Sorry if this has been fixed for 1.3.4, but in the manpge for mpirun in
1.3.3 I noticed the following in the "MCA" section of the manpage:
Note: The -mca switch is simply a shortcut for setting
environment variables. The same
effect may be accomplished by setting corresponding
environment variables before running
mpirun. The form of the environment variables that Open MPI sets
are:
OMPI_<key>=<value>
However, as <key> is defined the env var one must set is actually
OMPI_MCA_<key>=<value>
