PROFILE
Bathmatt
Contributed performance-focused features to large-scale scientific computing projects, delivering optimizations in both the EZoni/WarpX and trilinos/Trilinos repositories. Developed non-blocking electric and magnetic field communications in WarpX using C++ and MPI, enabling overlap of axis communications and reducing simulation latency for multi-dimensional workloads. In Trilinos, enhanced the Amesos2Smoother by caching temporary MultiVectors, minimizing memory allocations and improving repeated projection efficiency. Demonstrated expertise in C++ development, parallel computing, and algorithm design, with a focus on production code performance and scalability. Collaborated closely with project teams, integrating changes through code review and co-authorship to improve solver throughput and memory management.
