ESSA 2024 Note (about Extreme-Scale Storage and Analysis)
ESSA 2024: 5th Workshop on Extreme-Scale Storage and Analysis
Keynote: HPC and Databases Revisited — Jay Lofstead (Sandia National Laboratories)
Paper:
1, The impact of asynchronous I/O in checkpoint-restart workloads — Hariharan Devarajan, A. Moody, D. Dai, C. Stanavige, E. Gonsiorowski, M. McFadden, O. Faaland, G. Kosinovsky, K. Mohror
Compare the different ways of checkpoint (threads, async I/O) and identify the interference for checkpoint.?
2,? Benchmarking variables for checkpointing in HPC Applications — Xiang Fu, Xin Huang, Wubiao Xu, Shiman Meng, Weiping Zhang, Luanzheng Guo, Kento Sato
A workflow is developed to identify the variable (by considering their read/write semantic and context) in the program to check-point.
3, Extending the Mochi Methodology to Enable Dynamic HPC Data Services — Matthieu Dorier, Philip Carns, Robert Ross, Shane Snyder, Rob Latham, Amal Gueroudji, George Amvrosiadis, Chuck Cranor, Jerome Soumagne?
Online the configuration of RPCs (e.g., add resources and remap resources) for Mochi (https://mochi.readthedocs.io/en/latest/). During the reconfiguration, the data could be needed to be migrated.? Need to provide service during the reconfiguration and failures.?
4, Adaptive Per-File Lossless Compression of Floating-Point Data — Andrew Rodriguez, Noushin Azami, Martin Burtscher?
LC framework (https://userweb.cs.txstate.edu/~burtscher/LC/) generates lossless compression algorithms. Population-based heuristic/genetic algorithm to find best compression algorithms.?
5, Optimizing Forward Wavefield Storage Leveraging High-Speed Storage Media — Jo?o Speglich, Navjot Kukreja, George Bisbas, átila Saraiva, Jan Hückelheim, Fabio Luporini, John Washbourne?
Wavefield simulations have forward and backward steps. Each time step has output data. NVM I/O is explored to support I/O (3D cube) from wavefield simulation.? Compression and GPU direct storage (work in future).
6,? The Art of Sparsity: Mastering High-Dimensional Tensor Storage — Bin Dong, Kesheng Wu, Suren Byna?
