Hello Jeff,
the problem is solved, I installed openmpi-1.1a1r9045, and now it
works.
Thanks,
Andy

Ok, we've finally migrated over all the I/O forwarding fixes to
the v1.0 branch. They've been on the trunk for a little while, but
we have certain procedures that have to be followed to get things
committed on the release branch and it took a little time -- sorry
about that. Can you try a nightly tarball from tonight -- either
the trunk or a v1.0 tarball and let us know how it goes? On Feb

Hi Peter, I tried first with 2 nodes, but is was the same
problem, it hang. Then I tried with 1 node, and copied that
output in my previous mail. When I checked the process status
(with 2 nodes), one of the migrate processes was using 100 %, the
other was sleeping. But after 15 minutes, still no output change.

Dear Andy, you wrote that with openmpi:
avierstr@muscorum:~> mpiexec --hostfile hostfile -np 1 migrate-n
it does not work, but with lam-mpi
avierstr@muscorum:~/thomas> mpiexec -np 2 migrate-n
you started openmpi on only _one_ node, migrate needs at least
_two_ nodes to run (as you did in lam-mpi) migrate actually
aborts when running on only one node, it should show an error
message so, like this zork>which mpirun /usr/local/openmpi/bin/
mpirun zork>mpirun -machinefile ~/onehost -np 1 migrate-n

In file main.c on line 697 This program was compiled to use a
parallel computer and you tried to run it on only a single node.
This will not work because it uses a "single_master-many_worker"
architecture and needs at least TWO nodes Peter
