global_prefs.xml: (the host's preferences)

cc_config.xml: (the client configuration options)

The following control how long the simulation runs. Duration may not exceed TimeStep*10000.
Time step:
Duration:

The following controls enable various experimental policies. The standard policy is no checkboxes enabled.

Server does EDF simulation based on current workload?

Client uses Round-Robin (old-style) CPU scheduling?
