ROFL!!! Thanks mate!

It's really sad that we're not going to be able to continue following the green line. Oh, well... Looking forward to the next MP in the next year or so!

OK, just so everyone knows, I've brought in a couple of thousand candidates in 100M to take up to 74 bits. These are in 100.[89]M -- the high end of the range to take advantage of George's new sort TF desc assignment clause.

This is in preparation for Cat 2 entering 100M. I'm still wrapping my head around how to deal with Cat 3 and 4 -- they are climbing so fast that it's going to be a bit tricky figuring out how best to "feed" them 74-bit candidates. Probably best to just do a few hundred at the top of each range, and wait for the wavefronts to scream through.

The good news is there isn't actually a whole lot of Cat 3 and 4 being assigned, and many of them will expire. They are climbing so fast simply because of the speed Cat 0, 1 and 2 are being done.

Truly, WOW!!!

As always, feedback welcome. As Red Green says, "We're all in this together.

Well, 32 mod 24 is 7 which is close to 5. Very close for an IT estimate.

Those of us who dare to try to program can relate. Thanks for the laugh.

I read that as f(x) = 2^x.

Yes, thanks for sharing. So few understand the kind of work we do...

IMHO ...as summarized above... most expire anyway so focus on Cat 0,1...maybe 2..

I don't know if "GPU Factoring" is participating in GPU to 72 or not, but considering the desire to try to stay ahead of the wave front why would someone want to trial factor an exponent that has had P-1 done, and on top of that has a PRP test completed?

As I recall, "GPU Factoring" is the PrimeNet username of the GPU72 spider that grabs work. It's always reserved as Trial Factoring on PrimeNet, the actual work performed by the GPU72 user it's assigned to may or may not be TF.

In the case of 100832383, I'm not sure if the GPU72 spider pays attention to the fact that a PRP has already been done, even though the 100M exponent has only been TF'd to abnormally-low 272 (an illustration of the TF shortfall we're experiencing).

Maybe it should pay attention to that, because in my view any work other than a PRP double-check would be a waste of resources at this point in time.

Guys, please forgive me for this, but fuck me!

This situation has been unexpected, and I'm doing the best I can. Mistakes might happen. Sorry about that.

It takes more than a little bit of my time to manage this. All unpaid.

My deepest appoliges for any mistakes I make.

Oh I hope you didn't take me wrong. I was just pointing out that if someone was reserving exponents via an errant script (I didn't know who GPU Factoring was) that they would want to know.

We've all been there, done that, and got the tee shirt.
