Summary

This guide provides instructions for configuring a two-node AMD Strix Halo cluster using Intel E810 (RoCE v2) for distributed vLLM inference with Tensor Parallelism. It covers hardware prerequisites, host configuration for Fedora 43, toolbox installation, network verification, cluster operation, and troubleshooting steps.

Key Takeaways

The guide provides instructions for configuring a two-node AMD Strix Halo cluster using Intel E810 (RoCE v2) for distributed vLLM inference with Tensor Parallelism.
Key components include vLLM for high-performance inference, Ray for cluster orchestration, and RCCL for fast synchronization of tensor data between GPUs.
RDMA over Converged Ethernet (RoCE v2) reduces latency from approximately 70-100µs to about 5µs, significantly improving performance for interactive token generation.
The recommended host configuration includes Fedora 43, specific kernel versions, and static IP assignments for both nodes.
