Abstract:   The Workshop on Performance and Scalability of Storage Systems (WOPSSS) aims to present state-of-the-art research, innovative ideas, and experience that focus on the design and implementation of HPC storage systems in both academic and industrial worlds, with a special interest on their performance analysis. Presently, two factors are affecting the design of new storage architectures. First, the race for Exascale is pushing storage systems to a scale unseen in current practice. Second, new technologies, such Storage Class Memories (SCM), are causing disruptions in the market. In the past, systems could be seen as three well identified components, each with its own order of magnitude: DRAM – nanosecond, network – microsecond, storage – millisecond. Now, this hierarchy and its isolation between components is becoming irrelevant because storage components are filtering down to faster levels (e.g., SCM latency is in nanoseconds, and NVMe storage is in microseconds). Thus, the behavior of data storage and its access is more complex to analyze. Furthermore, Exascale systems will be heterogeneous, harnessing different kinds of nodes – thin and fat compute nodes, I/O delegation nodes, storage node – leading to complex networks and traffic management problems. We consider that this will lead to significant loss of performance predictability. This will leave storage system designers, application developers and the storage community at large in the difficult situation of not being able to precisely detect bottlenecks, evaluate the room for improvement, or estimate the matching of applications with a given storage architecture. WOPSSS intends to encourage discussion of these issues through submissions of researchers or practitioners from both academic and industrial worlds.

Targeted Audience
Considering the list of topics WOPSSS can be meaningful to a large spectrum of both researchers and practitioners. From application developers concern by the lack of scalability due to I/O bottleneck, to storage library researchers as well as the storage system designers. We expect the different communities on the I/O critical path to have some interest in getting insight on the performance. We expect a specific interest from storage system managers who are nowadays confronted to the already difficult task to correlate performance issues with applications.
