NvPerf Samples NVPW_InitalizeHost failed

Developer Tools Nsight Perf SDK
1

I just downloaded the Perf SDK and compiled the examples, but they don’t work, even when run as root and with profiling enabled for all users using a conf file with ‘NVreg_RestrictProfilingToAdminUsers=0’ in modprobe.d and rebuilding initrd. Did I miss any requirements, dependencies or is there some installation required? I’m on Ubuntu 22.04 with an RTX3080 and driver version 510.85.02.

Hi wdv50jkc,
Have you set the LD_LIBRARY_PATH environment variable before running ./triangle?
This is required according to the user guide:

Thanks, I’m stupid :D
But the user guide seemed unavailable when I tried downloading it a few days ago… Now it is available, so I guess that wasn’t entirely my fault xD

Glad to hear it works. :)
