Really? That doesn't sound right - we don't touch the
arguments to your application. We test that pretty regularly
and I have always seen the args come through.
Can you provide an example of where it isn't?
Sorry Ralph, I caused some confusion here. You are correct that
OMPI does nothing to muck with any arguments passed to the user
application -- they come through as expected.
I meant that when launching a binary with MPICH mpirun, it would
_append_ to the command line arguments things including
-p4pg and -p4wd, possibly -p4amslave, which we could detect at run-
time in the app context to determine that the app had indeed been
launched with mpirun.
Whew! Thanks for clarifying!
Brian
