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 …

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 …

This paper presents a novel disk storage architecture called DCD, Disk Caching Disk, for the
purpose of optimizing I/O performance. The main idea of the DCD is to use a small log disk …

As we move toward the exascale era, performance variability in HPC systems remains a
challenge. I/O interference, a major cause of this variability, is becoming more important …

There is growing concern that I/O systems will be hard pressed to satisfy the requirements of
future leadership-class machines. Even current machines are found to be I/O bound for …

Performance and reliability design constraints for exascale storage systems are significant
challenges for HPC system designers. We are develo** the CODES simulation toolkit to …

The growth of computing power on large-scale systems requires commensurate high-
bandwidth I/O systems. Many parallel file systems are designed to provide fast sustainable …

With increasing complexity of HPC workflows, data management services need to perform
expensive I/O operations asynchronously in the background, aiming to overlap the I/O with …

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 …

Software Reconnaissance is a dynamic analysis technique to help programmers locate
code that they need to understand, fix, or enhance in an unfamiliar system. The technique …
