About EAS
Power consumption is a critical topic for Data Centers today both from an economical and environmental perspective.
Energy Aware Solutions S.L. (EAS) ( has been created in September 2020 to provide a software solution to energy efficiency by reducing the power consumption of existing data centers while hurting its performance as little as possible.
EAS technology is based on EAR software which is a European open-source system software tool developed since 2016 by the two EAS creators Dr. Julita Corbalan (EAS CTO) & Dr. Luigi Brochard (EAS CEO). Julita is an associate professor at University Polytechnic of Catalonia and a researcher at the Barcelona Supercomputing Center. Luigi was an IBM Distinguished Engineer when he created the energy aware scheduler feature for LoadLeveler and then Spectrum LSF. EAR monitors, manages and optimizes the Data Center energy by controlling transparently and real time both the applications and the servers on which the applications run. EAS technology is installed in several large and medium size European HPC Data Centers and demand is rising. We are also involved in different European projects to support the development of new EAR features and we are working closely with Lenovo, Intel and AMD.
