Nsight Compute for Jetson Orin


Is Nsight compute available natively on Orin? I could not find it. I can find Nsight Graphics and Nsight Systems, but not Nsight compute.
According to this, Jetson Developer Tools | NVIDIA Developer nsight compute is included in the cuda tool kit, but I cannot find it inside Orin’s cuda bin (/usr/local/cuda-11.4/bin).
Also here, explicitly says “running directly on Orin”

Can anyone tell me where to find Nsight Compute? Or just like before I had to use a host Ubuntu to do remote profiling?


You can find the package in the below link directly:



Thank you so much.

Accroding to the repo, looks like nsight-compute is only available on amd64. So I guess that means a host machine is required.


We can find the ncu binary on the Orin.
Please give it a check.

This is weird. My /opt/nivida/ has nsight system and nsight graphics but not nsight compute.

Anyway, I found a workaround. During a remote profiling, the host machine deploy nsight compute binaries under /tmp/var/ (at least for me). After that, the folder is not deleted. The binary is /tmp/var/target/linux-v4l_l4t-t210-a64/ncu. So I just copied the entire folder to somewhere else and now I can profile locally.

Thank you.
