Can not successfully use nsight compute on Jetson AGX Xavier

[1125111494]

Hello,
I could not find the nsight compute in the cuda folder, I could only find nvprof and nsys. So I have 2 questions:

1. How can I get nsight compute on Jetson AGX Xavier? From jetpack( but I did not see) or installed by myself? If I must install it, which version should I choose?
2. Can I use nv-nsight-cu-cli to locally profile a program on Jetson AGX Xavier, or I must remote profile from host? I have installed the latest nsight compute on the Xavier, but it did not successfully work. I have also tried to profile from host, but I get a similar error.

Hi,

Please install it on a desktop environment and apply the remote profiling.
Thanks.

Thank you for your reply!
I have installed nsight compute 2022.2 on my x86 linux host and I tried remote profiling, but I got the same error like this:

I’m using the root authority to profile.

Hi, have you profiled your app on Jetson AGX Xavier with nsight compute successfully?
I met some errors and I want to know how to confirm the version of nsight compute. My cuda is 10.2 and I tried to installed nsight compute (2019.5.0) according to the cuda version, however there is no version for Jetson.
Then I installed the version(2021.2.2) and I got the following errors:

==ERROR== Failed to prepare kernel for profiling
==ERROR== Failed to profile kernel “copyPackedKernel” in process 22220
==PROF== Received signal
==PROF== Trying to shutdown target application
==ERROR== An error occurred while trying to profile.
==WARNING== No kernels were profiled.

Hi, I haven’t successfully profiled, I have tried for days. Is the version of nsight compute important for a successful profiling? I installed the latest version directly.
By the way, I just noticed that the picture I uploaded was the result on Orin platform, but I got the same error on Jetson AGX Xavier platform.

Hi, did you installed the version of ArmServer? And if the latest version can use the GUI?

[1125111494]

I have tried installing armserver version on Xavier (but did not work), but AastaLLL Can not successfully use nsight compute on Jetson AGX Xavier - #3 by AastaLLL just said that remote profiling was needed. So I installed the x86 linux version on the host PC.

[jasonwu_www]

Did he mean we can only apply the remote profile and It’s not support for host profile on Jetson AGX Xavier?

[1125111494]

I think so… But my remote profiling also failed…

[jasonwu_www]

It’s so difficult… I have also tried 3 days. Can I have your Wechat ? Then we can talk about it.

(Xavier NX - Nsight Compute "Failing to prepare kernel for profiling" - #17 by AastaLLL)

From this solution, he recommended to reinstall the nsight compute.

It works! Thank you!!!

hhh, could you share me about how to deal with this problems? I want to profile the GPU utilization of my APP.

Hi,

Please noted that you will need to log in as root to get access to CUDA profiling.
Below is a comment about how to set up the root password for your reference:

No timeline for profiler Xavier: nvvp and nsight compute is not working in Jetson Xavier

Hi, Have you setup the root password first? The process should like this: 1.Setup root password $ sudo passwd root 2.Edit /etc/ssh/sshd_config diff --git a/sshd_config b/sshd_config index a32dc1d..d21cacd 100644 --- a/sshd_config +++ b/sshd_config @@ -30,6 +30,7 @@ #LoginGraceTime 2m #PermitRootLogin prohibit-password +PermitRootLogin yes #StrictModes yes #MaxAuthTries 6 #MaxSessions 10 @@ -54,7 +55,7 @@ # To disable tunneled clear text passwords, change to no here! #PasswordAut…

Thanks.

Hi, jasonwu_www, Sorry for getting back to you late.
I install cuda toolkit, nsight system and nsight graphics using sdk manager on a linux x86 machine.
Then I startup nsight compute from /usr/local/cuda-10.2/bin/nv-nsight-cu and use root ssh login and remote profile, you may refer to the response by AastaLLL just now.
