Description: An important class of scheduling algorithms is the class of dynamic priority algorithms. The most important dynamic priority algorithm is Earliest Deadline First (EDF).
Earliest-deadline-first (EDF) is good for scheduling real-time tasks in order to meet timing constraint. Earliest-deadline-first (EDF) is real-time disk-scheduling algorithms that service realtime tasks according to their deadlines.
EDF was originally designed for processor scheduling. When applied to disks, the algorithm simply selects the request with the earliest deadline for service. An advantage of this algorithm is that it is simple and easy to implement. Performance results demonstrate the effectiveness of the algorithm.

Description: High temperature will affect the stability and performance of multi-core processors. A temperatureaware
scheduling algorithm for soft real-time multi-core systems is proposed in this paper, namely
LTCEDF (Low Thermal Contribution Early Deadline First). According to the core temperature and thread
thermal contribution, LTCEDF performs thread migration and exchange to avoid thermal saturation and
to keep temperature equilibrium among all the cores. The core temperature calculation method and the
thread thermal contribution prediction method are presented. LTCEDF is simulated on ATMI simulator
platform. Simulation results show that LTCEDF can not only minimize the thermal penalty, but also meet
real-time guarantee. Moreover, it can create a more uniform power density map than other thermalaware
algorithms, and significantly reduce thread migration frequency Platform: |
