Supercomputers are very intensive in energy consumption. Large clusters are composed of hundreds or thousands of processors working in parallel, as is easily seen, the processors are the system component that consumes the most. An indicative figure is that a standard server tripled their consumption when their processors work at 100% load. In addition, we must say that the power consumption of computers is converted into heat at a high rate, which causes that the power consumption of the

These reasons force to design new systems (data centers and computer) with the most efficient energy balance, which means to have low PUE (Power Usage Efectiveness). This article shows the PUE monitoring and control system implanted in Calendula, the FCSCL Supercomputer.
