Collective Communication for Distributed LLM Systems: Planning, Runtime Adaptation, and Computation Coordination

This paper presents a tutorial-style, collective-centric taxonomy for collective communication, which organizes recent advances into three layers: communication planning, which generates topology-aware collective schedules; communication execution and adaptation, which maps these schedules onto GPU runtimes and hardware in real clusters; and computation-communication coordination, which turns collective optimization into end-to-end training and inference benefits.

HyLink: Harnessing PCIe and Dedicated Interconnects for Efficient Collective Communication

HyLink is introduced, a two-layer collective communication framework, including a PCIe CCL module and a Multipath Orchestrator module that provides a CPU-driven Domain-Specific Language (DSL) for multi-stage data flows and an auto-pipelined transfer engine for host-side routing and SIMD-accelerated reduction.
