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?

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"
