Colloquium talk in the Computer Science and Data Science programs on Smart and Efficient Data Management.
Jinzhen Wang, Assistant Professor (Brooklyn College of CUNY)
Extreme-scale simulations running on leadership-class supercomputers are crucial for scientific advancements in various domains. Yet, the relentless pursuit of higher resolution and fidelity has led to an exponential surge in the volume of scientific data stemming from these simulations. Consequently, the formidable tasks of storage and analysis have emerged as pressing challenges.
To address this challenge, lossy compression has emerged to reduce the storage footprint. However, a critical concern revolving around the accuracy preservation of lossy compression, especially for downstream analyses has impeded the widespread integration of lossy compression into the high-performance computing workflow.
In this talk, I will introduce my Ph.D. research toward smart and efficient scientific data management. For efficient data management, it is crucial to achieve the most benefit from lossy data compression. I will introduce our work on performance modeling of data compression, utilizing both analytic and deep learning approaches.
In pursuit of smart data management, we aim to determine whether we can achieve better data compression with deep learning approaches. I will present our work on 1) scientific data compression with Autoencoder network and 2) minimizing the I/O overhead of scientific data retrieval using deep neural networks.
Finally, I will conclude by outlining potential research directions and future work aimed at fostering smarter and more efficient HPC scientific data management.
