LaunchFailed Error in Nsight Compute with CUDA Kernel Analysis

Developer Tools Nsight Compute
,

Hello,

I’m encountering an issue while using Nsight Compute to analyze a CUDA kernel. Here are the details:

  • Error Message:
  ==ERROR== LaunchFailed
  ==PROF== Trying to shutdown target application
  ==ERROR== The application returned an error code (9).
  ==WARNING== Failed to import the following source files:
  ==WARNING==  default
  • Nsight Compute Version: 2024.2.1.0 (build 34372528) (public-release)
  • NVIDIA Driver Version: 520.61.05
  • CUDA Version: 11.8

I’ve checked my setup and everything seems to be in order. Could anyone provide insights or suggest steps to resolve this issue?

Thank you!

ncu 2024.2.1 is from CUDA 12.5 Update 1. I don’t think it’s compatible with CUDA version 11.8. Can you try the ncu from 11.8, or use a newer CUDA toolkit and driver from 12.x for your application?

I updated ncu to 2022.3.0.0 and profiled the app again. However, another error occurred:
