About the Role
This role involves porting high-performance electromagnetics kernels to the GPU, starting with the Biot-Savart magnetic-field calculation in cfsem, CFS’s open-source Rust library. The work will extend to include cross-platform GPU kernel variants with Python bindings.
Key Responsibilities
- Port high-performance electromagnetics kernels to the GPU.
- Hold code to a scientific-correctness bar by checking GPU kernels against cfsem’s existing unit tests and CPU versions.
- Determine accuracy of methods for engineers relying on results to design superconducting magnets.
- Measure and report GPU performance by benchmarking speed and accuracy against optimized multithreaded Rust CPU kernels.
- Present recommendations on where GPU acceleration is beneficial.
- Ship public open-source work by integrating new kernels behind cfsem’s existing Python interface.
- Contribute to a public Rust/Python project.
