Re: [condor-users] Network in Linux-Cluster and MPI

[Mark Silberstein <marks@xxxxxxxxxxxxxxxxxxxxxxx>]

Well, I would not mix these two things. 
Why do you use 0.0.0.0 settings for NETWORK_INTERFACE? If you have Linux
and SUN pools connected in any way via network, you should not need to
configure Condor to listen on more than one NW interface. Can you be
more specific about your network topology to understand this?
I expect that you would get the same communication problem for whatever
job you run, since ALL Condor communications would not work with
NETWORK_INTERFACE parameter set to 0.0.0.0
