File system metadata is the data in charge of maintaining namespace, permission semantics
and location of file data blocks. Operations on the metadata can account for up to 80% of …

The exponential growth of digital information is imposing increasing scale and efficiency
demands on modern storage infrastructures. As infrastructure complexity increases, so does …

We present GekkoFS, a temporary, highly-scalable burst buffer file system which has been
specifically optimized for new access patterns of data-intensive High-Performance …

Many scientific fields increasingly use high-performance computing (HPC) to process and
analyze massive amounts of experimental data while storage systems in today's HPC …

Storage backends of parallel compute clusters are still based mostly on magnetic disks,
while newer and faster storage technologies such as flash-based SSDs or non-volatile …

The availability of non-volatile main memory (NVMM) has started a new era for storage
systems and NVMM specific file systems can support extremely high data and metadata …

The I/O forwarding architecture is widely adopted on modern supercomputers, with a layer of
intermediate nodes sitting between the many compute nodes and backend storage nodes …

Currently, information and communication technologies are going in advance, allowing
more information to be distributed globally via the internet superhighway. While being …

Large-scale parallel applications are highly data-intensive and perform terabytes of I/O
routinely. Unfortunately, on a large-scale system where multiple applications run …

We present PAIO, a framework that allows developers to implement portable I/O policies and
optimizations for different applications with minor modifications to their original code base …
