First French-Japanese-German Workshop on Programming and Computing for Exascale and beyond

Embassy of France in Tokyo - April 5th 2017 - TOKYO


High performance computing is a key topic that empowers innovation and competitiveness in order to answer many of the technical challenges we are currently facing that stand at a crossroad between big data and HPC. These systems are able to find actual solutions to the greatest struggles of our societies, in the fields of health and environment, in the industry and in the services we provide.

China, the USA, Japan and Europe have engaged in the race for next-generation supercomputers: Exascale, which is expected to reach an unprecedented level of performance with a capacity of more than a billion of billions floating operations per second. This actually means: more than a hundred times the computing power of existing systems.

But the path to Exascale is extremely challenging, on both hardware and software aspects, if we are willing to answer its inherent issues of power consumption, resilience, performance and operation. New programming paradigms, algorithms, languages and tools are required to answer this formidable challenge.

Following the “Extreme Performance Computional Science” workshop held in April 2015 in Tokyo, the French “Maison de la simulation”, RIKEN, and the Embassy of France in Japan are organizing this French-Japanese-German workshop, in order gather the Computer Science community and the users of simulation and massive data analysis. The current state of French-Japanese-German collaboration in the field will be presented, especially from the perspective of the SPPEXA program, which is funded by national agencies across the three countries (DFG, ANR and JST). This event will also be an opportunity to envision together new leads that could harbor new collaborations.
