I'm using openmpi-1.4.2. I need to run pvserver(a mpi program of paraview) in a cluster. I have Mac OS X 10.6.4 in all my hosts and in the server. I had configure ssh

with no password.

$ mpirun --hostfile myHostFile -np 12 pvserver -tdx=4 -tdy=3
Listen on port: 11111

Waiting for client...

Then in my client i run paraview an I connect to the server
$ paraview
Waiting for server...


The server tries to open the viewport in the other computers but here is the error


$mpirun --hostfile myHostFile -np 12 pvserver -tdx=4 -tdy=3
Listen on port: 11111
Waiting for client...
Client connected.

I read about that error. I found this thread http://www.mail-archive.com/paraview@paraview.org/msg06964.html


Here Takuya OSHIMA wrote that we need to run openmpi like this:

$ mpirun --no-daemonize --hostfile myHostFile -np 12 pvserver -tdx=4 -tdy=3


But this flag --no-daemonize is not part of mpirun yet, i guess it's not implemented in version 1.4.2.


My questions are:

Is there an equivalent flag in openmpi-1.4.2 for --no-daemonize??
If not, How could I run mpirun in order not to run in background??
Does anyone has tried this??
