Tomislav,

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
mpirun pvserver

that will start the server on daviddoria.

Can anyone confirm or deny?

Thanks,

David
