Could you please tell me what OMPI envars are broken? or what
OMPI envars should be there for OMPI to work properly?
Although I start my c-shell script from a bash command line(not
sure if this matters), I only add Open MPI executable and lib path to
$PATH and $LD_LIBRARY_PATH, no other OMPI environmental
variables are set on my system(in bash or csh) as I checked.
