Assignments over a year long

TObject · 2012-02-17, 21:47

I got the following message:

WARNING: Estimated completion date is more than one year away. The assignment may be reassigned to another user after one year.

Should I release the assignment and get something else? I do not mind long assignments, but I do not want to do a whole year worth of crunching just to throw it away (it is an LL assignment, so if I understand the algorithm correctly the new user who may get my assignment will not be able to use my intermediate results and will have to start from the beginning).

As long as the computer sends periodic updates to the server, what is the point of taking the assignment away and giving it to somebody else?

That's the LL-100M-digits worktype we told you about in the other thread. At this point, the LL wavefront is around 58M -- the first expo with 100 million digits is in the 332M range. If it gets unassigned (big if, there's no reason to unassign it) it will not be assigned again, mostly because very few people do that worktype, and even less ever actually finish the assignment. When's the completion date -- 2013, or past 2015? If it's the latter, you should switch worktypes to something less ridiculous. (Consider this: only 1 LL test has ever been completed in that range, ever.)

Assignments can be extended through PrimeNet at-
http://www.mersenne.org/manual_extension/

If this assignment came through GPU to 72, you can also extend it on your Assignments page.

This must be quite a large exponent.

The completion is in 2016. It is not unreasonable. The server is new, and the server it replaced worked for nine years.

Thanks. That will work.

Is there a list of all these hidden web site pages somewhere?

All the PrimeNet pages are listed on the left side. If you click on the plus next to "Manual Testing" you will find the same link. (Keep in mind that in 2016 we will probably have hardware that can do the same assignment in a few months -- much the same way as 4 years ago our hardware was again significantly worse.)

Holly molly, those are plusses? I though them were just bullets.

My God—it's full of stars!

ROFLMAO!

I don't know of a master list of cool links. I'm still finding out about all sorts of things after months of active involvement.

"View Assignments" is under "My Account" in GPU to 72. This is where you can extend GPU272 assignments, though for LL primality tests I don't think it matters where you do it there or in PrimeNet.

I invite correction if I am misinforming.

Isn't the manual extension only necessary for offline assignments? If P95 is talking to the server daily/weekly, wouldn't it keep the assignment active, knowing it's in progress?

I'm pretty sure he has no idea what GPU272 is. This is a hundred million digit assignment he's talking about.

@bcp19: P95 will unreserve assignments if PrimeNet thinks it's taking too long. OTOH, since it is a 100M assignment, I don't think he needs to worry about it.

Yeah, the usability (or lack thereof) of the website has been discussed before. Tiny distorted pictures, tiny distorted font and requiring JS to function ... but I guess the maintainers like it that way so we just have to live with it.
