Yes with hydropower's exe it's good settings, but with default genefer on primegrid, it's not good.

what is the correct command line to run then?

Posted 3409 days ago by Profile HA-SOFT, s.r.o.Project donor


so does that mean the titan is 40% faster or am I misreading it somehow?



This is expected situation because GTX6xx are not strong in double precision.

With shift=8 I have managed genefer to work stable (I hope).

Now the running task is about 38%. Expected total time looks very similar to my 580.

-b3 looks buggy



That's with the new executable, right?

If so, that's good news as it means it solves at least some of the problems with the WR tasks.


Yes new executable.

If that's with the double precision boost enabled, this is certainly disappointing. Those numbers don't look that much better than a 580.


Yes
