DescriptionEvolving and new storage technologies introduced over the last few years are causing increasing complexity for HPC data management. Hence, analyzing, comparing, or even predicting the performance of different HPC machines and storage systems has become more complicated. To address this challenge, the community developed a benchmark that lead to the creation of the competitive IO-500 list. The benchmark consists of several data and metadata benchmarks to identify performance boundaries for optimized and suboptimal applications. In addition to offering different ways to compare storage systems, the list collects information about storage system design to help system designers make informed trade-offs when specifying new storage requirements.
The development of the benchmark is powered by the Virtual Institute for I/O (http://vi4io.org), which provides a platform for I/O enthusiasts for exchanging information, fosters international collaboration in the field of high-performance I/O, and tracks the deployment of large storage systems by hosting comprehensive information about high-performance storage systems.
The general purpose of this BoF is to foster the storage community in understanding the performance characteristics of HPC storage. The session leaders will give a series of brief talks that seed the subsequent discussions:
1) The release of the new IO-500 list and highlights. Observed issues are sketched and alternatives to overcome these are discussed with the community.
2) The virtual institute and the comprehensive data center list.
3) Roadmaps with features are sketched inviting the community to prioritize the features.
The outcome of this BoF will steer the direction of these community efforts.
