Chapter 5

Routing algorithms for workload consolidation

Abstract

To provide efficient, high-performance routing algorithms, a holistic approach should be taken. The key aspects of routing algorithm design include adaptivity, path selection strategy, virtual channel allocation, isolation, and hardware implementation cost; these design aspects are not independent. The key contribution of this chapter lies in the design of a novel selection strategy, the destination-based selection strategy (DBSS), which targets interference that can arise in many-core systems running consolidation workloads. In the process of this design, we holistically consider all aspects to ensure an efficient design. Existing routing algorithms largely overlook issues ...
