Jiri Vyskocil developed a GPU-accelerated generalized eigenvalue solver for the cp2k/cp2k repository, targeting large-scale matrix computations. He integrated cuSOLVER’s sygvd routine, creating a new C API and a Fortran wrapper to expose the solver within the codebase. His implementation included a size-based dispatch mechanism in Fortran, automatically selecting the GPU-accelerated path for matrices of size 64x64 or larger while retaining a safe fallback for smaller cases. Leveraging C, Fortran, and CUDA, Jiri’s work improved performance and scalability for numerical linear algebra tasks, providing a robust foundation for future GPU computing enhancements in scientific simulations.
February 2026 monthly performance summary focusing on the cp2k/cp2k repository. Delivered targeted enhancements to enable scalable, distributed CPU/GPU workflows by adding NCCL support to CuSolverMP and introducing version-detection logic to conditionally link to NCCL or CAL depending on CuSolverMP version. These changes improve throughput, scalability, portability, and deployment flexibility for large-scale simulations.
