I started running PSP LLR on a couple of old computers. One of these is an AMD Sempron 3000+. Until the last WU, all of the n's were in the 3M range, and these were finishing in around 60 hours, roughly four times the PrimeGrid average (which is normal for that computer.)

The most recent WU is in the 9M range, and is running roughly four times slower, about 2 hours per one percent complete.

That's roughly 200 hours,which is 32 hours longer than the 7 day deadline.

So, the first question is, should I abort this or let it complete? Even though I'll miss the deadline, I suspect I'll still finish soon enough to get credit.

Second, is it normal for this range of 'n' to take that much longer to compute? If so, might I suggest that WUs with higher range n's receive longer deadlines? If it takes 2.5 days for an average computer to computer this WU, then half of the machines out there (the ones below the average) are going to have deadline issues.

The most recent WU is in the 9M range, and is running roughly four times slower, about 2 hours per one percent complete.

That's roughly 200 hours,which is 32 hours longer than the 7 day deadline.

So, the first question is, should I abort this or let it complete? Even though I'll miss the deadline, I suspect I'll still finish soon enough to get credit.

That's a tough call. I would lean on the side of letting it complete. Hopefully it will come in soon enough after the deadline to cancel the other outgoing WU.

Deadline for the DC effort was dropped to 1 week to help with processing. This was fine for the n<5M range. However, it appears that 5M<n<6M would have benefited from an increase to 10 days. 9M WU's have a deadline of 14 days...so yes, deadlines are increased periodically to compensate for the longer WU's.

EDIT: %$#@% We forgot to edit the deadline in the last 9M batch. Therefore, yes, they will have 7 day deadlines (about 440 WU's). :( We apologize. It has been corrected for the next update.

The WU you link to above is actually 5.99M, at the highest end of the DC effort. Therefore, hopefully there won't be too many of these instances.

I think I linked the WU from the wrong computer. This WU should be the correct one. Then again, I'm doing this from my phone, so the link may go anywhere. Bagpipe lessons, anybody?

Yes, that is one of the 440 WU's that made it out.

Yea, just finished this about half an hour ago! The computer did take a 24 hour break to participate in the Ides of March challenge, but otherwise has been crunching 24/7 on this WU.
