Profiler can't display SASS source instructions

After switching to CUDA Toolkit version 10.0.130, the source profiler shows my source correctly, but the SASS source shows as “???”.

Here’s a screenshot


  • CUDA Toolkit: 10.0.130
  • Nsight: 6.0 (
  • Windows: 10
  • Visual Studio: 15.8.4


  • This worked fine with 9.2
  • Visual Profiler (standalone) works OK
  • The problem happens with "samples" (matrixMul) also.

Thanks for the feedback. We are looking into this issue and will reply with more info soon. DTCOMP-1411
