MoonMath AI Open-Sources a HIP Attention Kernel for AMD MI300X That Beats AITER v3 on Every Shape and Rounding Mode

MoonMath AI has released an open-source HIP attention kernel designed to optimize performance on AMD MI300X hardware. By utilizing one-instruction assembly wrappers and an eight-wave pipeline, the implementation surpasses the efficiency of AMD’s own AITER v3 across all tested configurations and rounding modes.
