Evaluating Chiplet-based Large-Scale Interconnection Networks via Cycle-Accurate Packet-Parallel Simulation

Explore a conference talk from USENIX ATC '24 that delves into the evaluation of chiplet-based large-scale interconnection networks using cycle-accurate packet-parallel simulation. Learn about the Chiplet Network Simulator (CNSim), a novel tool designed to address the challenges in evaluating chiplet-based networks. Discover how CNSim's packet-centric simulation architecture and atomic-based hyper-threading mechanism accelerate simulation speed by 11× to 14× compared to existing cycle-accurate simulators. Gain insights into the implementation of heterogeneous router/link microarchitecture, hierarchical topologies, adaptive routing, and real workload traces integration. Understand the systematic evaluation of two typical chiplet-based networks and the revealed advantages and limitations of this architecture. Access the open-sourced simulator and evaluation framework to further explore this cutting-edge technology in network simulation.
