Thanks for doing the tests, bsquared.

Anyone still have any poly selection going on?

I am going to run another overnight search.

As long as we are using Jason's msieve-gpu branch, and there is not yet a gpu version of lasieve4, then I think it does not take away from optimality to do a bit more poly searching than usual.

I have not found anything better, and I'm quitting the search.

Now on a C151.

I've started a run of 1000 curves @ B1=43000000, B2=388112953420. ETA 15 hours.

bsquared · 2009-11-11, 18:00

400 curves at B1=1M done.
Starting 2k curves at B1=3M (ETA 4hrs).

How does one report work to the DB now? There used to be a 'report work' button that I can't find anymore.

go into the sequence,and beside the quick ecm button there is a >> button,click it,and at the bottom of the page you cant report the curves you've done.

Looks like you have to be logged in, as well. Thanks.

After 2200 curves @ 11e6 I found a nice p47
