DeNovo: Rethinking Hardware for Disciplined Parallelism

We believe that future large-scale multicore systems will require disciplined parallel programming practices, including data-race-freedom, deterministic-by-default semantics, and structured, explicit parallel control and side-effects. We argue that this software evolution presents far-reaching opportunities for parallel hardware design to greatly improve complexity, power-efficiency, and performance scalability. The DeNovo project is rethinking hardware design from the ground up to exploit these opportunities. This paper presents the broad research agenda of DeNovo, including a holistic rethinking of cache coherence, memory consistency, communication, and cache architecture.
