I suspect that the problem is not that LSF does not copy the
environment over but that Open MPI is accessing the other nodes not
using LSF's method. Below is a related message by you that I have
not tried to figure out yet, I was hoping for pointers by those
people that use LSF:

If this turns out to be all that is needed then is it possible for
OpenMPI to autodetect when it is running under LSF and then use
lsgrun instead of rsh/ssh?
