The high-performance computing I/O stack has been complex due to multiple software
layers, the inter-dependencies among these layers, and the different performance tuning …

Abstract Space Weather is the study of the dynamics of the coupled Solar‐Terrestrial
environment, as these dynamics impact technological systems and human activity. This …

Over the past four years, the Big Data and Exascale Computing (BDEC) project organized a
series of five international workshops that aimed to explore the ways in which the new forms …

Parallel File Systems (PFSs) are frequently deployed on leadership High Performance
Computing (HPC) systems to ensure efficient I/O, persistent storage and scalable …

Contemporary high-performance computing (HPC) applications encompass a broad range
of distinct I/O strategies and are often executed on a number of different compute platforms …

Large-scale applications typically spend a large fraction of their execution time performing
I/O to a parallel storage system. However, with rapid progress in compute and storage …

We report our experiences porting Spark to large production HPC systems. While Spark
performance in a data center installation (with local disks) is dominated by the network, our …

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 …

I/O performance is a critical aspect of data-intensive scientific computing. We seek to
advance the state of the practice in understanding and diagnosing I/O performance issues …

Writing high-performance solvers for engineering applications is a delicate task. These
codes are often developed on an application to application basis, highly optimized to solve a …
