Perhaps since it would be a very short job by f-small standards we might get to skip ahead of a couple other jobs and have both halves of the sieving done by early July.

I’m willing to let this effort go to the front of f-small queue, but we need to hear the same from Robert and Oliver.

Shouldn’t take long to run ~half a sieving job.

If you mean L1636, no worries, that's also your baby. It has no hurry from my point of view.
Personally, I would put it directly after 822__457^17-1, but this is only my opinion.

Speaking about it, I would like to take 822__457^17-1 after my good experience with larger matrices on my GPUs. I can put this in the according thread, additionally, but maybe we can save a post this way.

Yeah, go ahead.

[swellman]

Thank you gentlemen. We will enqueue the new effort once it is posted. Shouldn’t take that much time to complete.

Of course, I’ll reserve the LA in your name. Good luck!

I've not heard of the option you're experimenting with, and I am quite curious.

My aim was to increase yield/sec by increasing yield. My experiments have just about broken even.

which looks like it is probably better on the benefit/difficulty scale than other very high count numbers, although I make be underestimating how bad the quartic will be. Would this fit in 16e_small?

I have this quartic sieving on a public-facing CADO server. As with the old 2330L Cunningham job from a couple years ago, I do not wish to publish the server address on a public forum. Please PM me for the server address.

Your cado client command will be: ./cado-nfs-client.py --bindir=build/{whatever folder lives in your build directory, usually the computer name] --server=http://{servername}

The default is 4-threaded sieving, meaning each client you invoke will run 4-threaded. You can run multiple clients from the same CADO directory, just one per terminal window.... or you can set the number of threads yourself by adding "--override t n" to the end of your client command, with n set to the number of threads you like.

I have 5 sievers running on the host, and one client running from home.

I am planning on 450M raw relations locally, and 475-500M from nfs@home 16e. Both test-sieve with yield around 5, so this will be roughly Q=50-140M locally and Q=175-275M on nfs@home.
