ADAPTME: Operating System Support for Adaptive Performance and Thermal Management

Thermal constraints in high performance computing environments are becoming a major issue for systems’ designers which is tackled with different approaches. In addition, the skyrocketing complexity of computing systems of the near future is sought to become unmanageable leaving the question open on how to continue to improve the performance of the computing of tomorrow. In this work it is proposed an advancement in the context of operating system-based, local Dynamic Thermal Management (DTM) technique deeply rooted in the Autonomic Computing (AC) initiative called ADAPTME, a simultaneously performance and thermal aware scheduler aimed at server environments with general purpose (both batch and interactive) workloads. After implementing the system as a patch for a commodity open source Operating System (OS), the work is compared to the state of art, resulting in lower average running temperature and slowdowns.
