Looks like 7-8% slower than the scaling one would expect for a C162 given the timing data from the C165 (that is, using the "double effort every 5.5 digits" heuristic).

I'd expect 3.72...

In principle, it should be possible to get running through the linux-term prompt within win10, but I imagine it's a bear to make that happen. I think you're stuck with the software you've got.

Is this CADO or GGNFS/yafu?

That same Z620 has 8min 20 sec for a C103 and almost exactly 60 min for C120, running CADO with the params files posted to the CADO forum. If you're in Linux, I...

Ed's farm is something like 100 cores spread over a ton of rather old hardware, like HP Z600 age or even some Core2.
His magic is in the scripting to get them all to work together. :)

I think he meant that going to 10k himself would yield something whose next step is better for BOINC. The 5k-10k tests are a little small for BOINC, as you observe. That is, I think you two agree.

R400 is enormous and slow- I broke the k-range into 5 parts. Two of them are done to 10k (up to k=4M), while the other three are done only to 5k and in progress (4-8M, 8-14M, 14-20M).
I didn't...

Second ECM run complete, on the number quoted here.
The third of four in the list was factored by yoyo; I'll work on #4 in a week or so when I finish ECM on 13_2_929m1.

R327 has reached 715k.

3 large prime jobs produce matrices 10-20% larger than jobs with 2LP on both sides, when comparing the same-size job (both SNFS and GNFS). I usually go for 5-10% more raw relations when stepping from...

I don't see a hard limit as a concept for any of the sievers- before the era of f-small, we showed that 15e can handle GNFS-198 and similar-sized SNFS. That doesn't mean it's a good idea, because...

Reserving 13_2_927m1.
I've decided to do some 16f sieving from Q=20-25M locally, so I may as well solve the matrix when ready.

First one done (quoted number for clarity), 1000@65e7 and 800@12e8.
Starting second one now.
Haven't finished building the new desktop yet, which is why this is taking 3x as long as I expected.

Not really; you'll have a slightly higher duplicate rate, meaning you may need an extra 1-3M raw relations to get the matrix size you expect. Sieve time will barely change.

Looks like a 6% better scoring poly than the last test, but only 4% lower sieve time.
Nearly a wash, but I=14 is also lower memory while being not-slower.
