18201: no CUDA support anymore /SOLVED\

[NormalDiffusion]

Since yesterday I'm seeing problems with 18201 on most of my GPUs:
I'm getting following errors:
Windows 10:

Code: Select all

Error loading CUDA module: CUDA_ERROR_INVALID_PTX (218)

Ubuntu:

Code: Select all

Error loading CUDA module: CUDA_ERROR_UNSUPPORTED_PTX_VERSION (222)

This happens on:
- Titan XP (ubuntu, 2 different machines, as well as under Windows 10, so 3 different Titan XP)
- 1080Ti (ubuntu)
- 2080Ti (ubuntu)
- GTX 1660 Super (windows 10)

The only card that seems not to be impacted is a 2070Super (windows 10).

It also seems to no affect all 18201 WUs, as I just got 2 with functioning CUDA on the machine with the 1080Ti and the Titan XP (Ubuntu).
All systems have been rebooted to check, the CUDA problem stays.

There also seems to be a higher error rates inducing core restart on this WUs since yesterday (never had problem with them before!).

Thanks Jimbo, I missed this one!
I'll update the drivers and try to report later today.
Strange thing is that both Ubuntu machines have the same drivers installed, one is getting cuda, this other not...

If it is related to the 0.0.18 version, one PC may have a Work Unit that uses 0.0.18 and another PC's WU does not. The software won't download a new version until some WU requires it.

Ok, drivers updated, problem solved, performance increased.

Thanks Jimbo!
