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

Scheduling policy options:

Client uses Recent Estimated Credit scheduling?
(default: debt-based scheduling)

Server does EDF simulation to predict deadline misses?
(default: approximate method)

Client uses only round-robin CPU scheduling?
(default: round-robin and EDF hybrid)
