Mine says "GCD in progress... this may take a few minutes". It doesn't report percentage during that time.

[QUOTE=cheesehead;283567]The GCDs at ends of stage 1 and 2 take several minutes -- might one have been in progress?[/QUOTE]

Nope; it spent at least 10 minutes on 100% of Stage 2 ; then the GCD kicked in.

This bug has never been fixed. It's not reproducible and I've examined the code several times and cannot figure out how it happens.

Factor
 
M52038281 has a factor:

23,156,409,264,727,587,094,789,739,703,316,217

[URL]http://mersenne-aries.sili.net/exponent.php?exponentdetails=52038281[/URL]

P-1 found a factor in stage #2, B1=505000, B2=10352500

Looks like something is up with that K value on James' website.

[QUOTE=KyleAskine;283725]Looks like something is up with that K value on James' website.[/QUOTE]There is, I noticed that just now when [i]flashjh[/i] posted his factor. I need to look at that tomorrow. B1/B2 are accurate though.

Have you tried telling Prime95 to report the completion percentage to four or even six decimal places? What might be happening is that anything above 99.9xxx% is being reported as 100.00%. Or, if the assignment is within x minutes of the ETA, Prime95 simply rounds off the completion percentage to 100.

IIRC, the percentage is always rounded down.

Looking through my stuff on the site, and I found this:
[url]http://mersenne-aries.sili.net/exponent.php?exponentdetails=52389509[/url]
[url]http://mersenne-aries.sili.net/exponent.php?exponentdetails=48104261[/url]
These are my only two results.

Huh. For the second, it displays correctly if you go the factor page, rather than the exponent page:
[url]http://mersenne-aries.sili.net/exponent.php?factordetails=1574475018803497078755023[/url]

And now suddenly the first one works fine from either page. And so does the second. Did I catch this right as you fixed it?

[QUOTE=KyleAskine;283725]Looks like something is up with that K value on James' website.[/QUOTE]And it's fixed now.

edit: I probably broke whatever [i]Dubslow[/i] was looking at while he was looking at it, and created confusion. :smile:

How does one read these "Show stats for user" pages? I looked up [URL="http://mersenne-aries.sili.net/stats.php?showuserstats=Luigi+Morelli"]Luigi's[/URL] info, and it says that he's done 8 TFs, 3 P-1's, and no LLs, and then only since December 25 -- whereas in fact we know he's done a lot more than that, for a much longer period of time. Whereas if you look up [URL="http://mersenne-aries.sili.net/stats.php?showuserstats=Dubslow"]Dubslow's[/URL] page, it seems to provide much more realistic-looking (but still incomplete, going back to July) figures and timeframes for exponents processed.
