Summary
🤩
Rockstar🎓
Top SchoolBernhard Gruber is a Senior System Software Engineer at NVIDIA specializing in CUDA core libraries (CUB, Thrust, libcu++) with 11 years of experience in high-performance C++ and GPGPU programming. Finishing a PhD at TU Dresden on data layout optimization for heterogeneous architectures, he combines deep research on memory/access abstractions with hands-on performance engineering across CUDA, OpenCL and SYCL. His background includes mission-critical embedded control software at CERN and industrial CAD/CAM simulation, and notable open-source contributions to projects like Vc, alpaka, and the PIConGPU codebase. A voting member of the ISO C++ committee and an experienced C++ instructor, he brings strong library design, refactoring and cross-platform QA skills and a knack for making complex parallel code maintainable. Based remotely from Lake Traunsee, he is curious about C++ toolchains, SIMD, emerging systems languages and growing into a public-facing standards and conference speaker role.
