Subject: [OMPI users] valgrind slaves in singleton mode
From: Brian Budge (brian.budge_at_[hidden])

Hi all -

I'm using openmpi to spawn child processes in singleton mode. If I use
mpirun, I can just run
> mpirun valgrind myprog

With spawn, it is expected that the spawned process will call
mpi_init(_thread). If I want to run valgrind on my processes, what steps
should be taken? I'm currently more interested in running valgrind on the
slave processes.

Thanks for suggestions.
