FBench: A Flexible Benchmark for CFG-Based What-If Exploration of HPC I/O Patterns
Zhaobin Zhu, Chen Wang, Kathryn Mohror +1
The I/O performance of large-scale HPC applications depends on a complex interplay of access patterns, middleware optimizations, and file system configurations. To systematically e…
Kilometer-Scale E3SM Land Model Simulation over North America
Dali Wang, Chen Wang, Qinglei Cao +9
The development of a kilometer-scale E3SM Land Model (km-scale ELM) is an integral part of the E3SM project, which seeks to advance energy-related Earth system science research wit…
Recorder: Comprehensive Parallel I/O Tracing and Analysis
Chen Wang, Izzet Yildirim, Hariharan Devarajan +2
This paper presents Recorder, a parallel I/O tracing tool designed to capture comprehensive I/O information on HPC applications. Recorder traces I/O calls across various I/O layers…
Formal Definitions and Performance Comparison of Consistency Models for Parallel File Systems
Chen Wang, Kathryn Mohror, Marc Snir
The semantics of HPC storage systems are defined by the consistency models to which they abide. Storage consistency models have been less studied than their counterparts in memory…
ML-based Modeling to Predict I/O Performance on Different Storage Sub-systems
Yiheng Xu, Pranav Sivaraman, Hariharan Devarajan +2
Parallel applications can spend a significant amount of time performing I/O on large-scale supercomputers. Fast near-compute storage accelerators called burst buffers can reduce th…
