PROFILE
Farzana Ahmed Siddique
Worked on the UVA-LavaLab/PIMeval-PIMbench repository, developing and refining cross-device APIs and performance modeling tools for memory-centric computing. Built a Prefix Sum API supporting bit-serial, CUDA, and CPU backends, ensuring correctness across architectures through targeted bug fixes and operation count recalibration. Modernized reduction command handling using C++ features like std::variant to simplify data-type management and improve maintainability. Enhanced documentation and configuration management, including HBM simulation updates and improved attribution guidance. Addressed cross-platform build issues for macOS by resolving type-casting bugs in string utilities. Demonstrated depth in C++, CUDA, and system programming, with a focus on maintainable, high-performance code.

May 1, 2025May 2025 monthly summary for UVA-LavaLab/PIMeval-PIMbench: Implemented a cross-device Prefix Sum API across bit-serial, CUDA, and CPU backends, integrated into the PIM library with device-specific variants, updated operation counts, and documentation. Fixed correctness issues (off-by-one loop and bit-serial calculation) ensuring reliable results across data types and architectures. Removed obsolete AES PIM outputs to simplify the repo. Updated HBM configurations for PIMeval/TACO/AQUABOLT simulations, adding subarray-level configs and aligning rank bandwidth with A100_80GB, improving model realism. Documentation improvements accompany performance modeling updates.
