Extreme Data Workshop 2018 Forschungszentrum Jülich, 18 – 19 September 2018 Proceedings

We report on a two-day workshop in September 2018 which brought together scientists from different disciplines, computer engineers, and hardware vendors to discuss the challenges of data handling in the upcoming exascale era. Several aspects of extreme data management were brought up in the participants’ presentations, and some commonexpectations and issues were identified in a plenary discussion. This paper summarizes the workshop presentations and discussions and reflects on likely and necessary developments in HPC infrastructures and services for meeting the domain sciences demands in the future. The paradigm change from compute centric to data centric HPC applications and the increasing complexity of HPC systems will also require much greater efforts in training next generation scientists and computer engineers
