"not a valid application" message from rocm-profiler #4

Open apanqasem opened 6 years ago

apanqasem commented 6 years ago

I am trying to profile HSA applications on a discrete GPU node.

Rocm 1.6; Radeon Compute Profiler (rcprof) 64 bits - V5.1.6400.

I copied the vector copy example in rocm/hsa. Built and ran the code. It ran fine. When I try the profiler, I get a "not a valid application" message.

(t1)%rocm-profiler -C ./vector_copy /home/apan/code/dlbench/opencl/vcopy/sample/./vector_copy is not a valid application

I am getting similar errors with other applications as well. Probably some flag I need to pass in the build process?

Can you try this with RCP 5.2?

Earlier versions of RCP check to see if the file being profiled is a valid ELF executable. This check was relaxed in RCP 5.2.

See https://github.com/GPUOpen-Tools/RCP/issues/2

The discussion there suggests that passing "-no-pie" while compiling allows profiling of applications that were previously giving "not a valid application" error

Thanks Chris. I don’t have root access on the machine. I will have 5.2 installed and update here.

The no-pie did not work for me.
