We implemented a mixed-precision, nested recursive Cholesky algorithm for GPU Matrix Processing Units (NVIDIA H200, AMD MI300X) using Julia. With a hierarchical precision method, we maximize throughput while maintaining numerical stability. Our recursive SYRK achieves a 14x speedup over cuBLAS, leading to a 5.32x overall speedup for Cholesky over cuSOLVER FP64. The solver leverages Julia’s multiple dispatch to provide a portable interface for HPC.
