Thanks Curtis,

I hope to get this started in the morning.

If you get a chance before your run, reduce lim1 from 32e6 to 28e6. It won't make much difference, but I believe that smaller lim's reduce matrix size and LA time. Since that's the one part stuck on a single machine, it's worth trading a bit of sieve efficiency to try for a smaller matrix.

It looks like I got the chance. The process got hung up again, as before. Should I add "tasks.polyselect.admin = 1e3" again? I left it out when I rewrote params.c150.

Due to other things, it looks like I'm going to have to wait until Monday to retry...

Sure, that's probably wise for general use on medium-sized inputs (say, C130 or higher). Smaller numbers seem to be more likely to have a best-poly-score on a very small coefficient, so I'd not put that in for numbers below C130.
I set poly work size to 5e2 in part to try to avoid this problem; guess that wasn't enough.

The C130 work ran without the issue. I don't think I tried any C140 work. I've added it now for the C150, but it won't run until at least Monday.

I started the run at pretty close to 10:00 local, but stopped it at a little prior to 11:30 because over a quarter of my machines dropped a client!

I restarted and will see if this happens again.

I have some changes to make to my scripts because I can "see" why temporary terminals fail. Currently, I'm using instances that close on their own when done. I might just add a sleep 1000000 line or log any stderr.

Well done, Curtis,

The results are in and I would have to say you made quite a difference!

My params scored.... half? Really? Half the time? That's nuts. That also means that whatever the CADO people are doing for their automated parameter-generation, it's lousy.

Note that my guess for poly select effort was off by a factor of two; you spent 10% of total job length on poly select rather than 5%. I'll cut admax in half to fix this.
The CADO matrix still took 15 hr, but for overall CPU-time did CADO beat GGNFS?

Edit: If I've got the math right, based on post #173 in this thread the CADO-sieve phase took around 5 hr, beating GGNFS's 8hr handily. Can you confirm? If so, CADO is the package of choice for C150, and I have much inventive to create params files for 135-160.

:bow:

Here are the logs for the msieve/ggnfs run. Keep in mind I hard stopped the poly select at five minutes.

[/code]Note, that, although it doesn't affect the cado-nfs vs. msieve/ggnfs results, I'm just a little concerned about my initial cado-nfs run with default params. I might have missed it, if any clients dropped out, since I wasn't looking for it at that time.

This would only affect wall-clock time, not the CPU-time that we're mainly using for comparison. Most of the wall-clock time is eaten by the matrix, so a few clients disappearing during the sieve phase shouldn't matter much.

I set CADO to use 29/30-bit large primes, and your run used 72M raw relations to build the matrix. That doesn't sound massively higher than my recollection of msieve at this size, so perhaps my claim that CADO filtering is a hindrance is mistaken.
I'll dig up some C150 tasks and give this GGNFS vs CADO comparison a shot myself sometime soon.
