Subject: Re: [MTT devel] mpi_details section with different scenarios for command line params

What exactly do you want to do?

For example, Cisco's MTT files simply list a huge number of different
mpirun command lines in the MPI Details section (25, in one case,
IIRC). So I run lots of different cases for each MPI test (e.g., with
leave pinned, without leave pinned, ...etc.).
