I am trying to evaluate a heavy kernel that runs on CUDA GPU.
I work on JETSON NANO device.
Usually I got running time of 11milli, but sometimes I get 20milli and sometimes even 3milii.
I thought that maybe the display card also uses the GPU and that’s why I get different timing, so I tried to disconnect the HDMI cable, and power-up without it, but it didn’t help.
So I thought that maybe other LINUX processes also uses the GPU.
Is there a way to set the compute mode in JESON NANO to exclusive, such that only my process can use the GPU ?
My application is real-time and needs to work deterministically.
I read that the nvidia-smi utility doesn’t work on JETSON NANO.
