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 (as of 5.10.13) is no checkboxes enabled, and the 'Normal' DCF policy.

Server does EDF simulation based on current workload?

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

Client uses old work fetch policy?

Duration correction factor: Normal : Stats : Dual : None
