[QUOTE=chalsall;324811]Excellent!!! :smile:

It can be argued that LL P-1'ing is currently more important than LLing (as long as enough memory is available and S2 is done).

If only we had a GPU P-1 program.... :wink:[/QUOTE]

+1! However, with 2 GPUs running mfaktc 2.0, I still need to do something with the CPU. Hence, I'm now running all six cores on P-1. With 4 HighMem workers I've seen Relative Primes drop to 432 at times, instead of 480. I still get B-S kicking in at the E=6 level.

This will all come to a screeching halt for ten days, starting in a day and a half. Thanks to the generosity of friends we are going to the Philippines. I have never been outside of North America before. (That includes pretty far down in Mexico, but Mexico is still North America, geologically.)

Don't believe.

Know.

Damn lucky you...

Hmmm... does Canada count when you're in the US? :missingteeth:

What? You mean the 51st state? :sirrobin:

Crap.

[QUOTE=kracker;324849]Crap.[/QUOTE]

Indeed....

Must be nice, living in Barbados... Hmm...

Not so very much.

We've been asking for a Freedom of Information Act for years.

It's always promised, but somehow never delivered...

Since 1966....

Damn, that's a lot of RAM. I only have 1 core doing P-1, but that 1 core uses up all of my memory. All the other cores do LL work, and the GPU does TF.

So if you have a 6-core, 64GB system, 4x high-mem workers is a very reasonable setting.
