Constructor Detail

UUniFastDiscardTaskSetGen

public UUniFastDiscardTaskSetGen(ITaskGenerator taskGen,
                         int nbTask,
                         int nbProc,
                         double utilization,
                         double energyUtilization,
                         long Pr,
                         long emax,
                         int deadlineModel,
                         boolean offset,
                         boolean allowEnergy)

Creates a new random Taskset generator based on the UUniFast-Discard algorithm.

Parameters:

taskGen - the corresponding random task generator.

nbTask - the number of tasks to generate.

nbProc - the number of processor on which the task set will be scheduled.

utilization - the total processor utilization.

deadlineModel - the model for the deadlines (deadlineModel < 0 for constrained deadlines, deadlineModel == 0 for implicit deadlines and deadlineModel > 0 for arbitrary deadlines).

offset - true to randomly generate offset (0 <= O_i <= T_i). false otherwise (O_i = 0).
