SPMW: A Grid-Based Programming Model for Scalable Accelerator Design

arXiv:2611.12944v1 Announce Type: cross Abstract: Modern accelerators specialize recurring computation and replicate it across regular hardware structures to achieve high performance. Sustaining this parallelism requires equally deliberate data delivery. Yet design tools often express these structures as sequential programs or flatten them into separate hardware modules and connections. This obscures shared patterns and leads to repeated compiler work. We introduce Single Program, Multiple Connected Work Units (SPMW), a grid-based programming model for scalable accelerator design that makes grid regularity a first-class abstraction. SPMW decouples local work-unit behavior from grid connectivity and data delivery.
