PROFILE
Panagiotis Kourdis
Panagiotis Kourdis contributed to PyTorch and related repositories by building features that enhance hardware integration, performance profiling, and developer transparency. He improved the intel/torch-xpu-ops project by making PyTorch template symlink handling robust against repository moves, using CMake and Python to reduce build breakages. In huggingface/torchtitan, he expanded profiling tools to support Intel PVC GPUs and XPU devices, enabling deeper performance analysis. For pytorch/pytorch, he instrumented the build system in C++ and Python to expose XPU and XCCL configuration details, and clarified distributed backend documentation. His work demonstrated depth in backend development, build systems, and distributed systems.
