High-Performance I/O is currently a major problem in clusters, grids, and HPC centres due to several problems. However, it has become a strategic part of the computer architecture to achieve global computing performance, as the speed of processors and networks is increasing every day.

In this workshop we will address theoretical and practical issues related to new solutions trying to solve the I/O problem in large scale high-performance I/O systems, and also those topics related to data intensive computing and data intensive applications. The goal is to identify, discuss, and share the barriers and workarounds that have been discovered.

HIPERIO was already organized in 2006, when it attracted high interest from the community. It was a half-a-day workshop. This year we plan to extend it to a full-day workshop because in 2006, due to the restriction on the agenda for the workshop, some good papers were discarded.
