This may not be very helpful overall. Other people factoring small numbers won't know which numbers have been ECMed, so will have to run ECM against every number before they switch to QS/SNFS/GNFS. Which wastes effort if it has already been ECMed.
It would be more helpful to concentrate on factoring the 1000 lowest numbers that yafu@home skips over. (It would be even more helpful if they didn't skip them.) Or generate Primo certificates for the smaller PRPs. Just my opinions. Chris (using SNFS to split the easier numbers in the first 10,000)

with 20 curves @ B1=100r3, I *check* about 2530 65108 digits numbers by minute. That's about 2 seconds of work by numbers. Even if one wanted to factorise every number, 2 second is a really small amount of time compared to a ecmtest &gnfs factorisation of a 105110 digit number, right?

yafu@home, as well as "Other people factoring small numbers" have to do ecm anyway. Just switched off all my helpers that fully factored "small numbers" for a very long time, now focusing on aliquotS <115digits in size. Last fiddled with by RobertS on 20120816 at 22:10

During this minute, I get around 13% of factored composite. Meaning around 3 or 4 composite factored by minute.
I don't spend much time on each composite, but I use a sledgehammer. If it break, it's good, if not, too bad. I hit the next composite, in the hope it break quickly. pratical case : 8635 composite tested ,1070 factored best scenario : 30 tested by min, 288 minutes , 4H and 48 minutes worst scenario: 25 tested by min, 346 minutes, 5H 45 minutes. If I tweak the test a bit more, I 'll get more factored . But the goal here is to hit fast, not accuratelly, nor persistently.

This looks like people have gone crazy running curves. My intention with writing this script was to run a tiny bit of ecm on each number such that there isn't much work duplicated if someone runs a full ecm on this number. Some people here seem to be running a large part of t30.
I personally like the fact that by doing curves at 25 digit level I can occassionally find 3035 digit factors. It might be worth running a worker with P1 for a while.

If anyone is spending a lot of time doing this then it is probably better to pick composites at random and factor them completely.
