ECM numbers

[yoyo]

Hello,
I'm pretty new to GIMPS.
Is there somewhere a list of numbers which I can run with gmp-ecm?

Just to clarify: This is a list of numbers to run GMP-ECM on, but is not related to GIMPS. The only GIMPS ECM is on (relatively small, where they're in the 25-35 digit ECM range) Mersenne numbers and Fermat numbers, and is best run through Prime95, not GMP-ECM. (Prime95 is better geared for ECM on such large numbers, with status updates throughout, checkpoints, etc.)

Let's assume I will run the last one in the list (4^419-3^419) with gmp-ecm, but not with ecmnet client. How do I know which amount of curves and B1 were alredy done and which ones are needed?
And how do I report the amount of curves which I run?

When I get back home and back to what passes for normality, I'll ask the ECMnet server what it thinks has been done on that number.

The easiest way of reporting the number of curves done is to mail me and I'll update the ECMnet server with your work.

All numbers with SNFS difficulty >250 have passed t40 (some of them - t45) on my ECMNET server.

I believe Paul's server will show that the 40-digit level (B1 = 3e6) has been completed and that something like 4854 curves still remain to be done at the 45-digit level (B1 = 11e6). Of course, the server appears to be configured to do a total of 5500 curves with B1 = 11e6, which is contrary to the recommended number (see http://www.loria.fr/~zimmerma/records/ecm/params.html), so you may want to run somewhat fewer than the server is actually suggesting. Or not. Whatever.

Also, P-1 and P+1 have already been run with B1 = 11e7.
