1) Message boards : Generalized Fermat Prime Search : Genefer-19 tasks invalid (Message 151561)
Posted 22 hours ago by Jim WilkinsProject donor
Well, that's annoying! I very much appreciate the diagnosis. Guess I should go figure out how to diagnose a GPU problem. Since I have never seen this on my CPUs, I have to agree. This has happened twice on GFN-19 also. I wonder if the failure rate is proportional to the size of the GFN.

I have another "invalid", this time on GFN16. This is the STDERR data:

This particular iMac does not have Nvidia H/W, at least I don't think it does.

What is it telling me?

All,

All of a sudden I am getting invalid results in Genefer-19. This is after many valid results. How do I research this?

Agree...I use two iMacs at home, that's it. I do this because its fun, I enjoy badges I may find a prime.

So I checked my preferences. For my CPU I have limit of one thread at 50% CPU, and Max # of simultaneous PrimeGrid tasks set to unlimited, and Multi-threading: Max # of threads for each task set to 1. For my gen17 preferences I have checked CPU and AMD/ATI GPU (OpenCL).

I have 6 CPU tasks running and many GPU task running. However, my results show its nothing but CPU tasks running.

What's happening?

It Appears that all of my openclatiGFN17LOW tasks are being reported as cpuGFN17LOW tasks. Anyone know why?

Not that I am complaining. I get more of these than any other tasks. I wonder why.
