My second computer is now logged in and working on an assignment. Can admins tell if I correctly added manual assignments to my queue? I inadvertently started work on a PRP file before I figured out how to add a DC file manually. Did I do everything correctly?

Looking at the assignments in the trailing edge of the DC range:
https://www.mersenne.org/assignments...cm=1&exfirst=1 Over 280 of them have no expiry date. Of those 1 is from >2 years ago. 20 are from 2019 34 are from the first half of 2020. And of those the average ETA is 103 days. (1 is 1473 days and another is 1605 days) 88 are assigned to Anon in some form. What good are assignment rules if they are not applied?

I'd suspect they're all Cat 24 assignments. Cat 24 assignment recycling isn't forced until the exponent is halfway into the Cat 1 range  it looks to me as if that probably explains most or all of these exceptions? I think they will all be forcibly released in due course. Maybe that's a bit lenient, but I think it probably works.

He means the category they were at assignment, which is what determines when they expire, not the category they have now:
54854537 Cat 4 https://www.mersenne.org/thresholds/?dt=20181123 54745991 Cat 4 https://www.mersenne.org/thresholds/?dt=20190129 etc. The lowest 54M exponents entered Cat 3 on Oct 28th 2019: https://www.mersenne.org/thresholds/?dt=20191028 So Cat3+4 will expire after 240/360 days but not before halfway through Cat1 which is around: https://www.mersenne.org/thresholds/ (54276248+55157660)/2 = 54716954 which agrees with the fact that the lowest old exponent is 54745991. Maybe it should be changed to when they enter Cat 1 (if above 240/360 days). Last fiddled with by ATH on 20201218 at 06:53

2) What is meant by "midway into"? I always understood it like "while still in the ongoing computation from this assignment it reaches the 'first category'" which would mean the upper edge of that. But from ATH's answer, I see an argument for the exponent at the halfway point in that cat. 3) Is there any meaning in "as little as"? This wording is not contained in the Cats 0 and 1. Is there any difference? Can someone elaborate or push me to a thread where this was discussed? TIA

At the moment there is a problem with the rules : the rule "must be completed in as little (within) 360 days" is not enforced, assignments are only recycled when they are older than 360 days and the exponent enters CAT 1. Another thing wrong with the rules is that they are only applied to LL/DC/PRP/PRP_CERT assignments. Which means TF or PM1 can squat in the lower categories. A better wording of the rule as implemented could be : Quote:

From my perspective, there is still ambiguity in your proposal which is never good for rules: Quote:
Maybe this page needs some updates and concretization.

2) Midway into means halfway between cat 1 and cat 2. 3) As little as means you'll always get a minimum of 240/360 days for cat 3/4. You might get more time if it takes more than 240/360 days for your exponent to reach the "halfway between cat 1 and 2" boundary. Assignment rules are a balancing act between timely progression of milestones and not wasting work when a slow user could have returned a result if given more time. The readers of this thread are strongly weighted to seeing milestones progress as quickly as possible whereas GIMPS throughput is maximized when as little work as possible is wasted by exponent recycling. That said, I do not monitor this balancing act. Perhaps some minor tweaking of the rules is warranted.

A question how come M54113743 hasn't been recycled. It was assigned on 20201103, it was category 0 at assignment time, it hasn't been reported reported about since 20 days, is more than 30 days old... In my understanding it should have been recycled on 20201203. Jacob
