This workshop is the inaugural meeting in the attempt to forming a special interest group for high-performance I/O in the UK. It brings together: storage vendors, system and middleware developers, and users of data-intensive workloads in order to develop strategies for research, funding but also product development. It covers all aspects of data access and management including I/O workflow handling, parallel file systems, middleware, data compression, tuning, performance monitoring, novel interfaces, storage technology, data center perspectives. Participants present relevant RD&E in this field and discuss opportunities to bring forward the research in the UK. Talks should include challenges faced dealing with I/O and ongoing activities to overcome these challenges. Vendor talks focus on technical solutions for certain challenges accompanied by use cases demonstrating the benefit.
