Hi there,

We often run F@H on systems that need simulated load or what have you – makes productive use of equipment that's being tested for another reason. I'm seeing this on one such system, however, and am not sure what to make of it. Any ideas? These are RTX 2080 Ti cards, and they've got driver 470.74. F@H client is 7.6.21, and I know this both did, work, and I've seen the occasional work unit succeed in the last couple of days I've been running (CPU WUs are running fine):

I don't really see any more information anywhere. Just FWIW, the reason I'm running this on this machine is that I suspect a problem with one of the GPUs (falling off the bus), but there's no indication that that is causing this problem.

If you try to start the core manually from a terminal, you'll get a more detailed error.

See the global announcement about core 22 v0.0.18 : viewtopic.php?f=24&t=37391

Thanks. My guess is I'll need to build a new container with a newer version of the OS with newer GLIBC support. I may have used CentOS 7.x for my current container.

I confirm that CentOS 7 has a too old version of glibc ...

CentOS 7 (and RHEL 7) doesn't even have Python 3 in the default repo... RH releases are more conservative than carrot-haired 70-yo presidents.

... since FaH currently doesn't need Python 3 they are a perfect match

No, because CentOS 7 has a glibc implementation that is too old for core 22 v0.0.18 ...

Generating a new Singularity container (that's how I currently run FaH on our clusters) that uses CentOS 8 solved the problem with no other changes.

It seems kind of like a shame, but I guess it's true that most of the target audience for this software isn't running legacy-ish enterprise systems (and we have a solution for that anyway).
