Anthony --
I'm really sorry; we just noticed this message today -- it got lost
in the post-SC recovery/holiday craziness. :-(
Your request is fairly reasonable, but I wouldn't want to make it the
default behavior. Specifically, I can envision some scenarios where
it might be problematic (e.g., heterogeneous situations -- which we
don't yet support, but definitely will someday).
How about this -- an ISV asked me for a similar feature a little
while ago: if mpirun is invoked with an absolute pathname, then use
that base directory (minus the difference from $bindir) as an option
to an implicit --prefix.
(your suggestion may actually be parsed as exactly that, but I wasn't
entirely sure)

This is not a bug just wonder if this can be improved. I have been
running openmpi linked program with command
<openmpi-install-dir>/bin/mpirun --prefix <openmpi-install-dir> \
--host A -np N a.out
My understanding is that --prefix allows extra search path in
addition to
PATH and LD_LIBRARY_PATH, correct me if I am wrong. Assuming that
openmpi's install directory structure is fixed, would it possible for
mpirun to search <openmpi-install-dir> automatically for libmpi.so &
friends so to avoid the redundant --prefix <openmpi-install-dir> to
mpirun ?
Thanks,
