[QUOTE=Madpoo;487720]Since adding PRP to the site, I hope folks appreciate that adding a new feature like that and then going back through and fixing all kinds of reports behind the scenes is one of those things with lots of moving parts. Personally I didn't really mind thinking that it would be done here and there as time permitted. Y'all are just impatient. LOL[/QUOTE]

This might not be PRP related though.

It is undercounting the number of factored exponents in the 77M range by one (35812 instead of 35813). So that should be old SQL code, which is giving the wrong answer for some reason.

[QUOTE=S485122;487442]The [url=https://www.mersenne.org/report_exponent/?exp_lo=77000000&exp_hi=77000100&text=1]Detailed report / Exponent status[/url] is not outputing correctly in text-only format : when pasted the lines are missing an end of line character. One can use the text-only report if one goes through "view source". I abandoned the idea of doing this 56 times :-([/QUOTE]You may be better served with the "simple" exponent report instead, which outputs pure text:

The missing factored exponent is a fact and might be a clue to the cause of the problems..

[QUOTE=S485122;487777]Indeed that query works ! Thanks ! Since it is limited to 100 exponents, it will not help finding where the problems are.[/QUOTE]I have cleaned up the report code, and increased the report limit from 100 to 1000. I even added a modicum of documentation:

Problem solved, apparently, or at least it went away.

Do we have any insight as to which exponent was stuck on NO-LL ?

I finally dug down into it. After chasing a few rabbit trails that went nowhere, the answer was surprisingly simple. The prime in that range was never removed from a table that holds the "factoring effort" of each exponent. Why that matters? Because that table is actually used to derive the # of factored exponents in a range. Apparently it's slightly quicker to do it that way than to actually look at the factor table.

Anyway, it threw it all off by one. Removed it and... fixed.

As a bonus, I did update that page to show the header lines every 50M instead of every 100M. On my 1920x1080 screen that means you're basically going to see a header row somewhere on the page when scrolling. :smile:

[STRIKE]The server seems to be down.[/STRIKE] It's back up.

[QUOTE=ramgeis;487273]No, I manually submitted the results done by Prime95 from a machine with no connection to the outside world.
Of course I can delete my assignment, but that doesn't make the problem go away.
I just wanted to raise the awareness of an issue on the server side.
I'll definitely have a look at it again when I submit the next results...[/QUOTE]

Another observation: they also don't show up in the recent cleared exponents report [URL]https://www.mersenne.org/report_recent_cleared/[/URL]
I do get credit for the result though - although it does not show up in the summary table at the end of the page after the manual submission.

PRP testing now shows up in that report. It displays cofactor PRP testing too, maybe it shouldn't.

lycorn 2018-06-05 12:07

That´s right.
I think all those inconclusive PRP tests should appear in the "Recent Results" report instead.
