PROFILE
Joel Jennings
Over a two-month period, contributed foundational numerical features to the google-deepmind/torax repository, focusing on efficient matrix operations for scientific computing. Developed a BlockTriDiagonal class in Python using JAX, enabling the representation and manipulation of block-tridiagonal matrices critical for discrete system solvers in computational fluid dynamics. Subsequently, implemented a solver for block-tridiagonal linear systems based on the Thomas algorithm, integrating it into the sparse linear systems workflow to accelerate simulation performance. The work emphasized algorithm design, matrix algebra, and rigorous software testing, establishing a robust numerical core that supports scalable, high-fidelity simulations and paves the way for future optimizations.
