Topology- and message-size-aware algorithm selector for AllReduce, AllGather, and ReduceScatter. Automatically selects optimal algorithm (Ring/Tree/NVLS/PAT) based on message size and communication domain. Includes: - Pre-calibrated algo characteristics for H800 GPU topology - Intra-node (NVLink) and inter-node (RDMA) selection modes - Determinism-aware selection - Full selection table generation (240+ configurations) - Visualization heatmap generation Co-Authored-By: Claude <noreply@anthropic.com>
