1) Message boards : Problems and Help : geneferocl crashes on Fedora 31 with RTX 2070 and 440.59 drivers (Message 137981)
Posted 39 days ago by Profile geeknikProject donor
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.

Posted 1483 days ago by Profile geeknikProject donor
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.

My team was #58, I was #209. Not bad. I think I had 10 cores, 18 threads going on SGS 24/7 for the challenge. =) Time to switch everything back to PRPNet.
