Optimizing the SSD Burst Buffer by Traffic Detection
Xuanhua Shi, Wei Liu, Ligang He +3
Currently, Burst buffer has been proposed to manage the SSD buffering of bursty write requests. Although burst buffer can improve I/O performance in many cases, we find that it has…
A Software-Defined QoS Provisioning Framework for HPC Applications
Neda Tavakoli, Yong Chen
With the emergence of large-scale data-intensive high-performance applications, new I/O challenges appear in the efficient management of petabytes of information in High-Performanc…
A Cross-Layer Solution in Scientific Workflow System for Tackling Data Movement Challenge
Dong Dai, Robert Ross, Dounia Khaldi +4
Scientific applications in HPC environment are more com-plex and more data-intensive nowadays. Scientists usually rely on workflow system to manage the complexity: simply define mu…
A Software-Defined Approach for QoS Control in High-Performance Computing Storage Systems
Neda Tavakoli, Dong Dai, John Jenkins +3
High-performance computing (HPC) storage systems become increasingly critical to scientific applications given the data-driven discovery paradigm shift. As a storage solution for l…
Client-side Straggler-Aware I/O Scheduler for Object-based Parallel File Systems
Neda Tavakoli, Dong Dai, Yong Chen
Object-based parallel file systems have emerged as promising storage solutions for high-performance computing (HPC) systems. Despite the fact that object storage provides a flexibl…
