PROFILE
Ming-xu Huang
Mingh contributed to NVIDIA/TransformerEngine by developing distributed training features and FP8 acceleration for large-scale deep learning. Over three months, Mingh implemented Ring Attention with context parallelism for JAX fused attention, enabling scalable multi-node communication and higher training throughput. They added FP8 AllGather support for GroupedGEMM, fixed a critical FFI stream usage issue, and enhanced distributed launch robustness using JAX multihost utilities. Their work included refining quantization with FP8 current-scaling, introducing local-Amax computation, and improving normalization precision. Mingh’s engineering demonstrated depth in distributed systems, JAX, and CUDA, delivering robust, production-ready solutions for high-performance GPU-based model training.

Sep 1, 2025September 2025 — NVIDIA/TransformerEngine: Delivered two major features enabling reliable distributed training and FP8 acceleration. 1) Distributed Launch and Allgather Robustness for Multi-Process Training: refined run-count logic and CUDA visible devices, integrated JAX multihost utilities for allgather, and expanded robust GEMM tests. 2) FP8 Current-scaling Enhancements and Amax Support for Distributed Training: lowered precision for gated-activation, aligned normalization outputs/activations to original precision, added local-Amax computation, and introduced Amax primitive into activation, normalization, and updated dense/MLP layers; fixed a quantizer error. Impact: improved stability, scalability, and throughput for multi-node FP8-enabled training. Demonstrated technologies: distributed systems design, JAX, FP8 arithmetic, Amax/local-Amax, and MLP/dense integration.
