Project 13414 2 Faulty WUs

Postby pylgrym » Mon Jun 22, 2020 7:08 am

I've had 9 WUs on project 13414 in the last 2 or 3 days, 2 in the last 24 hours were faulty. Here are the relevant logs:

Re: Project 13414 2 Faulty WUs

Projects 13414 are experimental and tend to have more errors than most other projects. They are being monitored closely and the PI learns from each error report ... generally leading to a better analysis for future WUs.

Then, too, FAH tends to be a more stringent overclocking benchmark than the traditionally used versions. Your nan errors might just be because you're overclocking and provoking an instability. Try removing the overclocking if you have one set and see if it helps.

Thanks. I'm not overclocking (or underclocking). I've since had another 8 WUs from this project with no apparent problems aside from some rather erratic points allocations. No big deal and good to know it's being monitored.

closely monitored.

The methodology is brand new and is very challenging.
