OpenCL has become the favored framework for emerging heterogeneous devices and FPGAs, owing to its versatility and portability.

    However, OpenCL-based math libraries still face challenges in fully leveraging device performance.

    When deploying high-performance arithmetic applications on these devices, the most important hot function is General Matrix-matrix Multiplication (GEMM).

    This study presents a meticulously optimized OpenCL GEMM kernel.
