I have two questions about mpb-mpi.
1. If I run:
mpirun -np 2 /usr/local/bin/mpb-mpi foo.ctl > foo.out
There will be an error:
linmin: WARNING: ROUNDING ERRORS PREVENT PROGRESS
0 - MPI_ALLREDUCE : Message truncated
[0] Aborting program !
Does the oridinary serial version of MPB work on your problem? If not,
there may be a problem with your MPB installation (try configuring with
--enable-debug and see if the problem recurs) or something weird about
your input file.
2. To run mpb-mpi, I have to include the path /usr/local/bin/ before mpb-mpi
very time, otherwise it cannot find the program. Is there any way to avoid
this, or something wrong with the installation?
/usr/local/bin should be in your $PATH variable (echo $PATH to see). If
not, you should add it:
setenv PATH /usr/local/bin:$PATH
If /usr/local/bin is in your $PATH, then there may be something wrong with
your MPI installation.

PS. When reporting problems, it's a good idea to say what operating
system you are using, what compiler version, and what MPI version.
