Hi All

Am trying to run a parallel molecular simulation from the directory containing the executable (using only available cores on the local cpus) on Mac Lion and keep getting an apparent firewall error that cannot be resolved. I am entering:

mpirun  -np 2 -e ./mpierr1 dock6.mpi -otherinput

and get transient (too quick to Allow) notification messages 'Do you want the application "orterun" to accept incoming network connections? Clicking Deny may limit....... The setting can be changed in the firewall pane......."

The mpirun message says:
--------------
Initializing MPI Routines...
Initializing MPI Routines...

--------------

I can specify orterun as a trusted app with "sudo /usr/libexec/ApplicationFirewall/socketfilterfw -t /usr/local/bin/orterun". Before, and after allowing firewall access by orterun and dock6.mpi I get the following by viewing the /var/log/appfirewall.log:

Jan 24 00:48:45 Dans-Mac Firewall[23513]: orterun is listening from 0.0.0.0:50722 proto=6
Jan 24 00:48:45 Dans-Mac Firewall[23513]: dock6.mpi is listening from 0.0.0.0:50723 proto=6
Jan 24 00:48:45 Dans-Mac Firewall[23513]: dock6.mpi is listening from 0.0.0.0:50724 proto=6
Jan 24 00:48:45 Dans-Mac Firewall[23513]: dock6.mpi is listening from 0.0.0.0:1024 proto=6
Jan 24 00:48:45 Dans-Mac Firewall[23513]: dock6.mpi is listening from 0.0.0.0:1025 proto=6

It appears that something is trying to start but cannot, and I dont know what else to try. Can anyone suggest how this might be resolved?

Thanks much for any input!
