摘要

In this work, we evaluate the utility of adding two new ceilings to the roofline model related to PCI-E and effective Network bandwidths to provide insights into how communication impacts the performance of large-scale parallel applications. The roofline performance analysis is based on two benchmark problems: scalar dense matrix addition and dense symmetric eigen-problem with complex matrix. The ...
