14 * - Create a bunch of tasks
15 * - schedule only a subset of them (init, A and D)
16 * - run the simulation
17 * - Verify that we detect which tasks are not scheduled and show their state.
18 * The scheduled task A sends 1GB. Simulation time should be
19 * 1e9/1.25e8 + 1e-4 = 8.0001 seconds
20 * Task D is scheduled but depends on unscheduled task C.
