Amanda Liang

Amanda Liang contributed to the AI-Hypercomputer/maxtext and maxdiffusion repositories, focusing on deep learning model optimization and quantization workflows. She enhanced GMM throughput and memory efficiency by merging gating kernels and introducing configurable input buffers, and enabled FP8 quantization for distributed DeepSeek training, all using Python, JAX, and advanced data processing techniques. Amanda also improved the maintainability of quantization rules by refactoring FP8 pipeline logic and restoring stable group-size handling. Her targeted bug fixes in WAN quantization for maxdiffusion stabilized transformer assignments, reducing production risk. The work demonstrated depth in distributed systems, algorithm optimization, and robust, auditable code delivery.

February 2026 (2026-02) — AI-Hypercomputer/maxtext Overview: Focused on performance optimization and quantization support to boost throughput and scalability for GMM workloads and DeepSeek training. Delivered two feature sets that improve memory efficiency, reduce kernel launches, and enable FP8 quantization in distributed training. Key features delivered: - GMM Performance Optimizations: Configurable input buffer counts and gating kernel merge to increase GMM throughput and reduce kernel executions. Commits: d5b9a6c7f8e1b3b0c696fd34a74d0134baa63f9f; 3c4d81d366be37372b008461f870ac0e9692d6d2. - FP8 Support in DeepSeek Batch Split: Enabled FP8 quantization in batch split config for DeepSeek, improving distributed training efficiency by optimizing gradients and weights handling in forward/backward passes. Commit: bf6374972bd7b69f94dc7edf91edf0d6641bbfdf. Major bugs fixed: No explicit major bugs fixed documented in this scope. Stabilization efforts were delivered as part of performance work (kernel merges and quantization paths) to reduce runtime issues and improve reliability. Overall impact and accomplishments: These changes enhance performance, scalability, and cost-efficiency. The GMM optimizations reduce memory pressure and kernel launch overhead, enabling higher throughput on GMM workloads. FP8 quantization in DeepSeek batch split improves parallel training efficiency, enabling faster iterations in distributed training environments. Together, these deliver tangible business value by accelerating model training and inference workflows and enabling larger-scale experiments with existing hardware. Technologies/skills demonstrated: GPU kernel optimization, memory management, kernel fusion/merging, FP8 quantization, distributed training configuration, commit-based development and traceability, performance-focused software engineering.
