THE WORKSHOP ON PERFORMANCE AND SCALABILITY OF STORAGE SYSTEMS (WOPSSS)
Third WOPSSS Workshop Held jointly with ISC, Frankfurt, Germany. June 28th, 2018
**Submission Deadline: April 20, 2018**Click here for details.
STATE-OF-THE-ART RESEARCH & INNOVATION, COMING TOGETHER
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.
The arrival of new storage technologies and scales unseen in previous practice 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.
The workshop is held in conjunction with the ISC-HPC during the ISC workshop day. Note that the attendance of ISC workshops requires a workshop pass.
WOPSSS is embedded into a full-day program for I/O that we organize with the HPC-IODC: HPC I/O in the Data Center Workshop team. We will build a program with a joint morning session with keynote talks and best papers and then diverge into two independent workshops in the afternoon. You can learn more at last year's workshop web page.
All accepted papers will be published in the Proceedings by Springer. Extended versions of the best papers will be published in the ACM SIGOPS (http://www.sigops.org/osr.html) journal
** Registration & Venue **
The workshop does not have a separate registration site. Attendees need to use the registration system provided by ISC'17 (http://www.isc-hpc.com/registration.html) WOPSSS is organized in conjunction the International Supercomputing Conference (http://www.isc-hpc.com), Frankfurt, Germany.

** Submission Guidelines **
• Papers need to be submitted via Easychair (http://easychair.org/conferences/?conf=wopsss18)
• Authors are invited to submit papers are required to be formatted in Springer single column LNCS style (http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0) and within 10 pages, excluding the references.
•The submissions are "single-blind", i.e. submissions are allowed to include the author names.
The steering committee has a French bias, since this workshop took its roots as the extension of a similar initiative already running in France.

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