And what does that mean?? What command did you type, on which machine, 
and what response did you see?

The master node is where you run condor_submit to queue a job, condor_q 
to examine the queue, condor_status to look at what the worker machines 
are doing.

Are you saying you don't have access to the master node? Well, it is 
possible to run these tools on one machine and ask them to query a 
different master node. But this adds extra command-line options. Also 
you would need to set up access permissions so that access from that 
other machine was allowed.

If I were you, I'd start simple. One master node, a number of execute 
nodes, everyone logs into the master node to submit jobs.

condor doesn't, as far as I know, support any form of "live" migration. 
If you're using standard universe then you have checkpointing, so I 
suppose it's possible to terminate a job and have it restart on another 
node from that checkpoint, but I don't use standard universe so I don't 
really know (I use vanilla universe)

I've tried to explain this as simply as I can, but if I've failed then 
I'm sorry, I don't think I can put it any more simply than I already have.

Also, please remember to reply to the list, not just to me personally.

Brian.
