In line 568 of openmpi-1.2.2/orte/mca/pls/rsh/pls_rsh_module.c
the call "p = getpwuid(getuid());" returns an invalid shell on our

local
shell is not defined and only the user's ~/.profile gets exectuted
in lines

having
OpenMPI do this for them in lines 981ff.
Wow -- neat! We certainly didn't think of this case. :-)
Before LSF starts a user job, it sets their complete environment
including
the SHELL environment variable. I am wondering whether OpenMPI
could look
at that env. variable in lines 567ff in addition to or instead of the
getpwuid() call.
A good idea; yes, we can do this. I'm sorry that it won't make the
1.2.3 release, though. I'll file a ticket.
FWIW: we're actively working on native LSF support in Open MPI such
that this kind of rsh tomfoolery won't be necessary in the future.
We hope to have it ready for the 1.3 series.
