Parallel Programming Models - Productivity and Applications for Exascale and Beyond

SPPEXA (Priority Programme “Software for Exascale Computing”) is a priority program in Germany addressing research on various aspects of HPC software, which is particularly urgent against the background that we are currently entering the era of ubiquitous massive parallelism.

The three fields, parallel programming models, HPC tools to foster productivity, and applications in numerical computing form the common interests of the SPPEXA projects MYX, ESSEX-II and DASH, and comprised the themes of the first edition of the workshop which was hold on 2017, April in Tokyo (Japan). This workshop allowed to identify opportunities for interaction between the three projects and showed the convergence between them for future collaborations. The participants agreed that it would be a good consortium of researchers for future research on software for Exascale supercomputers and beyond. Then, it was decided to organize another joint workshop in Europe with these three projects. 

The goal of this second edition of workshop is to foster collaborations between these three projects attract attendance from Europe and Japan beyond the SPPEXA projects. Furthermore, in this desire for international openness, international invited Prof. Jack Dongarra and Prof. Vassil Alexandrov will round off the scientific program of the workshop.

In addition to the invited presentations, the agenda contains contributions from the SPPEXA PIs on the recent progress made in the projects. Project members – young researchers – will present their individual results and next steps. In summary, the workshop will consist of many short talk in the order of 15 to 20 minutes (link to the program). The agenda and the social interactions are expected to make new contacts among the participants to build upon in the future.
