Anyone have some suitable jobs for 14e? It’s going to run dry by the weekend. Please don’t rush any jobs - I see there are a few GNFS polys currently being optimized so let those bake.

There is a bunch of HCN work in the SNFS 23X (quartic) range, as well as some SNFS 255 (deg 5/6) jobs I was pondering for 14e if no one objects. We’ve been processing GNFS 175-176 with no major issues, so I’m hoping we can explore some SNFS 251-256 jobs as well.

Because these are all 32-bit jobs, a gradual feed into the queue seems proper (e.g. every third or fourth job) to avoid a traffic jam in postprocessing.

Many thanks to charybdis for the poly, even though it took a while to test sieve them all enough to be sure I had found the best.

Chris

PS. I should be able to test sieve another number by tomorrow.

I will take a temporary break from post-processing and devote those resources to the final lap of ECM curves for a bunch of smallish (29 & 30 bit) jobs.
