Found the problem. There was a Mesa-libOpenCL installed on the system that was no longer necessary and the GFN app was trying to select a non-existent Mesa OpenCL device instead of the Nvidia OpenCL device. Thank you for the information about the "clinfo" tool, I was not aware it existed.

Unable to participate in the GFN project with my Fedora 31 box due to a crash.

How long will http://uwin.mine.nu/PRPNet/ be down? I have a new 24 core server I'd like to start hunting primes on. http://isup.me/uwin.mine.nu says its not just me. (:

7) Message boards : Problems and Help : prpclient kills itself, unable to determine why (Message 92852)
Posted 2581 days ago by geeknik

So I'm running the prpclient and it runs fine up until it tries to work on a Wieferich work unit and then it kills itself as seen here. I'd love to know how to fix this. Considering it's running on a headless machine in the corner with nobody connected to it (and no keyboard), it is impossible that someone did a ^C on it. Thanks.

I just ran this on my Dell T3500 (quad core Xeon workstation) that has a ATI FirePro V4800 (FireGL) w/ 1GB RAM, and it seems to run fine. Makes the desktop a little laggy, but otherwise, no problem.
