Abstract:   Traditionally, HPC has treated I/O like an afterthought – for a long time, highest compute performance and efficiency took precedence for developing systems and applications. Today, applications are becoming more diverse and complex, and are handling ever larger amount of data. HPC systems are growing rapidly in size, and with the need to minimise system energy use, the significance of I/O has fundamentally changed: providing highly scalable and efficient parallel I/O is now seen as a major challenge for HPC systems and system software, and a prerequisite for achieving Exascale levels of delivered performance. At the same time, progress in network and memory/storage technology provides new opportunities to address this challenge. The session unites leading HPC experts to discuss their analysis of I/O related challenges that HPC and the rapidly emerging field of high performance data analytics (HPDA) face, present potential hardware and software solutions for dealing with the extreme volumes of data involved in HPC and HPDA in a scalable and highly efficient way, and examine how emerging technologies (like nonvolatile storage class memory) can best impact. The scope encompasses system architecture and components, the I/O system software stack and APIs for HPC and HPDA applications. The proposed BoF will continue the discussion started at ISC 2016. Presenters will share the progress of significant I/O innovation projects in Europe (DEEP­ER, NEXTGenIO and SAGE projects), and worldwide (Intel, Seagate). A panel­-style discussion with the audience will contribute to a consolidated view of the field and its evolution.

Targeted Audience
The BOF targets operators of large HPC systems, developers of HPC and HPDA applications, as well as system SW (with focus on I/O layers) and system architects. The discussion will cover the challenges to overcome for truly scalable and efficient I/O, existing technology and research, and the impact of emerging technologies (like in the nonvolatile memory and interconnect areas). The discussion will be moderated by Hans-­Christian Hoppe and Michele Weiland. The presentations and minutes of the discussion will be made publicly available on the NEXTGenIO project website.
