I was looking at this list:
https://www.mersenne.org/assignments...xtf=1&excert=1

And taking those on the trailing end that had the following criteria:
Assigned at least 3 weeks.
Had not checked in recently
Were overdue (negative ETA) or showed zero progress and had ETA's over 20 days.

I last queued up exponents from the list on Friday. The machine that turned in the results was down for 2 days over the weekend to boot and doing some PRP-CF-DCs in between the P-1's.

There are a lot stalled P-1 assignments in that range and no expiration rules in evidence. So, I was doing these P-1's so they can get their PRP's done.
Since you are a known good worker and the exponents showed in the negative ETA (and by my looking over the week before watching for progress), I assumed that the assignment got orphaned or was on an unreachable machine.

It's a computer that I don't use as often as I used to. Perhaps it's time to retire it from GIMPS.

But I would definitely have appreciated it if you gave me a heads-up instead of making assumptions.

Wondering what happened on this LL-D exponent: M56109727
Was there a duplicate assignment?

I believe that AuspiciousLLama's assignment timed out due to inactivity. Then it was reassigned. Then at some point AuspiciousLLama's machine woke up and completed the assignment, or had completed it a while ago but the result had not been reported, but it got reported shortly before the replacement assignment completed.

This can and does happen.

Would assignments that time out still be displayed on the history of assigned and expired assignments for that exponent, or does checking in a result, even late, clear that?

If an assignment times out it will show in the Assigned section in red, including the last check in date which could even be after it has expired. However once it turns in a result it's no longer shown in the assigned section, it'll show as a result, even if it turns in the result after it's expired.

There are some assignments that get turned in years after they've expired.

Understood on the potential for old assignments checking in late. Looking at the Recently Cleared Exponents page, that does seem to be the case. There just wasn't an obvious indication on the individual exponent status pages, while the Recently Cleared Exponents page does show the assignment age.


It's a pity this batch of late results has duplicated a bit of effort (unnecessary triple checks and expiring in progress assignments) with these Cat 1 exponents.

It's an issue with setting hard expiration dates in general. No matter where you set the expiration date, there will be some assignments that complete shortly after the expiration dates. Sometimes assignments that appear to be abandoned resume months later.

In the case of AuspiciousLlama - this account had been doing a large amount of work and turning in results regularly, then suddenly went silent for a period of weeks. Now it's awake again, and turning in a large numbers of assignments, including recently turning in over 20 that had expired within the last couple weeks.

Another poacher : "Borek BOISSY".
Manual assignments only, so he knows what he is doing :-(
Now I should ask him using Facebook, LinkedIn, Twitter or YouTube (he is present there according to a quick internet search. But I don't have an account in any of those antisocial media and I am not sure I would want to contact him.

I'll let my assigned DC complete notwithstanding (it is at about 80% with an ETA of less than two hours.) But it might be time for me to stop doing CAT0 and 1 DC's.

And also wasting cycles on new first LL tests up to 150M as recently as today. Compared to PRP/GEC/Proof & done, a first LL test is a net loss of 100% or more.
If it's LL DC later, there's ~4% chance of needing an LL TC. If the DC is PRP/GEC/proof instead, there may as well not have been an LL first test.

He does some PRP with proof using PrimeNet. His LL work is done outside of PrimeNet... 4 of his 5 DCs are poached. A forum user has offered to contact him, I gladly accepted in a much too long private message.
