OpenOptics: An Open Research Framework for Optical Data Center Networks
Yiming Lei, Federico De Marchi, Jialong Li +3
Optical data center networks (DCNs) are emerging as a promising design for cloud infrastructure. However, existing optical DCN architectures operate as closed ecosystems, tying sof…
Unlocking Diversity of Fast-Switched Optical Data Center Networks with Unified Routing
Jialong Li, Federico De Marchi, Yiming Lei +3
Optical data center networks (DCNs) are emerging as a promising solution for cloud infrastructure in the post-Moore's Law era, particularly with the advent of 'fast-switched' optic…
Optimizing Mixture-of-Experts Inference Time Combining Model Deployment and Communication Scheduling
Jialong Li, Shreyansh Tripathi, Lakshay Rastogi +3
As machine learning models scale in size and complexity, their computational requirements become a significant barrier. Mixture-of-Experts (MoE) models alleviate this issue by sele…
Nanosecond Precision Time Synchronization for Optical Data Center Networks
Yiming Lei, Jialong Li, Zhengqing Liu +2
Optical data center networks (DCNs) are renovating the infrastructure design for the cloud in the post Moore's law era. The fact that optical DCNs rely on optical circuits of micro…
