Summary
🤩
RockstarGuillermo Marcus is a Research Scientist at NVIDIA in Berlin with over five years of experience accelerating scientific applications on specialized hardware. He brings deep expertise in computer architecture, parallel systems, GPU programming (CUDA/OpenCL), and low-level languages like VHDL, C/C++, and FORTRAN, applied to both system design and high-performance research code. At NVIDIA he contributes to production research and OptiX software, translating algorithmic ideas into optimized implementations for clusters and GPUs. An active open-source contributor, he has helped develop NVlabs' Sionna library—improving OFDM modules, resource grid demapping, and 5G channel-coding examples—bridging ML research needs and robust library design. Colleagues rely on him for pragmatic, performance-first solutions that make advanced communication-system research reproducible and production-ready.
