Important Changes Compared to ikt

  1. You only get what you ask for, regardless of the resources available on the node. If you ask for 1 CPU, you'll only get one. If you ask for 1GB of RAM, you'll only get 1GB.
  2. You don't get the same set of nodes all the time.
  3. No occasional preemption in ckpt (formerly bf queue) for the moment
