    there's definitely a correlation between certain freq and DF ranges to run time, you see some tasks running 7-8mins, and others running like 4 mins (nvidia RTX cards). I haven't looked hard enough to see exactly which freq/DF combos run fast and slow, but a spot check did see runtime differences that matched up with freq/DF.

     

    and CPU def seems to be a major bottleneck, I see only barely slower runtimes on a 2070 vs a 2080ti on an identically spec'd system. without the CPU bottleneck, the 2080ti should be close to 2x as fast.

        I actually don't even SEE an S3 validator created yet in the server tables.

        Just the old S2 validator.

              It probably just means that the validator needs tweaking for the conditions of the new S3 tasks series.  My guess is that adjustments will probably be made and the tasks then be resubmitted for validation - or something like that.

              Teething problems like this have happened before.

              As I mentioned earlier on, this transition seems quite unusual and quite rushed, so it's probably not a great surprise if there are some issues.  I'm sure it will all get fixed in the end :-).

                Thanks for your response, Gary.

                It seems to have happend only yesterday, 27th, with 28 such tasks concerned.

                Seems to be OK now.

                Thought I'd mention it.

                We are having troublesome times !

                  Looks like my Gravity Wave uploads are hanging.

                  Got more than 40 waiting.  And have basic backoff's running.
