Max, GB4000 may have had a slight problem.

Earlier today I posted finding a confirmed prime 861*2^572599-1.

It has not posted yet on your stats page or on the Primes found page.

I did find it on yesterday's log just before the daily cleanup.

Ah-ha! I think I know what caused that problem. The copy-off script runs at 6:59 AM CST daily, and the status page script (which handles keeping track of primes) runs every 15 minutes. However, the way it's set up, when it does its run for 7:00 AM (actually, it runs at 7:01 AM), it runs *after* the copy-off script has essentially blanked out the files it works with. Hence, it will miss any prime that just happens to be found between 6:45 AM and 6:59 AM.

I'll go and fix this shortly so that the copy-off script doesn't run until *after* the status page script has had a chance to run. I'll also retroactively add the missed prime into the recurring log of primes.

Okay, I've fixed the crontab so that the status page script runs at every :00, :15, and :45 of every hour, and the copy-off script runs at 7:01 AM. That should close the gap. I'll fix the primes list shortly...

Nice job. I figured it had something to do with the turnover. I just didn't want anyone to miss a prime. Aren't 'puters fun?

Max,

Please load some more pairs in port 4000 within a day or so. I think we had calculated that Ian/you were processing 4200 pairs/day there so loading ~30000 pairs or an n=3K range, which would take 7-8 days, would be a good amount for now.

We should probably also send a file to David for port 400 within 1-2 days too. At about 8000 pairs/day, we could send about an n=5K file on it for the time being.

Okay, yep. I'll do that within the next few hours.

I've given him lots of code, but haven't heard back from Carlos and, I'm not sure he has a web presence.
I can work something up over here for him, it will just be delayed by at least a day's worth of work.

Max,

I noticed that http://nplb-gb1.no-ip.org/llrnet/ is down at the moment so not only can we not view the status of port 4000, I can't access any of my machines remotely. I hope the machine that the server is on is not down. I checked my k/n pairs per hour on port 400 and it appears that there might have been a drop of one quad a few hours ago...Or it could be just some processing glitch in something. I'm not sure. (BTW, I added 2 more cores to port 4000 on Thurs. afternoon after my Riesel base 256 effort finished early Thurs. morning.)

I think I have the temps regulated pretty well on my machines now but unfortunately "crunchford", the machine that runs the server, is still one of the warmer running ones. (~70-71 C I think.) You might remember me mentioning that it was not one of the best choices for the server.

When you get a chance this morning, can you check things and make sure that you can get back on the above link and that port 4000 is working OK? I likely will be on next around 1 PM CST. (7 PM GMT)

Ian, you might also check and make sure you're still processing work on port 4000.


Thanks,
Gary
