results not needed

By the time I got my shoes on, figured out appropriate time-exposure settings on my camera, mounted it on the tripod, and got it outside, the moon was just a bright smudge, again.

At 11:40 PM CDT, I can see a nice, completely full moon out the window.

In Buenos Aires there were no clouds, and I was able to see the first half of the lunar eclipse until 12 AM local time (3AM UTC) including the red phase. There were some shows in TV in which they showed the Moon through telescopes during about 5 hs so all phases of the Eclipse could be seen.

Madpoo, please transfer the credit as appropriate if it's not too much trouble.

Now, back to the eclipse (it's spectacular!!!)

If anyone had their assignment "poached" (but not really), holler at me and I'll figure out what goes where. If you check in your work as a triple-check, it'll say it was for an already verified exponent but you'll still get credit. In fact, I *think* that might be true for assigned TF work as well.

Heck, you'll even get credit for turning in an LL result on a factored exponent, as long as you had a valid assignment id, just out of pity for the work put in. LOL

A bit strange are the results anyway (same for both exponents):
User "Guido Lorenzini" reported "no factor from 2⁷³ to 2⁷⁴" and "no factor from 2⁷⁴ to 2⁷⁵" on 2015-09-17 and than reported factors within exactly that range on 2015-09-25.

Hi Oliver. This is Guido writing.
I've experimented some iussue in the recent past with my GPUs. I immediately thought this was due to the overclock. (I had some PMs with Chris about that). So I've reset the GPUs freqs to the stock level. But this wasn't enough. The Nvidia driver was still crashing randomly while Mfaktc's running. These crashes were even more frequent when I was trying to run CudaLucas [even if the error checks were reasonably low (0,012)] (This is why I've decided to abandon my efforts with Cudalucas). So I've start checking between each GPU. I think I've found the guilty and removed it from the search. The results you've noticed are due to the fact that I've rerunned some tests when I saw something weird but, onestly my checks are absolutely not sistematic. Hope thing are going well now and my results are reasonably reliable. I'm really sorry for any problem I've caused to GIMPS.

Hi all!
As suggested to me by Chris I'm pointing out here another weird behaviour I've noticed running Misfit. I was reluctanct in doing this. I was afraid to look like a moron since I was overclocking my hardware and, above all, I'm not able to give more specific infos...
Some time ago I switched between GPU72 and Primenet as source for my assignements (I was "frustraded" because I was finding so few factors at these relative high fact bit levels...). Misfit was set to balance it as soon as the difference in the workload between my 5 GPUs was more than 6 exps (this is because 4 GPUs are quite fast and one is much slower: 7/800 Ghz vs 150 GHz/day). Well, I don't know why but, after that swiching I found in my misfit_worktodo file quite weird assignements: some were duplicates, some were already factored, finally some were mismatching with GPU72 ones. As suggested by Chris, I've completely erased all of my worktodo files, re-downloaded a new worktodo file from GPU72 and restarted everything... By now I do not have yet exactely understand what happened...

[VictordeHolland]

Would it be possible to find out all the assignments that specific GPU did so we (the community) can recheck them?

[guido72]

Unfortunately no. I set the saving period for log files to 60 days in Misfit just after the troubles: I may say wich GPU has done what with specific timestamp right now... but no info for the recent past. Anyway: just 2000 results or something has been credited to me in the last two months...
I'm still getting this from "Al"

This is just an excerpt. I've got a couple of dozen of these messages recentely...

Everything seem to work properly here (I mean my hw...) right now...

Hi Guido,

good to know the reason. Thank you for clearing up the situation.

In my opinion, the most important thing a technical / scientific person can do is to share what they observe, and be willing to admit they might have done things sub-optimally based on counter evidence and/or argument (but they should fight like heck if they think they're correct).

The best thing that will happen is they're proven correct. The worst is they're proven wrong and/or they made a mistake; and thus they learn.

This why I enjoy the Sciences so much; it often takes thick skin, but everyone benefits at the end of the day.

Actually Yes... In the MISFITBackups directory there is a file for every results.txt exported and the filename is the path to the GPU instance

this file
BACKUP_RESULTS_EXPORTED_D-os_shared_root-GIMPS-TF-MFAKTC-Results.txt_130855415262115913_fa30fa1e

came from
D:\OS_SHARED_ROOT\GIMPS\TF\MFAKTC

Thanks
