Hello SystemTap users,
I am curious if there is a smart way to trace (basically IO) for MPI
applications running on multiple nodes?
I guess it would be possible to either run stap globally or run
"mpirun <options> stap script.stp -c mpi-application"
Is there any "good practice" to profile MPI-applications with
SystemTap if at all possible?
Kind regards,
Bjoern
