Frame time increases from 75 seconds to 90+ minutes for 16722 WU, after restart due to bad allocation.

[ETA_2025]

My GPU is doing Project: 16722 (Run 262, Clone 2, Gen 458), which will take more than six days to complete. The Timeout is three days.

It completed 83%, before the bad allocation occurred. Since it restarted, it's taking more than 90 minutes per frame, up from 75 seconds before it restarted!

Rebooting the computer caused the WU to restart, this time with the 75 second frame time.

Can someone explain what happened?

[Joe_H]

I suspect you had a video driver crash that caused the bad allocation error, and the video system reinitialized. Apparently it also corrupted the checkpoint so the WU started over from the beginning. However the reinitialization of the drivers went, the client and folding core could not detect CUDA being available and started up in OpenCL mode:

Others in the past have reported sometimes having their GPU stuck in a slow clock mode as well after a driver reinitialization due to a crash, I suspect that also happened here and caused the very slow processing until you rebooted.

After a GPU/driver crash, the GPU often stays in low power mode until you reboot the system ...

Thanks Joe_H and toTOW. It's good to know what to do if it happens again, though I don't know why the GPU/video driver crashed.
