“The annual Lustre report is segmented into three sections: Market Dynamics; The State of Lustre in 2014; and Intersect360 Research Analysis. The report also looks at market trends around file systems, exploring the past, present and future of Lustre in Big Data.”

OpenSFS Benchmarking Working Group Releases I/O Characterization Report


“The OpenSFS Benchmarking Working Group (BWG) was created with the intent of defining an I/O benchmark suite to satisfy the requirements of the scalable parallel file system users and facilities. The first step toward this end was identified as characterization of I/O workloads, from small- to very large-scale parallel file systems, deployed at various high-performance and parallel computing (HPC) facilities and institutions. The characterization will then drive the design of the I/O benchmarks that emulate these workloads.”
