Jordan Benjamin
Worked on the HazyResearch/ThunderKittens repository, delivering core platform enhancements focused on large language model integration, GPU pipeline optimization, and distributed system stability. Over three months, implemented end-to-end Llama model support, migrated and validated KVM runner utilities, and introduced memory and scheduling optimizations using C++, CUDA, and Python. Improved build systems, documentation, and observability through extended timing instrumentation and robust testing infrastructure. Addressed critical bugs in multi-GPU peer-to-peer initialization, ensuring reliable distributed GPU workflows. Emphasized clean code practices, defensive programming, and performance benchmarking, resulting in a more scalable, maintainable backend for high-throughput machine learning and inference workloads.

Jul 1, 2025July 2025: Primary focus on stabilizing multi-GPU workflows in HazyResearch/ThunderKittens. Delivered a targeted bug fix to prevent crashes during multi-GPU peer-to-peer initialization by guarding the peer access enablement in PyTorch utility code. This change reduces downtime and improves reliability for distributed GPU experiments, enabling faster iteration and more consistent results. Demonstrated proficiency in debugging distributed GPU setups and defensive programming, with a clean, low-risk patch linked to commit 1f795ffaebe6f5170b9ec7d745d5cb51b6ff9869.

Apr 1, 2025April 2025 for HazyResearch/ThunderKittens delivered core platform enhancements, robust bug fixes, and readiness work across the codebase. Key features include end-to-end Llama integration (start, move, full llama) with reduction logic, migration of KVM runner utilities into the ThunderKittens repo with kernel invocation support and PyVM validation, and notable improvements to build/test infrastructure and documentation to accelerate shipping and QA. Performance and scalability improvements were pursued through memory- and scheduling-focused work (BF16 GMem memory optimizations, per-head scheduling, deeper pipeline) complemented by extended timing instrumentation for profiling. A broad stability drive addressed critical correctness issues and data-path reliability, while observability gains (timings, partial timings) enabled deeper performance insight for ongoing optimization.
