Perhaps 2 is reasonable if a person requests a standalone P-1 assignment.


It seems less reasonable when one receives a PRP assignment for a number that has not yet had P-1 done on it. (I have...

I appreciate the news from you both, and am sure that eventually all the dust will settle.

I just wanted to make sure that someone was aware there was some oddness going on.

Unexpected exponent expiration

My first XXX-rated thread!

I observed this morning that one of my assignments had been expired. It was M75642647, cat 1 when I started it and cat 0 now.
But it was started promptly, reported on...

RAM is 16GB of DDR4 at 2400MHz.

CPUs are reporting 70°C.
The CPU status report in CAM is reporting "core clock: 3990 MHz". Does this mean it is self-throttling rather than maintaining 4.2GHz?...

Unexplained slowdown (affinity problem?)

The 2nd exponent on this machine came back as a match. That plus no loud alarm bells going off is encouraging that I may not have bad hardware.

New computer - first exponent is a mismatch

Always a bit frustrating, but especially so when it's a new machine and you don't know if the machine can be trusted or not.

This would be an interesting list to see.

I suspect there are very few large exponents on the list -- finding one 60- or 70-bit factor of a million-digit number leaves a very large nut to crack.

P-1 stage 1 only
