Message boards : Graphics cards (GPUs) : Work units failing in 64-bit Linux

Work units are failing on 64-bit linux. This is a research unit that has proven itself to be very stable, but is idle at the moment. Thought I'd try to take advantage of the idle time.

Do you always fail or just sometime? | |

The first eight work units failed, so I suspended it at that point. It's definitely not overheating. It's housed in 1u rack unit in a frigid, air conditioned room. I wonder whether it has something to do with | |

Found the problem. The Einstein@Home beta app was the culprit. I had left something around that GPUGrid didn't like. Unloading and reloading the kernel module fixed the problem. | |
