Vast volumes of data are produced by today’s scientific simulations and advanced instruments.

Lossy compression is one of the most efficient solutions to reduce storage overhead and improve I/O performance for HPC applications. However, existing parallel I/O libraries cannot fully utilize lossy compression to accelerate parallel write due to the lack of deep understanding on compression-write performance. To this end, we propose to deeply i...
CNN-based surrogates have become prevalent in scientific applications to replace conventional time-consuming physical approaches.

Today's extreme-scale scientific simulations and instruments are producing huge amounts of data that cannot be transmitted or stored effectively. Lossy compression, a data compression approach leading to certain data distortion, has been considered as a promising solution, because it can significantly reduce the data size while maintaining high data fidelity. However, the existing lossy compression methods may not always work effectively on all datasets used in specific applications because of their distinct and diverse characteristics. Moreover, the user objectives in compression quality and performance may vary with applications, datasets or circumstances. This project aims to develop a hybrid lossy compression framework to automatically construct the best-fit compression for diverse user objectives in data-intensive scientific research. Educational and engagement activities are provided to develop new curriculum related to scientific data compression and promote research collaborations with national laboratories.
Deep learning (DL) has rapidly evolved to a state-of-the-art technique in many science and technology disciplines, such as scientific exploration, national security, smart environment, and healthcare. Many of these DL applications require using high-performance computing (HPC) resources to process large amounts of data. Researchers and scientists, for instance, are employing extreme-scale DL applications in HPC infrastructures to classify extreme weather patterns and high-energy particles. In recent years, using Graphics Processing Units (GPUs) to accelerate DL applications has attracted increasing attention. However, the ever-increasing scales of DL applications bring many challenges to today's GPU-based HPC infrastructures. The key challenge is the huge gap (e.g., one to two orders of magnitude) between the memory requirement and its availability on GPUs. This project aims to fill this gap by developing a novel framework to reduce the memory demand effectively and efficiently via data compression technologies for extreme-scale DL applications. The proposed research will enhance the GPU-based HPC infrastructures in broad communities for many scientific disciplines that rely on DL technologies. The project will connect machine learning and HPC communities and increase interactions between them. Educational and engagement activities include developing new curriculum related to data compression, mentoring a selected group of high school students in a year-long research project for a regional Science Fair competition, and increasing the community's understanding of leveraging HPC infrastructures for DL technologies. The project will also encourage student interest in research related to DL technologies on HPC environment and promote research collaborations with multiple national laboratories. This project is supported by NSF under grant OAC-2034169.
The project aims to investigate state-of-the-art techniques to improve the fidelity, trust, and correctness of reduced scientific data (such as lossy compressed data) for large-scale HPC applications in terms of diverse postanalysis.
