CUDA_MPS_ACTIVE_THREAD_PERCENTAGE not effective on Jetson

I’m using Jetson orin nano, and trying to use MPS.
My goal is to run 2 heavy apps (where the GPU is in full utilization), while limiting the first one (app_0) to access only10 % of resources by using CUDA_MPS_ACTIVE_THREAD_PERCENTAGE.
Running the following lines and I see that CUDA_MPS_ACTIVE_THREAD_PERCENTAGE doesn’t affect the performance at all (I’m checking both the run-time duration and the prop.multiProcessorCount).

My question is, does Jetson ORIN NANO supports CUDA_MPS_ACTIVE_THREAD_PERCENTAGE ?

The commands I ran are:
export CUDA_MPS_PIPE_DIRECTORY=/tmp/nvidia-mps
export CUDA_MPS_LOG_DIRECTORY=/tmp/nvidia-log
nvidia-cuda-mps-control -d
export CUDA_MPS_ACTIVE_THREAD_PERCENTAGE=10
./app_0 &
export CUDA_MPS_ACTIVE_THREAD_PERCENTAGE=90
./app_1 &

Thanks!

Hi,

There are some limits and rules to setting the value.
Please check the document below for more information:

Thanks.
