As far as I know - simply, hit the "Stop" button on Mac OSX Sharing
pref-panel for Firewall, on the local and remote systems both (one is
my PowerBook G4, the other my PowerMac G5).
Sounds like this should be sufficient.
- Do you have only one TCP interface on both machines? If you have
more than one, we can try telling Open MPI to ignore one of them.
Interesting idea. The remote machine has two ethernet ports
(PowerMac) and the local machine has ethernet and airport. Only one
port should be enabled on each, but the PowerBook airport is what I
use at home so maybe it didn't get properly disabled when I switched
to my work settings. Since the call to MPI-send seems to hand on the
local host, it may be an attempt to use the airport (wireless)
connection. How to I tell Open MPI to ignore a particular interface?
Check out http://www.open-mpi.org/faq/?category=tcp#tcp-selection --
it talks about the MCA parameters you can use to specify different
networks. For example, on my powerbook, en0 appears to be my wired
connection.
Let us know what happens.
