A new research paper details a method for optimizing transformer attention inference using the Mathematics of Arrays (MoA). The paper presents four memory-efficient artifacts, including a single-query decode DNF that algebraically eliminates the K^T buffer, achieving specific DRAM traffic results. It also introduces a C/OpenACC GPU kernel with exact floating-point arithmetic and a multi-step KV-cache with efficient append operations. Furthermore, the research derives Grouped-Query Attention (GQA) and Multi-Query Attention (MQA) to reduce KV traffic, with all methods verified against PyTorch's scaled_dot_product_attention. AI
