/opt/nvidia/nsightsystems/nsightsystems-2019.3.4/Host-x86_64/nsight-sys

Does this support profiling localhost on host system?

I tried connecting to 127.0.0.1. It seems to connect after entering the correct password, but there’s a Communication error immediately afterwards.

Looking at More info shows this:

NotFoundError (127) {

Hi @sleff,

x86_64 isn’t listed in “Supported Platforms” section in System Requirements.
Please try with other version. Thanks.

@VickNV so you are saying that this version of Nsight Systems does not support x86_64, even though the path to the executable contains x86_64, is that really true?:

/opt/nvidia/nsightsystems/nsightsystems-2019.3.4/Host-x86_64/nsight-sys

There is another nsight executable under this path:

/usr/local/cuda/NsightSystems-2019.2/Host-x86_64/nsight-sys

This one has the option of a direct Localhost connection in addition to SSH.

However, when I configure it to profile target application /usr/local/driveworks-2.2/bin/sample_autodrivingbeam, it does not start the application.

pid_xxxxx_stdout.log:

WindowGLFW: Failed initialize GLFW

pid_xxxxx_stderr.log:

ERROR: ld.so: object '"/opt/nvidia/nsight_systems/libToolsInjection64.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

It is used for remote profiling.

Please make sure you can directly run the application without the error first.

Application runs directly with no error

This error looks not related to nsight-sys but window initialization error.

Solution:

Use this executable instead:

/usr/local/cuda/NsightSystems-2019.2/Host-x86_64/nsight-sys

To fix GLFW error, make sure DISPLAY environment variable is set correctly.
