Hi everyone,
I’m currently interested in profiling an application that exercises the DO CONCURRENT base language support for Fortran, as well as some OpenMP and OpenACC. I would like to be able to view the PTX source code in Nsight Compute, like I can when using nvcc and looking at C code. This is currently the command I’m using:
nvfortran -O3 -march=native -acc=gpu -mp=gpu -stdpar=gpu -gpu=ccnative,managed,unified,keep,lineinfo,ptxinfo,debug -Minfo=accel ../advection.f90 -g -Xptxas=-v -Mdwarf3
Howeover, after running ncu and collecting a report to copy over to Nsight Compute, the only source views available to me are the original Fortran, and SASS. I do not get an option for viewing PTX, despite producing a .ptx file with the keep option. Is it not possible to get that PTX view with nvfortran? Clarification, I’m not trying to debug or step through PTX code, I’m just trying to associate the collected ncu statistics with the PTX so I can see which instructions are causing which events.
Thanks in advance,
Ivan
