Default P-1 laggards again

34 to go now to 108M first test, 10 of which are P-1 assignments, 9 of which have shown no update in the past 4 weeks. Deja vu all over again. https://www.mersenne.org/assignments...xtf=1&excert=1

Maybe some of them are actually PRP but reserved as P-1? Getting P-1 assignments is much easier because there's no assignment rules.

No, these are P-1, but are stalling out and not reporting in.

Most have reported at some point where they were on Stage 1 or Stage 2.

These were not in the Cat 0 range when they were assigned. And there are well known ways to grab an assignment if you want even if you aren't "eligible" for it.

Even a lowly 2GiB ram Pentium M 750 can run a 108M P-1 in an estimated 2 weeks.
Gpuowl on a Radeon VII can knock one out in under an hour.

If you see me in danger of being the last to finish a range in the future, let me know ahead of time and I'll adjust the workers to make the results appear on time.
M107148487 appears to be the smallest untested exponent, which was assigned to George Woltman.
It showed no progress in the last 3 days.

He is using AMD GPUs, so there will be no progress updates until the result is turned in.

Thanks for the heads up. I moved it to the head of the queue. Result in 2 days.

In the future it is best to PM me, as I do not always read this thread. If I don't move an exponent, it will take about 20 days.

He's using Radeon VIIs with rocm driver on linux, and memory upclock to ~1200MHz, so gpuowl should complete a 107M PRP in ~1 day. Python is standard in Linux IIRC so it can easily be automatically submitted and more work obtained using gpuowl's primenet.py script.


edit: I see now he has responded, and sorted the work queue involved. I wonder how deep a queue is common for wavefront PRP.

On vacation, will return on the 26th. Worse yet, all but one machine seems to have lost internet connection. Hopefully, they are still crunching and I'll upload a bunch of results and proofs on my return.
