Just move to 26e7 or 3e8; we're already 75%+ done with a t55.

I added 1400+ terms to 13^50. It may now be turned pink on the page, at 163 digits and a fully-ECMed C155.

ecm -v says 14,350.

I usually jump to B1=3e8 after 6000, doing the second half of a t55 there. I'll stay at 15e7 this time instead.

I suggest starting at T60 at yoyo; we can get through T55 pretty quickly.

I'll contribute 2000@15e7 to get that started.

My sieve/host resources are booked the next two months.

Sorry I forgot to build a params file for Ryan- I think I have time for that shortly, seeing as how I have two days left in covid isolation.

A guess is that P95 is using AVX-512 so the CPU slows itself, but GMP-ECM isn't waiting on memory so is using the CPU more heavily.
I thought AVX-512 would step down no more than 200Mhz, so my guess...

No, a C102 can easily be solved by QS. It's not the ideal method, but shouldn't be more than 2-3x slower than GNFS.

No, I think your way is actually more accurate, since it measures when a matrix can be built of a certain density rather than using user-set guesses for number of relations to find.

You're wasting your time & electricity. mprime is the wrong tool for the task, and your curves aren't going to find a factor.
Run GMP-ECM, or wait for an upcoming P95/mprime with enhanced ECM.

I hope you mean you set B1 to 7.6e9 and let B2 be whatever GMP-ECM chooses. If you've set B2 = B1, that means you're not running stage 2 at all and that's not a good plan (to put it mildly).
