Code Analysis
9 files read ยท 3 roundsA distributed GPU inference serving system for Diffusion Transformers that implements multi-dimensional parallelism (data, CFG, sequence, tensor, pipeline) with ILP-based task scheduling and custom ring/ulysses attention kernels for models like Flux, CogVideoX, HunyuanVideo, and SD3.
Strengths
Genuine distributed systems engineering with real ILP optimization for GPU scheduling, proper multi-dimensional parallelism decomposition, and custom distributed attention implementations with KV cache support.
Weaknesses
README is completely misleading (describes a simple GUI app), no visible test suite, significant code duplication, and extremely large monolithic files (76KB scheduler, 114KB engine) that hurt maintainability.
