visual profiler with MPI

Accelerated Computing CUDA CUDA Programming and Performance

I’m trying profile a MPI multiple-GPU program.

I’m not sure if the profiler works with MPI. If so, anyone knows how to specify arguments in visual profilers’ session settings?

If I run it without profiler, I use following command line:
mpirun -np 13 -machinefile mfile my_execution_file_name

Thanks a lot,

Yao

In the session settings you can just fill in the needed command line.

Hi, thanks for reply. But this doesn’t work for me.
