Dubslow posted a link to the status numerous exponent assignments from 38103407 to 45000000 he put on his site from Jan 11 and Feb 21. In looking at all of the assignments over 365 days old that showed progress and were in both dates, there were 9 that showed no change, 20 that showed .1 to 1% progress, 22 from 1% to 5% and 9 with 5%+. Given that 41 days had passed and x% had completed, I used a spreadsheet to calculate remaining time on these 51 exponents based on those numbers, 32 of these 51 showed between 1 and 98 years remaining:

Poaching status has nothing to do with any reason or blame for unreservation. Poaching is knowingly or carelessly starting or resuming work on an exponent that's assigned to someone else but not to you.

Yes, advocates and apologists for poaching can find and list numerous excuses.

But none of those excuses gives you a PrimeNet assignment. Without an assignment, it's poaching if someone else _does_ have an assignment for that exponent.

Quote:
Communicating with the current assignee is in general not possible; I am sure that many people join GIMPS because of the minimum of interaction required to participate in the project.
Yes, advocates and apologists for poaching like "minimum of interaction", because the less interaction they have, the less they have to think about the effects of their poaching on the real person to whom the exponent is assigned.

Quote:
Communicating with anyone, George/admin or not, is still a hassle, and falls under the "not-minimal-interaction".
Paying for an item at a store is a hassle. It's much more minimal to just walk out of a store after pocketing some item than it is to go through all the hassle of standing in line at a cashier and actually paying for the item.

That doesn't make shoplifting okay, and the aspects you mention don't justify poaching.

It is far easier and simpler just to finish the work that had already been done so that I don't lose two months of work. No one will die.

Well I will willingly be doing that. I told you my situation I have a few exponents where the original assignments were lost. It was completely due to circumstances which I did not have control over. When it has been possible I have registered similar cases as double-checks. The others have been reassinged a number of times since I had them but I can never catch them on the fly myself when they are available.

The exponents concerned are:

M51641341
M52502687
M53045947
M51394979
M52026859
M52834037

So please help me. Who should I communicate with and what should I ask for??

Maybe chalsall can help me with M51394979 since it is reserved for GPU factoring.

So far, due to this discussion, I have disconnected prime95 from PrimeNet so even if they finish the result will not be sent to the server.

... or should I just drop the exponents. They are on average around 70%.

But, empricially, it seems there are only two trust levels with PrimeNet currently.

"Trusted" machines get "prefered" assignments.

Everyone else (including Anonymous machines) get anything above the prefered which are available; including those candidates at the "wave-back".

IMHO, PrimeNet needs some tender loving attention on its heuristics (and a bit of time on the table's indexes probably wouldn't hurt either)....
And some front end work...

I think both of you are right, and both of you are wrong (edit: chalsall-cheesehead dispute, sorry, did not see the last page of the thread). It is not possible to stop poaching. Poaching is happening since GIPMS exists, everyone did it occasionally, even now is going on, and it is simply to prove: if you add the DC assignments in the 30M range with the cleared expos, you get a surplus of about 200 expos. They are poacher's. If you look to active assignments under 24M (there should be NO LL and NO DC, all the range is cleared, according with the last registered milestone), there are still 20 or 30 active assignments. They were poached because the assignee was too slow, or are poached and the poacher is too slow.

Gimps survived for 10 years and poaching was never a big problem. Not all people understand that they are wasting resources if they poach. The most of us do understand, or do not care (they set and forget p95), but still that, sometime the curiosity beat the crap out of us. And we occasionally poach.

Of course this can give birth to unwanted situations, especially if some poacher finds a prime before the assignee does. These cases should be judged FROM CASE TO CASE. You can not make a general rule. Was the assignee sleeping? Had he billions of assignment or a very slow machine? Is the poacher... poacher? Does he do that everyday, or he did it just first/second/etc time? This is all recorded in the database.

All situations can be judged INDIVIDUALLY. You can not make a general rule, like for example "the assignee always take the money and the glory". This would be stupid and could result in abuses, for example I would reserve few thousands exponents and do just so much work on them to avoid Primenet kicking my ass off. Some "poacher" will get bored, and if he would find a prime I would take the money.

We could never interdict poaching by a rule. What you can do? Ban the poacher? You lose the computing power. Of course, we would never encourage poaching by a given rule. Fortunately most of the people understand that poaching is waste of time on their side. We already discussed this in many threads, many times.

And so on. Good/bad examples can be found on both cases.

Here is George view on when assignments are too old, from the previous milestone thread: http://www.mersenneforum.org/showpos...&postcount=443

So if assignment is more than 365 days old and progress<50% or if assignment is more than 548 days old.

Apparently these recycling rules are still not implemented or not working properly, or your example M24077267 would have been reassigned 312 days ago.
