Not a bug, just a heads up because this wildly messes with the VIRT column. (Everything is red, and the number of significant digits goes waaay down.) On my computer this region is reliably located here:

GPU Carveout (reserved       1000000000-7000000000       [384.0G     0K     0K     0K] ---/--- SM=NUL          ... address space (unallocated)

Maybe this might be worth adding special accounting for?

The displaying of memory related numbers got overhauled with 40441dc.

@saagarjha is this still an issue?

Hmm, it's still not quite how I would have liked: now everything that doesn't use the GPU gets rounded down to zero. Would it be possible to keep a decent number of significant figures for all processes?
