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

[Degi Baatartsogt <baatarts@xxxxxxxxxxxxxxxxx>]

Hi Mark,

my problem is, that we have here Linux-Cluster (Beowulf). So our Linux
Host has two Interfaces. Thatsway i'm trying to use NETWORK_INTEFACE.  I'm
not sure what kind of address i should use. But i tried all possibilities.
But as i understand, we cant solve this problem till we get the source
codes. Is that right?
