DGEMM benchmark code While peak performance numbers look great on data sheets, most designers also want to know what the sustained performance is with a familiar benchmark. DGEMM is a matrix-matrix multiplication added to an existing value. The product AB (matrix A multiplied by matrix B) is given by the following equation: The HPC Challenge benchmark consists of several pieces, each of which explores the performance of different aspects of the system. In the following code, each function runs a single benchmark, and returns a row table that contains performance results.

We present an experimental experience on tuning DGEMM code on the Fermi architecture. A micro-benchmark analysis of Fermi architecture is used to guide program optimizations. The benchmark makes a connection between Fermi’s architectural features and … The improved DGEMM performance is said to be for large square and reduced matrix sizes. ROCm 2.1 is also timed quite nicely for the new Radeon VII. There doesn't appear to be any notable changes on the ROCm OpenCL front, such as allowing SPIR-V support. It's also not mentioned if they have addressed any of the performance shortcomings in select cases compared to their Radeon PAL OpenCL driver.
