Aha, so something accelerator-y where they do general purpose computation.

So what's the big picture here: they count all the errors and when they
reach a certain amount, they decide to replace the GPUs just in case?

Or wait until they become uncorrectable? But then it doesn't matter
because we will handle it properly by excluding the VRAM range from
further use.

Or do they wanna see *when* they had the correctable errors so that they
can restart the computation, just in case.

Dunno, it would be a lot helpful if we had some RAS strategy for those
