GPU to 72 status...

[flashjh]

Thanks all. I'll still be able to compile.

So that's the top3 TF'ers left the project. (Well three of current top4)

Sorry to hear about everyone's loss. I lost my last grandparent (grandmother) early 2011.

Yes I'm definitely keen for this. And have been for sometime.

Some not so good news is that my father-in-law is not doing well, but we knew this was coming for some time......
If anyone is interested in some great TF GTX 580s or a whole i7 system, PM me.

Jerry, I'm sorry to hear this. Your participation with the MISFIT project was fantastic. I hope this is not the last we see of FLASHJH.


thx

@flashjh: Sorry to hear that... best of wishes to you and your father-in-law.

However, it raises the question: for those who are doing DCTF work (where we're currently over 500 days ahead of the wave), should we bump the release level to 71, and perhaps bring back in some candidates in the 30M, 31M and 32M regions to go from 70 to 71?
If so, I'd suggest we simply increase the current release level for DCTF, and bring in a few candidates at a time at the top of 30M for processing, and work down until we meet the wavefront, Then start working upwards from 31M.

Thoughts?

Unless my eyes are deceiving me, isn't most of 31M still stuck at 69? Shouldn't we be taking that up to 70 before thinking of taking other stuff up to 71?

Yes, it is most at 2⁶⁹. Perhaps a picture shows that most clearly (each pixel column is 0.1M):

Language can be so important...

The DC candidates at 31M are not "stuck" at 69. That's where we took them before moving on. And before we found ourselves with new tech....

Are you volunteering? Knowing there's more important work (LLTFing) to do?

Or, complementary, 30-40M TF level.

Speaking of LL-TFing, how many exponents/days is GPU72 ahead or behind the LL frontline? I'm thinking about doing some LL-TFing once I complete the 131-132M range to 2^70 (probably in ~2 weeks) .

Very sophisticated....
