Yes, ECMF is affected. I'd give 30.9 try if you can live with its shortcomings (mainly no save files in stage 2).

30.9 build 2

If you aren't doing ECM, do not download! PRE-BETA software!

What's new over build 1? Should be a little more stable and a little faster. Fixed nasty bug that sometimes caused...

Like P-1, prime95 ECM will choose B2 automatically. To simplify matters I'd just start with B1 = 1000000. Depending the B2 chosen by prime95 will determine the number of curves that need to be...

Thanks for the great data! From that I see that the "prime95 guessed optimal B2/B1" is not terribly bad. We need to wait for a prime95 that is fully optimized in stage 2. Then gather similar data...

Best from this table is: 1.5e13
11285 × ( 950 + 293.4 ) = 14,031,769

This is not best configuration for this computer though. The fact that only one core is used during stage 1 is a big...

Just hidden. SUMOUT checks only available in SSE2 FFTs (old computer?). SUMOUT checks were the first error checks prime95 used. They are "fuzzy". Two floating point check values are supposed to...

Can you post a table containing B1, B2, runtime, t5 curves needed?
Example: 110M, 105*B1, 950+5.3, 42000
I'm surprised at your preliminary results. Sounds like prime95's optimal B2 guess needs...

If you use B2=100*B1, prime95 should select a close-to-optimal B2 (if there aren't any bugs)

The best B2 value is determined by shortest time to complete the "t" level you are working on.
Say,...

ECM users - version 30.9 (see post#64)

I've been very slow at writing new code lately -- summertime I guess.

Is there interest in a pre-beta version of 30.9 that uses a GMP-ECM-like stage 2? It's been working and pretty stagnant for...
