HPC Performance Engineer
Phone: +1 510 495 8134
Weile Wei is an HPC Performance Engineer at NERSC, where he works on benchmarking runtime systems, researching C++ parallel algorithms, modernizing software engineering practices, and exploring future programming models. Before joining NERSC, he was a Research Scientist at Meta, focusing on software infrastructure performance optimization and scaling. Weile has a Ph.D. in Computer Science from Louisiana State University, where he studied distributed GPU memory optimization, HPX runtime system, performance portabilities, and asynchronous task-based programming.
