NEST: Network- and Memory-Aware Device Placement For Distributed Deep Learning

arXiv:2603.06798v2 Announce Type: replace Abstract: The growing scale of deep learning demands distributed training frameworks that jointly reason about parallelism, memory, and network topology. Prior works often rely on heuristic or topology-agnostic search, handling communication and memory separately. Without per-device memory awareness, these methods typically ensure feasibility post hoc by sharding parameters and activations across many devices, increasing synchronization, inflating communication, and underutilizing compute-limiting scalability and efficiency on real datacenter networks.

Why this matters
Why now

The increasing scale and complexity of deep learning models are pushing the limits of current distributed training frameworks, necessitating more efficient resource management strategies.

Why it’s important

Improved network- and memory-aware device placement directly impacts the efficiency and scalability of AI model training, reducing costs and accelerating development cycles for advanced AI systems.

What changes

This research proposes a methodology to overcome existing bottlenecks in distributed deep learning by jointly optimizing for parallelism, memory, and network topology, leading to more efficient utilization of compute resources.
