Sandy,

Now Vardan's jobs run successfully on farm node, we can start to plan to set up a new queue "exclusive", or some other name if anyone has a better name. We can move 6 farm12xxx nodes into this queue. Later operation team can add or remove nodes in the queue. 

To use the same track for multi-core jobs, I suggest that we create a new routing queue "production". All tracks used to map to prod64 queue will change to routing queue "production". This routing queue will forward to new "exclusive" queue if the ppn >= 16. Otherwise jobs will go to old prod64 queue.

I think we can create these two new queues now, this will not interrupt the current queuing/running jobs (please verity this). After this change, all new jobs will still go to prod64 queue. Once I test the new queue, I will update the database Track table to map to production queue. Then Vardan's job (20 core) will go to "exclusive" queue, every other jobs still go to old "prod64" queue.
