Summary
🤩
Rockstar🎓
Top SchoolSam Gross is a software engineer with 14 years of experience based in New York, currently building systems at Meta and previously co-founding Jam Labs. He specializes in low-level back-end engineering for ML and deep learning frameworks, contributing substantial compatibility, performance, and CUDA optimizations to influential projects like Torch, cuDNN bindings, and PyTorch vision and examples. His work spans ML model implementations (ResNet, VGG, Inception), GPU-accelerated layers and data-parallel improvements, and interpreter-level concurrency efforts such as GIL-free Python and pybind11 thread-safety. Comfortable across C/C++, Lua, and Python, he combines production-grade systems thinking with research-adjacent model engineering—an unusual blend that enables both core runtime fixes and high-level model integrations.

ML Engineer
ML EngineerContributions:28 commits, 27 PRs, 40 pushes in 3 years 10 months
Contributions summary:Sam made several contributions focused on improving the ResNet model implementation. These changes included adding support for checkpointing to save and load model states, incorporating a pre-activation ResNet definition, and addressing issues in the data processing pipeline such as aspect ratio jitter. They also fixed errors in the code related to computing top-5 accuracy and shareGradInput usage, ensuring the model ran correctly and efficiently.

Multithreaded Python without the GIL
Role in this project:Back-end Developer
Back-end DeveloperContributions:6 releases, 2 reviews, 984 commits in 3 years 5 months
Contributions summary:Sam contributed to the `nogil` project, which focuses on multithreaded Python without the Global Interpreter Lock (GIL). Their commits primarily address low-level implementation details related to atomic operations and compiler compatibility. The user implemented and refined atomic operations for various data types, added support for GCC builtin atomics, and fixed a bug in the `platform.python_compiler()` function. They also updated the bundled `pip` to work with the modified Python environment.
