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

The largest-scale high-performance (HPC) systems are stretching parallel file systems to
their limits in terms of aggregate bandwidth and numbers of clients. To further sustain the …

We present a comprehensive survey on parallel I/O in the high-performance computing
(HPC) context. This is an important field for HPC because of the historic gap between …

Unmatched computation and storage performance in new HPC systems have led to a
plethora of I/O optimizations ranging from application-side collective I/O to network and disk …

A significant percentage of the computing capacity of large-scale platforms is wasted
because of interferences incurred by multiple applications that access a shared parallel file …

A key trend facing extreme-scale computational science is the widening gap between
computational and I/O rates, and the challenge that follows is how to best gain insight from …

The DOE Extreme-Scale Technology Acceleration Fast Forward Storage and IO Stack
project is going to have significant impact on storage systems design within and beyond the …

With exascale computing on the horizon, the performance variability of I/O systems
represents a key challenge in sustaining high performance. In many HPC applications, I/O is …

Supercomputer I/O loads are often dominated by writes. HPC (High Performance
Computing) file systems are designed to absorb these bursty outputs at high bandwidth …

This paper offers a solution to overcome the complexities of production system I/O
performance monitoring. We present Beacon, an end-to-end I/O resource monitoring and …
