Power-Efficient Computing: Experiences from the COSA Project
Running two kinds of benchmarks on the various CPUs of the COSA CNAF cluster. (a) and (b) show the results of the HPCG benchmark: HPCG score (weighted GFLOP/s) on (a) and ratio between HPCG score and absorbed power on (b), for increasing number of CPU cores. (c) and (d) show GFLOP/s and power ratio for the home-made MATMUL benchmark.
