nice joke! :o)

This is known and not an option for us. There are too much variables in
the interactive environment which should not be forwarded...
What I asked for is something which could replace
mpiexec -x FOO -x BAR -x FOBA -x BAFO -x RR -x ZZ ..
(which is quite tedious to type and error-prone for the users) by
setting some dreamlike value, e.g.
export OMPI_PROVIDE_THIS_VARIABLES="FOO BAR FOBA BAFO RR ZZ"
At least some envvar, whose content would be simply added to the comand
line, could help:
export OMPI_ADD_2_COMMLINE="-x FOO -x BAR -x FOBA -x BAFO -x RR -x ZZ"
Well, this are my user's dreams; but maybe this give an inspiration for
Open MPI programmers. As said, the situation when a [long] list of
envvars is to be provided is quite common, and typing everything on the
command line is tedious and error-prone.
