Actually, other's dumps... In graphic detail....

I had to hover over that link and see where it went. For a moment I thought you might have linked to some German website that specializes in a certain form of ... umm... whatever.

Just because German people are known for optimization doesn't mean necessarily they are bad.

Niccolò Machiavelli was Italian.

George W. Bush was American....

Last I heard, W still is American, worse luck, as is Darth Cheney, and a host of other evil ones.

Touché.

Finally had a factor in my TF. (and credited as such, so it wasn't an exponent that I added manually just to check the graphics card)
Happy that my card is still functional.
Back to crunching then.

Just a quick update...

Based on the /possibility/ that a new Mersenne Prime has been found (and, to be clear, I have no "insider" knowledge of this) GPU72 is currently directing some of its workers' firepower to the LL Category 4 which has already had a P-1 run done.

My thinking is that while new LL'ing workers will generally initially be assigned DC'ing work in the DC Cat 4 range until they've demonstrated they're serious and stable (where we're _years_ ahead), new workers who explicitly ask for them will get LL Cat 4.

We do currently have a reasonable buffer in all the LL categories, but I just wanted to ensure we can handle large amounts of assignment requests from new workers which are appropriately TF'ed and P-1'ed.

Iff (if and only if) this does turn out to be a real new Mersenne Prime we can adjust our targeting as needed and appropriate. If this doesn't turn out to be a new Mersenne Prime then we'll go back to "just in time" for Cat 1, 2 and 3.

Fine with me, you can feed all my workers with LLTF to 74, until I will have time/access to change the preferences in Misift. The DCTF is dying anyhow.

Now I hate you guys, if you kill all the blue, how can I make my cityscape any longer? It will all be green and ugly...

Most of my effort is now on What Makes Sense LL. DCTF has been granted a (brief) reprieve. I suspect Anonymous will keep running us towards the finish line though.

Laurv, don't worry after this we will tune and optimize the GPU TF programs until it is worth taking everything up one more bit level and the cycle will repeat!

Thanks in a big part to GPU72 all 3 of these range now have less than 200,000 Exponents unfactored (i.e. requiring LL/DC).

This is very roughly about 10% better than the number of exponents factored via the standard PrimeNet factoring limits.

GPU72 is just a very small part of this.

The true credit needs to go to Oliver ("TheJudger") and Bertram ("Bdot") for writing the GPGPU code which completely changed the Trial Factoring landscape, and "Mr. P-1" who used to coordinate this effort via e-mails and PMs which inspired the whole idea of GPU72.

Also, Mike ("XYZZY") for creating, hosting and managing this forum, and of course, George ("Prime95") for creating the GIMPS project in the first place.

And that is just a small list of those involved. It's nice being associated with a group of really smart people with different talent sets!
