Trading Off Performance for Energy in Linear Algebra Operations with Applications in Control Theory

Trading Off Performance for Energy in Linear Algebra Operations with Applications in Control Theory

We analyze the performance-power-energy balance of a conventional Intel Xeon mul- ticore processor and two low-power architectures –an Intel Atom processor and a sys- tem with a quad-core ARM Cortex A9+NVIDIA Quadro 1000M– using a high perfor- mance implementation of Gauss-Jordan elimination...
