Description
We are entering the era of thermally-bound computing: Advanced and costly cooling solutions are needed to sustain the high computing densities of high-performance computing equipment. To reduce cooling costs and cooling overprovisioning, dynamic thermal management (DTM) strategies aim at controlling the device temperature by modulating online the performance of processing elements. While operating systems allow the migration of threads between cores, in HPC systems the threads of parallel applications are pinned to the allocated cores at start-time to avoid job-migration overheads. In this scenario state-of-the-art DTM solutions, which use thermal models to map jobs to cores, are based on long-term predictions to map the most critical job to the coldest core. Instead, turbo-mode and DVFS controllers are based on short-term predictions to squeeze the thermal capacitance allowing for short period …
