Worked on expanding PyTorch’s distributed testing infrastructure to support Intel GPU and XPU hardware, focusing on the pytorch/pytorch repository. Over five months, ported multiple distributed and shard test cases to Intel accelerators, integrating accelerator-aware logic and dynamic backend detection using Python. Enhanced memory management and cross-device statistics by updating test harnesses to utilize new accelerator interfaces, which improved test reliability and observability across CPU, CUDA, and Intel GPU. Maintained code quality by preserving original test styles while broadening hardware compatibility, enabling earlier detection of integration issues and laying the foundation for robust distributed systems and GPU programming workflows.
