Using systemtap on MPI applications

[Olausson, Bjoern]

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
