Postdoctoral Appointee - HPC and Machine Learning

Argonne National Laboratory

Lemont, IL

Job posting number: #7084353

Posted: August 31, 2021

Application Deadline: Open Until Filled

Job Description

We are seeking self-motivated and independent postdoc researchers with strong background on Machine Learning, system design, and coding skills (C/C++). The selected candidate will work closely with the SZ compression team at Argonne to develop the cutting-edge lossy compression libraries/tools practically for the scientific community. The SZ team (http://szcompressor.org) is the leading team in the error-bounded lossy compression domain. The flagship software - SZ has been verified as one of the best error-bonded lossy compressors in the community by many domain scientists independently. Joining SZ team will have exceptional opportunities to collaborate with top-tier scientists in different domains and use cutting-edge supercomputers (Aurora, Summit, etc.).

Today's scientific applications are producing extremely large volumes of data, which are causing serious issues including storage burden, I/O bottlenecks, communication bottlenecks, and insufficient memory. Error-controlled lossy compression has been recognized as one of the most efficient solutions to resolve the big scientific data issue. Existing state-of-the-art lossy compressors, however, are all developed based on fixed/static compression models or pipeline, which cannot adapt to diverse data characteristics and sophisticated user-requirements. In this project, we will develop a scalable dynamic data reduction framework, which can optimize lossy compression for various use-cases dynamically and efficiently. The key techniques include using ML/DL to explore the diverse correlations of high-dimensional science datasets, using ML/DL to identify the best-qualified data compression model dynamically, using ML/DL to optimize the parameter configurations of various compression methods, using ML/DL to denoise datasets and/or recovering missing features for reconstructed data.
