Chenhsu Bai developed and integrated a Conjugate Gradient (CG) solver into the pyabacus.hsolver module within the deepmodeling/abacus-develop repository. He implemented the CG algorithm in C++ and exposed it to Python using Pybind11, ensuring seamless integration with the existing solver framework. His work included updating example scripts and expanding the test suite to validate the new solver path and maintain regression safety. By enabling CG as a solver option, Chenhsu Bai enhanced the scalability and performance of the module for large linear systems, demonstrating depth in scientific computing, numerical methods, and cross-language development between C++ and Python.
Month: 2024-11 — Delivered Conjugate Gradient (CG) solver integration in the pyabacus.hsolver module for the deepmodeling/abacus-develop repository. Implemented CG in C++ with Python bindings, integrated it into the existing solver framework, and updated examples and tests to support and exercise the CG path. No major bugs fixed this period. This work broadens solver capabilities for larger systems, enabling faster convergence and more robust performance in production workflows.
