Scheduling Parameters and Scheduling Criteria for Thermal Aware Process Scheduler

Abstract

In recent years, as the technology escalated to meet consumer demands for computing, communication and entertainment, the issue of power consumption and heat generation has become a primary concern for the system designers. Today, it is the time to rethink and renovate the technology with the consideration of power consumption and heat generation. This study discusses the cause and adverse effects of heat generation and rise in temperature of processors. Furthermore, the study sheds light on the measures adopted by processor vendors at hardware level and numerous methodologies suggested by the researchers at the level of operating system to lessen the generated heat. This study compiles major work done until now in the field of thermal aware process scheduler, thereby suggesting thermal scheduling parameters, thermal scheduling criteria and thermal aware load balancing policy that should be considered while designing and evaluating thermal aware process schedulers. In order to validate the correctness of the suggested thermal scheduling parameters, an experiment was performed on Intel i5 machine by modifying the Linux Completely Fair Scheduler (CFS). The modified Linux CFS integrates one of the suggested parameters in the existing CFS and showed positive results when evaluated for the proposed thermal scheduling criteria.
