How to clear GPU memory occupied by zombie process if it's parent is init?

Question

nvidia-smi screenshot

The process with PID 14420 is a zombie process and its parent id is 1(init). I want to clear 4436MiB memory occupied by this zombie process without rebooting.

How should I proceed?

You should find its parent and kill it. https://mcmap.net/q/25586/-how-to-kill-zombie-process has a good explanation. – Evangel

The parent is init, so I think there is no way of killing it without rebooting. – Faina

You could try to lower the initlevel to see if it does anything, but at this point, yeah, perhaps rebooting is the way. – Evangel

Answer 1

Use this command to list all the processes on the GPU (on Linux).

sudo fuser -v /dev/nvidia*

and find PID from the listed processes and simply use kill <PID> .

This will kill process with specified ID.
