Abstract:Temperature rise will affect the stability and performance of multi-core processors. A temperature-aware task scheduling algorithm for real-time multi-core systems, called LTEDF (Low Thermal Early Deadline First), is proposed in this paper. In LTEDF, a HCNF ( History Coolest Neighborhood First) task allocation algorithm is employed to balance the loads. When some cores are thermally saturated, task migration is performed to alleviate thermal saturation to get more uniform power density map. A thermal aware multicore scheduling simulator(TAMSS) based on HotSpot thermal model is implemented. TAMSS simulation results show that LTEDF algorithm can not only meet real-time guarantee, but also minimize the thermal penalty. Moreover, it can create a more uniform power density map than other thermalaware algorithms, and significantly reduce thread migration frequency. ? 2010 IEEE.
