I ran some benchmarks on Cat 13.8 beta.



Similar/slightly improved vis-a-vis 13.4.

One thing that might have improved is consistency in run times. The run-time/credit ratio is qualitatively more consistent (but that might be a coincidence of the wu's getting sent right now).

Here is a chart of the elapsed vs credit for the MB GPU wu's on my acct page right now:



The points outside the two angle-range clusters are 30-spikes and -9 overflows.

Better consistency might explain why the APR on my account page is finally starting to calculate a value for MB v7. My understanding is that if the observed run times vary too much the APR algorithm declines to calculate a value.

No, I reported to the boinc_dev list last night that the AMD APR problem was still there, and Eric has diagnosed, and Fixed it:

Thanks for staying with that issue Claggy.

Doesn't help the hosts's like Guy's that have a too High APR already, so all tasks end in Maximum Time Exceeded, he'd have to run Fred's reschedule program and use it to protect against -177 errors, and hope what it does is enough:

Happy that APR is finally working. On the down side, now I get to see what a wretched number it is for V7...in the low 30's. Eeeesh that looks like a CPU value.
