Abstract:   This workshop aims to focus on the design and implementation of HPC storage systems with a special interest on their performance analysis. Presently, two factors affect 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 among 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, beside the scale, the heterogeneity of Exascale systems will lead to complex networks and traffic management problems. These factors will probably lead to significant loss of performance predictability, leaving the storage community in the difficult situation of not being able to detect bottlenecks precisely, evaluate the room for improvement, or estimate the matching of applications with a given storage architecture.  

Targeted Audience 
WOPSSS intends to encourage discussion of these issues through submissions of researchers or practitioners from both academic and industrial worlds. In, last year edition most of the people attending were academic, some being well established senior researchers, some others young Ph.Ds.
