Offload the CPU as much as possible
Hi,
I have Immich v1.123.0 running with a Nvidia Tesla T4. I want to offload the CPU as much as possible, so i have the
hwaccel.ml.yml and the hwaccel.transcoding.yml enabled in my docker-compose.yml. In what way, or what jobs, are offloaded from the CPU with this enabled, or how can i check this? The CPU still spikes to 99%-100% from time to time.
This is not a huge issue ofc, but i want to keep the CPU load as low as possible ofc.11 Replies

If this ticket can be closed you can use the /close command, and re-open it later if needed.I understand that most of the things above are needed if something is not working or broken. I just have a informative question.
Using hardware acceleration doesn't mean the CPU won't do anything. hwaccel is fast enough that the CPU is plenty busy just giving the GPU work to do

Thats not what im saying. Or expecting, im asking how i can check that its actually using the GPU instead of the CPU? Sorry if my question wasnt clear enough. I have edited the post.
by monitoring your GPU with nvtop for instance
Or checking the container logs, if it tries to use the GPU and fails it should show up there
[root@immich docker-data]# docker exec -it 0641f661c6a7 bash
root@0641f661c6a7:/usr/src/app# nvtop
bash: nvtop: command not foundnvtop is not inside the container
Outside the container only
nvidia-smiworks. nvtop is not known... well you need to install it first
Alright, ill start some jobs to see if it does something
I guess its working like it should..
I think i expected more load on the GPU and waaay less load on the CPU. Ill see how it all preforms now
Just consider that it might be doing 10x the load
The CPU is busy supplying the GPU with tasks
the GPU zooms through the tasks
CPU still at 80% but overall it takes 10x less time
