Description
Title : Hermes - Towards an Ultimate High-Performance Algorithm for Cosmic Statistics of Large Data Sets
Speaker：Longlong Feng
Abstract:
Driven by the need for fast and efficient algorithms in cosmic statistics to handle the massive data volumes from ongoing and forthcoming galaxy surveys, we present the first public release of Hermes (HypER-speed MultirEsolution cosmic Statistics) — an open-source, parallelized, and GPU-accelerated Python package. At its core, Hermes implements the MRA-CS (MultiResolution Analysis for Cosmic Statistics) framework. This talk will provide a concise overview of the mathematical foundations and core algorithms behind Hermes, demonstrate its performance through numerical tests, and highlight its broad potential for extracting cosmological information from next-generation galaxy surveys.
Bio：
Feng Longlong, Professor of Physics at Sun Yat-sen University, Prof. Feng received his bachelor’s degree in physics from the University of Science and Technology of China (USTC) in 1982, followed by a master’s degree from USTC’s Center for Astrophysics in 1985. He earned his Ph.D. in astronomy from the Department of Astronomy at Nanjing University in 1990. After completing his doctorate, he began his academic career at USTC, where he worked until 2003. He then joined the Purple Mountain Observatory as the principal researcher of the Galactic Astronomy and Cosmology Group. Since 2014, he has been a professor in the School of Physics and Astronomy at Sun Yat-sen University.
Prof. Feng’s research interests span a broad range of topics, including relativistic astrophysics, galactic astronomy and cosmology, and computational astrophysics.
