If you care to look at the "Recent Cleared" Primenet page, you´ll notice that the last 1000 results are fitting in 8 mins (11:50 - 11:58 AM), rather than the usual 24+ hours. This wouldn´t be a bad thing if it weren´t for the results checked-in: tiny factors from a large part of the whole Primenet range. The credit given is nil, which I think means the result wasn´t expected/needed, I´m not entirely sure.
All in all, this appears to be a pretty useless exercise, that is just cluttering the server. We used to be warned not to submit to many results at a time, but this situation is beyond anything I´d already seen. This user has been pretty hectic over the last few days, spilling heaps of factors on the server pages.
Anything that should be done about it, or is the server currently prepared to accept whatever quantity of results, near simultaneously, without hindering/disrupting its operation? If that´s the case, TJAOI´s works will be no issue.

Ooops, just noticed I posted to the wrong subforum! Would some moderator care to move the thread to the "Primenet" subforum, please?

The exponents are kind of erratic (vs being in ascending order). A lot of the results are ~242 which is a bit surprising. Can the GPU TF software even factor that low? I've heard before that people would only look for factors and not submit any actual results if no factors were found. My guess is these are not the first factors of those exponents.

If you look him up in the TF rankings, he's 1508 with 15 GHz days and 18065 successes out of 18073 attempts, so he at least has the decency to not submit all his no-factor results. I've submitted results in 40 KB batches before (doing 266 in the ~400M range) and while the server is processing them, the rest of the web site is completely useless, so at this point he isn't submitting the no-factors results because the website is functioning normally.

The 0.000 GHz-Days might actually just be rounded from a hyper tiny number because TF to 43 bits is extremely cheap.


If nobody notices the server being bogged down, I don't really care what he does, personally.

I agree. The point is just whether or not this is affecting the server.
The exponents he´s providing factors to were already factored, and I don´t think a GPU is being used. As for the credit, you´re probably right, it´s too small to even show up.
Oh, well...

The server will be affected only for the duration of the submission process. I occasionally work on low factoring limits on the upper scale of things just because I feel like it at the time, and the ~600 line results files I submit take maybe twenty seconds. If it takes noticeably longer, it's because someone else is using the server and I just wait a bit before submitting more.

Like you said - as long as he isn't hurting anyone - he's only wasting his own time filtering through hundreds of thousands of results lines for the factor found ones (if he starts submitting no-factor results, people will start to notice the server slowing down) for clearing no new exponents. In the time it took him to submit all that, my GPU would have made his combined TF credit ten times over, so he's really just wasting time.

No. It starts at 64 right now. At least his results were sorted nicely.

My guess would be some kind of seiving rather than factoring because the factors are so close together.

He is searching "by k" (as opposed to "by p" we do on GIMPS). There should be a thread here around where we used to post pari lines, I think he found one of those.

I've noticed this happening again. Recent cleared is flooded with his factors. He's now up to 817th place with 78 GHz-Days and 87,670 / 87,689.

He's making ~3 GHz. I haven't noticed any damage, personally.

20,000 more in the last 24 hours.

Any concerns, yet?

Edit: He's "discovered" 1/3 of the factors of the last year in less than one month. At this rate (which I said was 3GHz yesterday and is 4GHz today) he'll have flooded the server with six times more factors than the rest of the trial factoring crew combined.
