One of the main problem with clusters is their very high power consumption. Coupled with a powerful air conditioning system, a cluster consumes an average of 300 watt per machine, even when the cluster is unused, leading to a significant waste of energy.
The aim of the écoGrappe project is to design and implement a cluster management system which takes into account the energy consumption of the different components of a cluster to conserve energy depending on the workload of the cluster.
The écoGrappe project is based on Kerrighed operating system originally designed at INRIA, whose company Kerlabs ensures continuity of development and industrialization. Using the configurable global scheduler of Kerrighed, our goal is to unify and extend the techniques explored in different research areas to offer a complete and broad scope energy conservation system. This system will consist of the Kerrighed operating system and prototype modules scheduling tasks depending on energy consumption policies.
