The High Performance Computing (HPC) community aimed for many years to increase performance regardless of energy consumption. Until the end of the decade, a next generation of HPC systems is expected to reach sustained performances of the order of exaflops. This requires many times more performance compared to the fastest supercomputers of today. Achieving(More)
The High-Performance Computing (HPC) community aimed for many years at increasing performance regardless to energy consumption. However, energy is limiting the scalability of next generation supercomputers. Current HPC systems already cost huge amounts of power, in the order of a few Mega Watts (MW). The future HPC systems intend to achieve 10 to 100 times(More)
Energy consumption on systems that have a continuous power source is tightly-related to both the computing time of an application and its required CPU load. Considering the scope of HPC applications which commonly have a time precision in nano or milliseconds, we observe a lack of systems that combine appropriate sampling rate, low intrusiveness and low(More)
The power consumption of High Performance Computing (HPC) systems is an increasing concern as large-scale systems grow in size and, consequently, consume more energy. In response to this challenge, we propose two variants of a new energy-aware load balancer that aim at reducing the energy consumption of parallel platforms running imbalanced scientific(More)
