[ptp-dev] Prepending MPI Launch Command

[Wyatt Spear <wspear@xxxxxxxxxxxxxx>]

Greetings,

There are a few parallel performance tools which need to be composed with the mpirun (or equivalent) command.  On the command line this might look like:

performance_tool mpirun -np 4 mpi_app

Is there any way that this could be supported with the PTP launch system?  I am not really familiar with the resource manager API but I am guessing that this would have to be done for each resource manager implementation.  I'll start looking through the code myself pretty soon but if anyone could point me in the right direction I would really appreciate it.  Similarly, if this is a non-starter for some reason it'd be good to know before I start.

Thanks,

Wyatt Spear
