Thanks richD. I became impatient with my server that was stuck, so I restarted it to gather more relations for my msieve run. This was done partly because I can't get any of my other machines to...

Well, . . . My server finally declared it had enough relations at 274402507 and told all the clients to, "Knock it off!"

Unfortunately, it then proceeded to get memory stuck using 99.8% of 15.6...

I got back 31k relations from my first sieve run in my Colab instance and was able to get those added to the msieve parallel run. Hopefully, that will help with the matrix build.

However, I was...

Thanks, Xyzzy!

So, they must be decompressed first. I've been "cat"ing the .gz files into a composite for msieve, which has no trouble with the relations being compressed. I will play with this...

I have run into a problem that I already have here, but work around:

When I run an snfs job, the server doesn't start any local sievers. Here, I separately start some on the server machine, but I...

I am working on a Colab Instance of CADO-NFS to pick up the 100k-150k section of relations of a current snfs run. (I hope to eventually document my adventure in my "How I . . ." threads.)

Although my most recent update isn't that old, tasks.A is not recognized and none of my clients are newer than the newest server. It would be quite a task to update all of them.

I "think" I understand this point. I must study it a bit more.

As an aside, looking at a random machine, I find that it returned in 15:05 with 28074 relations early on. The last iteration took...

Well, I've added 10M more relations in the last 6.5 hours, so maybe the return isn't as bad as I thought. But, OTOH, msieve knocked them all down to the same 2382 relations by the end.

Since the relations being returned have fallen from over 25k to ~6k per WU, doesn't that become about 1/6th done relative to time? At 4+ days in, that means quite a bit longer before I can even...

If it is of interest, I have a high rate of duplication:
