You are both correct. If you simply type "mpirun pvserver", then we will execute pvserver on whatever machine is local.
However, if you type "mpirun -n 1 -H host1 pvserver", then we will start pvserver on the specified host. Note that mpirun will still be executing on your local machine - but pvserver will be running on the specified host.
I'm a newbie, so forgive me if I ask something stupid:
why are You running ssh command before mpirun command? I'm interested in
setting up a paraview server on a LAN to pos-tprocess OpenFOAM
Just a total newbish comment: doesn't the mpirun in fact call for the
ssh anyway? And if pvserver is to be run on multiple machines and is
programmed in Open MPI shouldn't
mpirun -np procNumber -H host1,host2,host3 pvserver
be enough to get it going, as well as any other parallel program? Again,
please excuse my newbiness.
As is probably apparent from my email(s), I am very new to all of this as well.
From my understanding, to start the server on cloud3 from my machine (daviddoria), you must use the command
ssh cloud3 mpirun pvserver
If you use simply
that will start the server on daviddoria.
Can anyone confirm or deny?
