|---|---|---|
This paper presents a new scheme for jointly and dynamically allocating and scheduling tasks with both periodic and aperiodic time constraints in distributed real-time system. The scheme includes a new allocation algorithm, a new scheduling algorithm and a heuristic scheduling algorithm. The new allocation algorithm is called Classified-Processing- Nodes Allocation (CPNA). In CPNA algorithm, we divide the processing nodes (PNs) into two sets: Set A and Set P. Set A is used to accept aperiodic real-time tasks. Periodic real-time tasks are dispatched to Set P. The partition to PNs is not fixed but flexible and autoadaptive. The new dynamic scheduling algorithm is called First Committed First (FCF) algorithm, which is used to schedule periodic real-time tasks. In our scheme, we use a heuristic scheduling algorithm to schedule aperiodic real-time tasks. To evaluate our scheme, we compare CPNA with Equal-Processing- Nodes Allocation (EPNA), FCF with RMS through experiments. The experimental results show that our scheme with CPNA and FCF is more efficient than the scheme with EPNA and RMS. |
