Generally, users ought run TF to GPU72 bounds, P1 to PrimeNet bounds the one and only time P1 is run, and PRP with proof, or move on to other exponents. And note there may be a downward adjustment in TF bit level and P1 bounds targets coming, thanks to the introduction of and transition to PRPproof & CERT, reducing verification effort from equal to a primality test, to ~1% of one.

Per mersenne.ca lookups, RTX2080 TF: 2623 GhzD/day LL: 65 ratio: 40.4:1 Excess TF at https://www.mersenne.ca/exponent/205132043, 37602. GhzD/day (14.3 days excess TF) P1 needed 61.87 GhzDays (0.95 days needed) LL estimate or PRPproof: 1750.4 GhzDays (26.9 days; recent Gpuowl takes about 0.6x as long, ~16.2 days), actually ~3% less if allowing for some probability of a P1 factor found. Dirk's kit, Dirk's call though. Last fiddled with by kriesel on 20200808 at 17:57

Predict M52 is equal opportunity debunking within limits.
Our collective record of predicting composites in Predict Mxx remains perfect so far. The computations, not so much. On the one you linked, I had a gpuowl crash during PRP proof generation, and got a completed proof generation on restart. The temp files are gone, so I can't readily do much about that proof cert fail issue.

I've actually found this an interesting study in just how much can be communicated with oneword answers. How short can the word be? How important is the surrounding punctuation? Sorry... I'm Canadian... Eh?

UncWilly again believed it was my fault because another user got a suspected PRP result on an exponent I guessed.
I failed once a little longer than a month ago, Dobri did it too, the application should reserve the temp files until certified. The 1 word "Trumpet" seems to have the most influence among the modern society. Last fiddled with by tuckerkao on 20211215 at 02:14

Here we go again
User "for you" just submitted 3 TF assignments that have no factors with one of them between 2^127 and 2^1024 bits and the other 2 between 2^75 to 2^128 and 2^80 to 2^128 respectively.

Yep. It's been discussed on multiple threads. I expect server or firewall countermeasures are being implemented, as well as database repair and possibly other actions. Perhaps new userid holders would think twice about such misbehavior if signing up required a lump of cash security placed in escrow in the MRI bank account, forfeit for such activity, and perhaps some personal identification provided & verified.
Server problems thread beginning at https://mersenneforum.org/showpost.p...postcount=2419 Massive new mover on Top Producers list (glitch!)  patched thread https://mersenneforum.org/showthread.php?t=27391&page=2 I doubt he had assignments, because the variety of bit levels range from trivially low to absurdly unachievably high. And https://www.mersenne.org/manual_gpu_assignment/ does not go above 85 bits. He pretty clearly submitted forged result records.

I wonder how one does TF 2^{1} to 2^{80} in a single report, as by Roland Clarkson for M217656493, M217652731 and others. And why not from 2^{70} to 2^{80}, since it had already been done to 2^{70}.

The user has a good record with LL and PRP tests and a reasonable rate of success with TF and a very good one rate with P1. Last fiddled with by S485122 on 20220204 at 20:49 Reason: trying to be clear
