I have a Generfer22 task that is currently estimating 76 days to completion. This is long after the deadline but at the current rate of progress it will still take over 40 days on a Ryzen7 machine. Is this particular task non-linier in its progress? I have come across tasks for other projects where the % complete is not linier with respect to elapsed time.

Deadline will automatically extend up to 84 days as long as you keep contacting the server.

I have not tried those tasks myself, but from what I understand, they really do take that long. PrimeGrid preferences says recent average CPU time is 1128 hours (= 47 days). Most people only run these on GPU.

The tasks are linear.

When I enabled CPU tasks for GFN22, I was under the mistaken impression that the new multithreaded Genefer worked for all Ns. It doesn't. It only works for 21.

Enabling it was a mistake, and deadlines are going to be a problem on all but the fastest CPUs.

Thanks both. I am quite new to Prime Grid so despite being a moderator over at Climate Prediction I clearly have a lot to learn. It still isn't as long as the old days with CPDN where tasks could take nine months to complete on the admittedly much slower cpu's of the time.
