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?

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 migrate-n

This will not work because it uses a "single_master-many_worker"
architecture and needs at least TWO nodes Peter
