Abstract: The next generation of supercomputers will be exascale (10¹⁸ floating-point operations per second) computer systems. These systems will help scientists and engineers tackle extremely complex high-performance computing (HPC) and artificial intelligence (AI) problems for critical societal challenges, such as climate change, water management, advanced manufacturing, and vaccine and drug design. However, due to the gap between ever-increasing compute power and limited storage capacity and I/O bandwidth, scientists and engineers must create intelligent and effective methods to efficiently manage massive amounts of data generated by HPC and AI applications for fast storage and transmission. This talk will introduce our promising solution – error-bounded lossy compression – that can significantly reduce the data sizes while maintaining high data fidelity for post-analyses in HPC and AI applications. The talk will cover the design, optimization, and use of our error-bounded lossy compression to advance HPC and AI systems (e.g., GPU-based heterogenous systems) for large-scale data processing applications (e.g., HPC simulations and AI model training).
