Info New version of Fahcore_22 with updated driver & CUDA requirements

[voodoo5_6k]

Just accidentally stumbled over CUDA errors in my FAH logs (was looking into them because my production was a little on the low side, WU's taking too long etc.).

There seems to be a new version of Fahcore_22 which is based on CUDA 11.x. This means, that the nVidia drivers & CUDA available in Debian 10 (excl. backports) are insufficient to run Fahcore_22 anymore... I definitely see this Fahcore_22 version in many, maybe even all current WUs. My system throws a CUDA error (CUDA_ERROR_INVALID_PTX), then falls back to OpenCl...

I'll need to move my system to a newer version in the next few days, as soon as I find the time to do that. Definitely before the folding race starts...

Fahcore_22 v0.0.18 updated driver and glibc requirements - Folding Forum

What needs updating? Linux ? Nvidia drivers ? Or just fah_22 ?

Basically, the NVidia drivers.

I haven't tested now, but it looks my computers will be OK:
Mint 20, Nvidia driver 470, CUDA 11.4, glibc 2.31

@voodoo5_6k , thanks for the heads up.

Thanks for the alert.

The FAH client automatically pulls the latest core, at least mine did. I was running the Nvidia 460 drivers and not seeing any errors, but updated to 470 drivers as they are now the (recommended) ones anyway. Everything continues to run smoothly. Just check your Nvidia drivers when you can.

Yup, thanks. Current estimate for discharge from the hospital is tomorrow, Monday ! S I should have time to check a few things before the race starts. Stats must be holding@20 m ppd for me based on the stats.

I'm back up running. I've moved the system to Debian 11 (currently nVidia driver 460.91 and CUDA 11.2) yesterday and it's running fine since then.

A quick look around on the net suggests to me that the CUDA 11 requirement can be met by having at least the Nvidia driver version 450.

460 works for me. 430 does NOT work. Most of mine were 430, and the oldest choice for upgrade was 460, and the one one that works most of the time without a linux reinstall.

Yeah, that seems to be about right. Debian 10 has 418 series driver what is too old in this case. So, that meant game over for my Buster install

For posterity: The public rollout of the respective OPENMM_22 core update was announced on November 14, just one day in advance of the rollout:
https://foldingforum.org/viewtopic.php?f=24&t=37545

This announcement also contains precise info about driver version requirements.

*Maybe* prior information about this update had been available to accepted members of the beta testing program, which takes place in a closed section of the foldingforum. It's a pity that there was still so much unnecessary guesswork left in the open section of the foldingforum, as well as in this very thread.
