Power Consumption of GPUs from a Software Perspective

10 pages, Publié à ICCS 2009International audienceGPUs are now considered as serious challengers for high-performance computing solutions. They have power consumptions up to 300 W. This may lead to power supply and thermal dissipation problems in computing centers. In this article we investigate, using measurements, how and where modern GPUs are using energy during various computations in a CUDA environment
