The considerable interest in the high performance computing (HPC) community regarding
analyzing and visualization data without first writing to disk, ie, in situ processing, is due to …

Applications running on leadership platforms are more and more bottlenecked by storage
input/output (I/O). In an effort to combat the increasing disparity between I/O throughput and …

We present a high-resolution simulation of the 2004 Sumatra-Andaman earthquake,
including non-linear frictional failure on a megathrustsplay fault system. Our method exploits …

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 …

Remote procedure call (RPC) is a technique that has been largely adopted by distributed
services. This technique, now more and more used in the context of high-performance …

Large-scale simulations can produce hundreds of terabytes to petabytes of data,
complicating and limiting the efficiency of workflows. Traditionally, outputs are stored on the …

Near the dawn of the petascale era, IO libraries had reached a stability in their function and
data layout with only incremental changes being incorporated. The shift in technology …

Composition of computational science applications, whether into ad hoc pipelines for
analysis of simulation data or into well-defined and repeatable workflows, is becoming …

Growing evidence in the scientific computing community indicates that parallel file systems
are not sufficient for all HPC storage workloads. This realization has motivated extensive …

Modern simulation workflows generate and analyze massive amounts of data using I/O
libraries like Adios2 and NetCDF. Although extensive work has optimized the I/O processes …
