Obviously this job is larger than the recently adopted paradigm allows, with 31bit lpb and lims > 100M. But 14d IS running dry and we do need to feed the pentathlon beast. (Plus I like the idea of your script. Could be easier than appending files and then running remdups.) I’ll enqueue both job files later tonight unless someone objects.

I don't understand why we need to feed 14 at all. I thought the idea was to intentionally let it run dry, only feeding it jobs that are clearly inefficient on 15e; when it's dry, more workunits get done on the other sievers that run jobs we care about / are too hard for singlemachine factorers.
This isn't one of those jobs, to my eye (I didn't test sieve). We have quite a backlog on 15esmall, but a horde of BOINCers might fix that up right quick. There's no reason to try to fill 14e jobs to feed this army the army should simply look to larger sievers. I don't object to running this job as submitted, but I wish to discourage future submitters from using 14 when 15esmall is as efficient for their job.

I know this does nothing to advance the knowledge to move the wavefront forward and upward. But offering a few small numbers here or there to welcome newcomers to be introduced into integer factoring techniques would be beneficial for the generations to come. I'm not sure every BOINCer has 8GB to devote to their 8/10/12 thread box. Just my two cents.

I think the lower bound for esmall is any job that is no slower on 15e than on 14e. Jobs that are clearly faster on 14e should still go there (until the 14e queue disappears entirely, but I think that's a while away).
In practice, there's a small slice of jobs that are pretty long for solo factorers but not faster on 15e something like GNFS 156166 in size (SNFS resists clean size examples). If there aren't any of those to do for some time, we shouldn't try to scare up work the clients should just bounce to the other queues, and esmall client uses very little memory now that we restrict lim's to 134M. My objection to this specific job was poster's admission that he was sending it to 14e solely because of the possible BOINC army, and that it would be faster on 15esmall. He does get to test new scripts, thus my attempt to say "let's not make a habit of this" rather than "let's not do this." Last fiddled with by VBCurtis on 20210501 at 07:36

I won't try to send any more jobs this big to 14e. It may well take twice as long to solve the matrix as it would on 15e_small (using 3LP makes the matrix bigger).
As I said it's only to give the BOINC army something to do. Chris

I havn't enough relations to build a decent matrix, I underestimated how many duplicates it would have. From remdups:
Code:
Found 178553883 unique, 108375842 duplicate (37.8% of total), and 422 bad relations. And I should have timed it to start sieving when/if the BOINC crowd were about to start. Sorry. Chris PS. I'll do f13_227p1 first. So no rush to add relations. Last fiddled with by chris2be8 on 20210505 at 08:08 Reason: Added PS.
