Abstract: This paper presents an energy-efficient workload scheduling methodology for multi-core multi-processor systems under actively cooled environment that improves overall system power performance with minimal response time degradation. Using a highly efficient miniature-scale refrigeration system, we show that active-cooling by refrigeration on a per-server basis not only leads to substantial power-performance improvement, but also improves the overall system performance without increasing the overall system power including the cost of cooling. Based on the measured results, we present a model that captures different relations and parameters of multi-core processor and the refrigeration system. This model is extended to illustrate the potential of power optimization of multi-core multi-processor systems and to investigate different methodologies of workload scheduling under the actively cooled environment to maximize power efficiency while minimizing response time. We propose an energy-ef ficient workload scheduling methodology that results in total consumption comparable to the spatial subsetting scheme but with faster response time under the actively cooled environment. The actively cooled system results in ≥29% of power reduction over the non-refrigerated design across the entire range of utilization levels. The proposed methodology is further combined with the G/G/m-model to investigate the trade-off between the total power and target SLA requirements. (More)
