Guest seminar by Olivier Aumage.
Overview
Abstract:
Runtime systems in HPC are paradoxical in nature. They come as an extra software layer to be boldly inserted right on the critical path between applications and the hardware resources that such applications would like to take advantage of to their full capacity. Yet, HPC runtime systems manage to bring performance benefits to some applications, and even additional perks such as portability, performance portability, or energy footprint minimization. This talk proposes a discussion on HPC runtime system design principles to shed some light on how this paradox is resolved in practice.
