A technique for optimizing attention mechanism computations in transformer-based language models improves computational efficiency during both prefill and decode phases. The approach unequally partitions attention operations across multiple streaming multiprocessors of a hardware processing unit (e.g., such as a graphics processing unit, or GPU) to maximize hardware utilization. By leveraging the associative property of online softmax calculation as a reduction operation and employing stream-K style decomposition, the technique enables parallelization across all modes of the attention matrix, including the context length dimension. This allows for efficient distribution of computational workload across available GPU resources while ensuring equal total work allocation. The approach delivers significant speedup over existing methods, particularly for long context lengths, by maintaining near 100% GPU occupancy through optimal workload distribution and single-kernel execution.
