When Parallelism Pays Off: Cohesion-Aware Task Partitioning for Multi-Agent Coding

arXiv:2606.00953v1 Announce Type: new Abstract: Multi-agent Large Language Model (LLM) systems offer a way to decompose complex tasks, such as coding, through parallelization and context isolation. However, adding agents in practice introduces inter-agent communication overhead, which incurs extra cost and can sometimes offset the efficiency gains. We formalize multi-agent orchestration as a graph partitioning problem that captures the communication-to-computation trade-off: task decomposition can shorten critical-path computation, but cross-agent dependencies require costly context transfer.

Why this matters
Why now

The proliferation of multi-agent LLM systems necessitates efficient orchestration, and this research addresses a critical bottleneck: communication overhead.

Why it’s important

Optimizing multi-agent LLM performance is crucial for advancing AI capabilities and integrating them into complex workflows, impacting productivity and the scope of automation.

What changes

Approaches to deploying multi-agent systems will evolve to explicitly account for communication costs, leading to more efficient and scalable AI-driven solutions.
