Just in time for LUG 2014, the OpenSFS Benchmarking Working Group (BWG) has
released its new 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


As part of the characterization, the BWG released a survey at the
Supercomputing Conference in 2012, to solicit participation and collect data
on file systems and workloads in HPC centers. This paper, which summarizes
the data collected and our analysis, is now available on the OpenSFS web
site at
