Workshop on Storage Challenges in the UK

The Special Interest Group of High-Performance I/O in the UK (SIG IO UK – Join our mailing list) organizes this workshop to bring together: users of data-intensive workloads, storage vendors, and system and middleware developers, in order to identify common challenges, to develop strategies for research and funding but also product development.

The workshop series generally covers all aspects of data access and management including I/O workflow handling, parallel file systems, middleware, tuning, performance monitoring, novel interfaces, storage technology, and data center perspectives. The workshop is primarily organized as a series of talks and group discussion slots.

This particular workshop focuses on exchanging information about challenges and the ongoing efforts to overcome them aiming to bring forward RD&E and the use of storage systems (in the UK). Users present their challenges faced dealing with I/O and ongoing RD&E to overcome them. Vendor talks focus on technical solutions for certain challenges accompanied by use cases demonstrating the benefit.

We welcome the submission of talks and short papers (in LaTeX article format) that summarize the challenges and ongoing effort in different institutions that we will lead to a joint paper submitted to Springer Lecture Notes in Computer Science as part of the ISC-HPC proceedings.

This workshop is sponsored by DDN and powered by the Virtual Institute for I/O and ESiWACE 1).

The SIG-IO-UK is a loose consortium of people and institutions that share a common interest in High-Performance I/O. The SIG exchanges information revolving around the topic covering, but not limited to, I/O challenges, RD&E, and solutions on the market. We develop whitepapers raising awareness in the importance of I/O, describing the state of the art in the UK, aim to derive research and funding opportunities but also aid product development.

Jean-Thomas Acquaviva successively worked for Intel, the University of Versailles and the French Atomic Commission (CEA). He participated to the creation of their joint laboratory the Exascale Research Centre, where he led the Performance Evaluation Team. Today he’s actively contributing the development of the DDN Storage Advanced Technology Centre in France. Jean-Thomas has hands-on experience in the HPC ecosystem, with positions in start-up, large research public institutions, SME or global organizations. He has been a direct contributor to the ETP4PH Strategic Research Agenda and he’s chairing two conferences on high performance storage.

Julian Kunkel is a Lecturer at the Computer Science Department at the University of Reading. He manages several research projects revolving around High-Performance Computing and particularly high-performance storage. Besides his main goal to provide efficient and performance-portable I/O, his HPC-related interests are: data reduction techniques, performance analysis of parallel applications and parallel I/O, management of cluster systems, cost-efficiency considerations, and software engineering of scientific software.
