Re: [condor-users] Myrinet - similar problem

["Michael Nuhn" <nuhn@xxxxxxxxxxxxxx>]

Hi,

I don't have a solution but I think I have the same problem.

I have recently installed Condor on a Beowulf cluster to do workload
management on the nodes. The central manager is on the front end. If the
nodes are all busy but there are more jobs in the queue I want them to flock
to another Condor pool. The problem is that the nodes on the beowulf are in
a different IP address space than the rest of the computers here. The
central manager on the front end is configured to use the NIC on the network
of the nodes of the cluster. But in order to flock to a different pool
outside of the beowulf it would have to use a different NIC.

So I am also looking for a way to make the central manager of Condor
communicate over two NICs. Does anyone know how to configure it like that?

Thanks in advance,
Michael.
