Abstract :
We evaluate the power consumption of three key kernels from several tuned dense linear algebra libraries on three general-purpose multi-core processors and a graphics processor, representative of the state-of-the-art in computing technology. The results of this study provide basic insights on the energy scalability of multi- and many-core designs and multi-threaded software as the building blocks of future EXAFLOPS systems.
