The aim of the Workshop on Performance and Scalability of Storage Systems, is to present state-of-the-art research, innovative ideas, and experience that focused on the design and implementation of HPC storage systems in both academic and industrial worlds, with a special interest on performance analysis.

2017 Workshop: June 22 at 2:00 PM

Room Gold 1

Frankfurt Mariott, Frankfurt Germany



The Challenge

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, 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.

These factors will probably lead to significant loss of performance predictability, leaving storage system designers, application developers and the storage community at large 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.

The Solution

Held in conjunction with the International Supercomputing Conference (ISC), the intention of WOPSSS is to encourage discussion of these issues through submissions of researchers or practitioners from both academia and industry.

Topics of interest include (but not limited to):

  1. Storage systems modeling and analysis tools
  2. Feed-back and empirical evaluation of storage systems
  3. Application I/O characterization
  4. Parallel I/O and storage systems (consistency, caching, replication, reliability and fault recovery overhead)
  5. Network challenges and storage systems (scalability, QoS, partitionability)
  6. Low-latency storage systems usability and analysis (memory-only, Flash, NVRAM, and Storage Class Memory)
  7. File system design
  8. Operating system stack optimization
  9. Cloud and distributed storage

Non-Volatile Memory for Next Generation I/O
Dr Michele Weiland, EPCC - University of Edinburgh

Abstract: The H2020 funded NEXTGenIO project is developing a prototype computing platform that uses on-node non-volatile memory to bridge the latency gap between DRAM and disk, and dramatically improve I/O performance for HPC and data intensive applications. In addition to the hardware that will be built as part of the project, NEXTGenIO is developing the software stack (from OS and runtime support to programming models and tools) that goes hand-in-hand with this new hardware architecture. This talk will look at how the new technology could be used to benefit a wide range of use cases.


The Role of Parallel File Systems in the Era of Burst Buffer and Exascale
Gabriele Paciucci, Scalable Datacenter Solutions group, Intel

Abstract: New technologies are becoming mainstream to address the I/O requirements of the next generation of HPC clusters. Is the burst buffer the solution for a TB/sec I/O requirement or for, finally, solve the checkpoint use case? Are the upcoming NVRAM changing the game and the design of the next generation of clusters? Which will be the role of the “legacy” parallel file systems?  In this presentation we will try to answer those questions and discuss the vision of Intel for the future of the HPC storage.
