Summary
🤩
Rockstar🎓
Top SchoolGiannis Gonidelis is a software engineer with eight years of experience specializing in C++ and CUDA for high-performance computing and core libraries. Now based in San Francisco, he develops CUDA C++ core libraries at NVIDIA after contributing to the C++ Standard Library for Parallelism and Concurrency (HPX) and working on reference Senders/Receivers implementations. His work spans algorithm design, iterator/sentinel modernization for C++20, and test automation—skills honed through research at LSU and internships at NVIDIA and AMD. An active open-source contributor, he helped adapt HPX’s parallel algorithms to modern standards and improved key algorithms like for_each, remove, and transform. Notably, his background bridges academic performance analysis of task-based runtimes with production-grade GPU library development, giving him a rare combined perspective on AMT benchmarking and low-level parallel runtime engineering.
