[condor-users] Myrinet

[Joel Hernandez <joelh@xxxxxxxxx>]

We have two eight node dual cpu clusters (louie and duey).  Users submit 
their jobs on louie and when all the nodes are busy, they start to flock 
and run on duey.  This was working fine until we recently installed 
Myrinet on louie but not on duey.  In order to get Condor to run using 
IP over Myrinet, I modified the condor_config.local files on each of the 
louie nodes to reflect the Myrinet IP address for the 
NETWORK_INTERFACE.  However, since we do not have Myrinet on the duey 
cluster, the head node on duey and the head node on louie must still use 
the 100 Mbps ethernet address to comunicate.  This would require two 
values for the NETWORK_INTERFACE on the head node on louie.  It appears 
that Condor does not support such a thing.  Is there another way to get 
the head node on a cluster to communicate via two network interfaces?

Thanks,
Joel
