Default Rechecking CUDALucas-only LL results

These are the 74 exponents returned by George's database query for exponents verified using CUDALucas only. They are candidates for independent verification of seed 4 final LL res64 only, using different software; gpuowl, prime95, or mlucas. Perhaps even cllucas, although I would avoid it due to speed and reliability and mainly because it was derived directly from CUDALucas.
Note, these can not be registered with the PrimeNet server.
I interpret ATH's posts as he intended to rerun one, has done so, and the rest are fair game for others, no toes mashed.

So far, 73 matched, no mismatches yet, 1 to go as of mid 2022-12-04 (US CST), of which 1 is not yet queued. Good progress and encouraging results!
I've added [CUDALucas original fft-length estimate] markers based on a pseudorandomly selected fft file from a Quadro 2000 CUDALucas benchmarking run from long ago. [length] divides those preceding, that could have used it, from those following, for which it is expected to be too small. Units are K words. This is only an estimate of how many and which lengths the preceding CUDALucas runs might have involved, since different GPU models benchmarking often select different fft lengths to record in the fft file, or fastest fft lengths may be nonreproducible from one benchmark run to another on the same GPU, or users may force specific lengths. We don't have data on which GPU models were used on specific previous CUDALucas LL runs. Following the length is (estimated count). The point is to estimate coverage of CUDALucas fft lengths.
I count 17 populated estimated lengths (out of 88 in the applicable range in the selected fft benchmark file), of which 16 have at least one completed matched result below, and 16 have all completed. Note 20000K and all other fft lengths suitable for 100Mdigit Mersennes are absent from the list below.


When claiming or updating one or more for this additional checking with anything except CUDALucas, please state which exponent(s), and for each, what application(s) will be used, including what version(s), optionally current status(es) e.g. queued or running, and optionally what ETA(s) when applicable.
Color code below: purple reference; underlined blue links to mersenne.org exponent status, black undetermined, green matched, red mismatch (if any).

I'll do these with P95 30.8b17:
35381377
35478853
36142801
36211067
36313813
36497473
ETA 3 days or so for all.
Finally, something my i9-11900 has something to do!

Everything under 40M, for a start.
gpuOwl 6 (same one compiled by kriesel) Radeon vii, win 7, 2 cards should go through them like cheese.

[Trivia]
As you were kind enough to provide proper links, I played along by clicking on each one you know that saying that every link must be clicked...
What's puzzling here, almost all of them (with only 2-3 exceptions, which were recently tested) have a "bad residue" test sometimes in 2007-2008 (few in or after 2011).
I mean, all, not only those I reserved.
A lot of wasted computing power, at the time...
[/Trivia]


edit (kriesel): Yes, only one below 57M did not have a bad first LL. Many of those are from 2010.
Your link clicking was redundant in a sense. As a former webmaster I am in the habit of testing all links posted. The links were however created for the convenience of all recheck participants or the merely curious.

I don't really think it is needed to check all these with the shift count enabled, and I do not have much resources now that I stopped my Colab accounts.
If there is a bug it is probably only in the 20000K FFT.

If you find something in those you already queued now, I can take a few.

If possible, I would like to take
55831921
56294479
56309111
57766307
for PRP. Or is LL preferred here?

Definitely LL only, since it is the CUDALucas LL final res64 we are attempting to confirm with other software, as an attempt to identify possible fft-length-dependent CUDALucas bugs. CUDALucas is LL only. I've added you to the list in post one for those. What software will you be using?


edit: PRP would only provide confirmation the LL final residue should not be zero, but provide no information about what the LL res64 should be beyond that.

Good to now.

I will use GPUowl, and if those do not match, I will queue them on another machine with mprime/Prime95.

Thank you for the clarification!

Right now I have not yet a fixed version. Do you recommend this version for this project?

Gpuowl V6.11-380 or some versions near it support LL with Jacobi symbol check and are about as fast as available. Gpuowl V7.x omits LL so is not usable for this.
