During a three-month period, Daniel Thomas developed and optimized image analytics and benchmarking tools for the UVA-LavaLab/PIMeval-PIMbench repository. He engineered a C++-based, PIM-accelerated BMP histogram computation pipeline, introducing chunked processing and OpenMP parallelization to handle large images efficiently. Daniel also established a robust benchmarking framework for Global Average Pooling (GAP), integrating C++ and PyTorch implementations to enable cross-platform performance comparisons and correctness verification. His work included refactoring command-line argument parsing and build systems, improving usability and reproducibility. Through careful code review and iterative improvements, Daniel delivered reliable, maintainable solutions that advanced PIM-enabled image processing and benchmarking workflows.

Dec 1, 2024December 2024 (UVA-LavaLab/PIMeval-PIMbench) focused on reliability and performance benchmarking for image analytics on PIM hardware. Key outcomes include: robust histogram processing for large images via input chunking and cleanup (addressing stability and performance) and the first iteration of a GAP benchmark with cross‑platform verification. The GAP work includes C++ implementations for PIM and CPU verification plus a PyTorch-based Python baseline for performance comparison, establishing a foundation for evaluating GAP on PIM hardware. These efforts improve production reliability, enable objective cross-hardware comparisons, and set the stage for future performance-driven optimizations. Technologies demonstrated include C++, PyTorch (Python), benchmarking methodologies, and code-quality improvements through review fixes.
