Velocity Scheduler (vsched), Batch Scheduler
Please note:
Connecting to testlogin from off campus: If you are not on the Cornell campus, first make a remote connection to ctcloginb/c and then connect to testlogin.
This is similar to what you do now to connect interactively to machines in the batch
system. Once the new system image is installed on ctclogina/b/c, then you will able
to connect to them directly.
