[QUOTE=LaurV;434801]Yeah! Nice milestone! :tu:
Now we only have to find 21 million more factors, to have "less than a million left!" ...
:razz:[/QUOTE]I want to see "less than 49 left".

[size=1]We [u]can[/u] factor those primes, just work harder![/size]

Do you mean there is no prime left? And we work here in vain? :tantrum:
You know, yesterday when people were discussing in a parallel thread, about the largest mersenne full factored, I was thinking, "what the hack, that is 2[SUP]74,207,281[/SUP]−1, and I can't see you finding a larger one too soon..." :cmd:
But no time to post it...

[QUOTE=LaurV;434803]Do you mean there is no prime left? And we work here in vain?[/QUOTE]Yes, we work here in vain. But I don't see how that relates to primes in any way? :razz:

And besides, if/when a new prime is found just keep doing TF until you [url=http://www.quotesnpictures.com/an-easy-way-to-factor-large-prime-numbers/]find that factor[/url].

Expires in minus 42 days.
 
Should we read this as T minus 42?

Ah, yeah, I need to update the calculation for days-to-expire with the new assignment rules. I figured it was a matter of time before something weird happened.

Okay... it's kind of fixed.

This particular one was originally cat 2, but the new expiration rules say it doesn't fall under the expiration guidelines until it's *midway* in the cat 1 category. That was the tricky bit because my code was using the old rules of when it was simply in the cat 1 range at all.

So I adjusted for that and also implemented the other new rules for how many days are allowed, etc. Now it's showing the expiration as null since it's not under any particular countdown for the moment. It's 142 days old or something and according to the old rules it should have expired 22 days ago (at 120 days). But since the new rule only kicks in for "midway in category 1" it's still above that threshold where the clock really starts ticking.

There are some edge cases I'm not accounting for in these calculations (like exceptions for manually assigned work or if the cpu hasn't reported in recently, but I'm okay with that for now. :smile:

How do I adjust my settings so I just get Cat 4 double checks? My exponents to be tested were fine yesterday with respect to expiration, but now three of them are showing that they will expire before being finished. I'm tired of dealing with shifting exponents between computers to avoid expiration so I want the maximum time available.

LOL... it's all good. Besides, I was happy when I paid more attention to the new rules to see all of the "must start within XX days" requirements. Those are good requirements and it lit up the assignment report page like a Christmas tree with all of the red and yellow "about to expire" assignments that weren't highlighted previously. :smile:

Hmm... you can at least ensure that you'll only get cat 3 or cat 4 assignments if you tell Prime95 to get more than 10 days of work at a time.

When you look at that option now, what is it set to?

If I'm guessing your Prime95 username correctly (is it also "richs"?) then it looks like you have 14 active assignments and one additional that expired on May 20. Of the active, 3 of them indeed show that they're category 1 now and were category 3 when assigned back in January. 3 different machines I think?

If that's the case, I guess these must be some older machines if it takes 4+ months to finish a test in the 37M range. I peeked at what the server is reporting for your CPUs and except for a Pentium 4 @ 2.8 GHz, the other 2 seem like they should be running a little faster. The rolling averages for all 3 are well below 1000 so it makes me think they're not running 24/7, or something else on there is CPU hungry?

You can probably get more speed out of it by having 2 cores on one worker instead of one core each for 2 workers (for your i3 and i7 cpus).

Anyway, at least from what I can tell, you're in no danger of getting cat 0/1/2 exponents just based on the performance aspect alone, but you would get cat 3. Even then, cat 3 has 240 days to complete... a solid 8 months of time should be enough, shouldn't it?

The assignment rules say you'll get cat 3 if the computer has enough recent GHz-days to indicate it could probably finish in 90 days. But those rules kicked in *after* those oldest assignments. The newer assignments would have been under the rules but those were cat 3 that are now cat 2... I guess that's the risk there is that you might get the lowest cat 3 stuff and then it could become cat 2 the very next day... you never know. But the expiration rule won't kick in until it's midway into cat 1 territory.

I hope that sheds a little bit of light (and may have useful info for anyone else out there in the same predicament).

Oh, FYI, I looked at the 3 assignments that are now cat 1, and they're not yet below the midway point of cat 1 so the expiration rules don't apply yet. The assignment page should reflect that fact, now that I fixed how expirations are calculated. Check your assignments again and you may be pleasantly surprised that there's no expiration countdown yet.

Shouldn't users be able to know from day 1 the amount of time they have to complete the assignment? All the uncertainty about when things expire is disappointing.
