DARPA Spectrum Challenge Q&A

1. Q: Is it permissible to test the ssh public key mechanism prior to the reservation time?
   A: Please feel free to test the keys against gw.orbit-lab.org
2. Q: Are the resource times for our schedule in EST or in our team's local time which is MST?
   A: All the resource times in the schedule email are in EST (Eastern Standard Time).
   
3. Q: I would like to find out the procedure to to access a specific domain when I have been assigned two domains which overlap in time.
   A: All omf commands accept -t flag which specifies a set of resource (nodes). That set can be specified as either list of nodes or a path to file containing a resource set. So if you have multiple virtual domains reserved, system:topo:all would refer to all nodes contained in all domains. If you just want to work with a subset of nodes, you could simply list them on a command line. For example, if you have approved reservation for zDC01 and DCGNUR01 and wanted to say image only nodes in DCGNUR01 you would issues
