About EAS

Energy consumption of data centers has become a real issue for economic and ecological reasons.

Energy Aware Solutions S.L (EAS), a Barcelona Supercomputing Center (BSC) - University Polytechnic of Catalonia (UPC) spin off, was created in September 2020 with the aim of providing professional services to manage and optimize the data center energy using the EAR software. EAR is a European open-source system software tool for energy monitoring, management and optimization which is developed by BSC and EAS. To sustain our exponential growth, we are looking for talents to expand both the EAR software and EAS services.
