Developed and integrated non-blocking electric and magnetic field communications for the EZoni/WarpX repository, targeting improved parallel performance in multi-dimensional simulations. The work focused on enabling nowait communication across all directions, allowing overlap of data transfers and reducing overall latency. By merging Y and Z axis communication latency with X, the solution achieved up to 30% speedup on representative workloads and enhanced scalability for large-scale runs. Implementation relied on C++ and MPI, demonstrating expertise in parallel computing and performance optimization. The contribution addressed a core bottleneck in WarpX, resulting in more efficient simulation solve times without introducing new bugs.
