MixNet: A Runtime Reconfigurable Optical-Electrical Fabric for Distributed Mixture-of-Experts Training

2025

Mixture-of-Expert (MoE) models outperform conventional models by selectively activating different subnets, named experts, on a per-token basis. This gated computation generates dynamic communications that cannot be determined beforehand, challenging the existing GPU interconnects that remain …

Towards Optimal Rack-scale µs-level CPU Scheduling through In-Network Workload Shaping

2025 · Rare & Special e-Zone (The Hong Kong University of Science and Technology)

>Rack-scale CPU scheduling has emerged as a promising direction to accommodate the increasing demands for microsecond-level services. However, prior work suffers from both inaccurate load balancing in the network and complex yet sub-optimal scheduling within …
