[/CODE][/QUOTE]Two in a row!

:bow: :bow:

A few more than two, actually, -- the iteration is 5185 now (size 183).

Batalov, do you need help running the seq or do you prefer working alone?

I guess I should tell my machines to stop working on that c170...:smile:

I only had these many curves done:

60@2e3 296@11e3 963@5e4 1620@25e4 2560@1e6
4800@3e6 4520@11e6 7120@43e6 372@11e7
[/code]Moving to whatever's next... unless Batalov does wish to run with it a while...

c147 is almost done.

Batalov, what hardware are you running that ECM on? Just curious for curve execution time comparison. Thanks!

Some pretty standard (maybe even a bit old) 2800-3000MHz Intel CPUs.

Strange. Mine is much slower on a Core i7 processor, even with a 64-bit compilation. Are you on linux?

The c158 is ready for GNFS. (The sequence is released.)
