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