Join us as a

Intern/Master Thesis Student — DC-OXC Traffic Scheduling for Super-Node Architecture (m/f/d)

Your mission

• Study existing approaches to MoE traffic scheduling, collective communication optimization, and OCS-based interconnect architectures, build a clear understanding of how load imbalance in MoE inference leads to Alltoallv congestion and long-tail latency.

• Research and implement techniques to transform random, dynamic sparse MoE traffic into deterministic, uniform traffic patterns that OCS can efficiently handle.

• Investigate collective communication strategies that eliminate the need for frequent topology reconfiguration, leveraging optical path bandwidth to remove local hotspots and long-tail effects

• Design and prototype load-aware routing algorithms that intelligently distribute non-uniform Token traffic across limited OCS "narrow pipes.

• Develop software-level traffic smoothing mechanisms to eliminate physical-layer congestion jitter, targeting end-to-end inference latency equivalent to 100% load-balanced scenarios

Your areas of expertise

• Currently pursuing a Bachelor's, Master's degree in Computer Science, Computer Engineering, Electronic Engineering, Applied Mathematics, or a related field.

• Solid understanding of deep learning fundamentals, including neural network architectures, training/inference pipelines, and GPU computation.

• Strong background in graph theory, combinatorial optimization, linear/integer programming, or queuing theory.

• Familiarity with multi-commodity flow optimization, network flow problems, or convex optimization is a strong plus.

• Understanding of network interconnect technologies, including OCS (Optical Circuit Switching), InfiniBand, RoCE, or similar high-performance interconnects is a strong plus.

• Basic understanding of MoE (Mixture of Experts) models — how Token routing works and why it creates non-uniform communication patterns. Deep expertise is not expected, but conceptual familiarity is required

• Ability to work independently and collaboratively in a research-oriented environment
