These workshops were organized by members of the Nesus Cost Action IC 1305: Network for Sustainable Ultrascale Computing, which is a follow-up of COST Actions IC0804 and IC0805 1. The goal of the NESUS Action is to establish an open European research network targeting sustainable solutions for ultrascale computing aiming at cross fertilization among HPC, large-scale distributed systems, and big data management. This network aims at contributing to glue disparate researchers working across different areas and provide a meeting ground for researchers in these separate areas to exchange ideas, to identify synergies, and to pursue common activities in research topics such as sustainable software solutions (applications and system software stack), data management, energy efficiency, and resilience. The selected papers cover very important scientific issues encountered nowadays such as the following: CPU/GPU execution, system-on-chip programming, parallel algorithms taking into account various constraints (energy, communication, etc.), programming models, and so on. We really hope that the reader will enjoy this high-quality issue, and we are sure that she/he will find it highly relevant to the state-of-the-art of today's heterogeneous and parallel computing.
