but the buffer for the Cat4DC (which seems to be about 7000 assignments) will run out not in close to a year, but rather in ... a week?
