Default Excessive hording of P-1 factoring assignments (and people's attention)

I was looking at the active exponents, and in particular the P-1 factoring assignments. User "Lisander Viaene" has completed 12 P-1 factoring assignments in the last year
https://www.mersenne.org/report_top_500_p-1/
and contributed 102.621 GHz days of P-1. All very useful.

However, that same user has roughly 24 active P-1 assignments
https://www.mersenne.org/assignments...xtf=1&excert=1
with ETAs of between -30 and -36 days (i.e. all later than expected), with the most that any individual assignment has completed is 1.4% of stage 1 - most show no work whatsoever. All are on computer "Desktop", which may or may not be the same machine.

Is this not a bit excessive? These would be category 0 if they were PRP tests, so it does not seem reasonable to me for someone to hog all these, but not really doing any work on them. I'm not suggesting the user is breaking any assignment rules, but do believe there should be rules to prevent this.

I am aware of exponents that have been owned by a user for longer - even seen reports on here of some being years, where rules are not enforced.

First thing. This thread should have been over in PrimeNet or Data, not New to GIMPS It will be moved. Please be cognizant of where you post new threads. Also, try to find an existing thread that is of the same subject before posting a new one.
For example this one: https://www.mersenneforum.org/showthread.php?t=26001
or this one: https://www.mersenneforum.org/showthread.php?t=26655

If you look at these: 104056151, 104056079,and 104055901 you will see that someone is going in and liberating those that Lisander has in their clutches. It appears that that person is working from the lower exponents upward. If someone else (such as you) worked from the higher downward, or found other such exponents that are being tied up with no work being done on them, that could help clear this problem until the the powers that be fix the assignments rules WRT P-1.

IMHO, no more excessive than polluting the bandwidth of the forum supporting the project with posts with SNR approaching zero.

At least the former can be managed by "sharpshooters" bringing kit to bear to eliminate the problem (AKA strategic poaching).

The latter problem takes more effort to manage. (And patience; much like educating a young and inexperienced mind which demands constant attention.)

That also comes with observation over time and wisdom and insight. One might even stumble across this thread.

That takes reading and diligent observation and self-study of 'prior art'. It should no longer surprise me that technicians often grok the problem space much better than those that choose to add more letters to their name. A former coworker had a 4 year degree in (IIRC) physics and didn't understand the relationship of volts and amps and ohms. I used the water analogy to explain it. They also did not understand that running the heater in their car has no practical effect on fuel economy. They would arrive sometimes bundled up like a 6 year-old in Moscow waiting for the school bus

You can lead a horse to water, but a pencil must be lead.

Is someone liberating them, or are they perhaps expiring? All those you point to were assigned the same date (2021-05-16) as those I see, but those you point to were expired today. The only thing that is odd is that they expired after 37 days, which is a bit of an unusual number.

I'm not going to poach them.

O.M.G.

I don't think I've ever encountered a lower level of comprehension and analytic capability in an entity. Except, of course, for trolls, who do it deliberately.

P-1 on exponent E is assigned to user L.

Little or nothing happens. For weeks or months.

People notice.
P-1 for exponent E is run to completion by some other user T, and a result submitted to the PrimeNet server.
The server enters the P-1 result for E from T into the database, notices the bounds are sufficient for E, retires the P-1 task for that exponent E as completed, and marks any pending P-1 assignment for that exponent E as expired in the database, in this case user L's stagnant P-1 assignment for E, since it's no longer needed.
Subsequent review of the exponent E on the web page will show, T's P-1 result submission for E, and expiration of L's P-1 assignment for E, occurred on the same day.

Thanks for confirming my fears. And to be pedantic, you didn't define the STDOUT for the command, so it will throw an error. Perhaps you meant cat instead of cp?

And that the PRP for exponent E has been assigned to user B. User B complete PRP, server assigns Cert run to user C. User C completes C run and the exponent is marked in the database as Verified.

Rando forumite D is too busy to thoroughly examine exponent status page that has been linked to, thus wasting other forumites K, C, and U's time.
