Summary
👤
Senior🎓
Top SchoolIoannis Magkanaris is an HPC Performance Engineer based in Zurich with nine years of hands-on experience optimizing high-performance software across CPU and GPU architectures. He has driven performance and tooling at Blue Brain/EPFL—working on a C++ neuronal simulator with OpenACC, CUDA, MPI and vectorized CPU backends—and now applies that expertise at CSCS. His background spans computer architecture, parallel computing, embedded systems, operating systems and VLSI, allowing him to bridge low-level hardware-aware optimization with higher-level scientific workflows and containerized deployments. He has a proven record of producing readable, production-ready C++ and Python tooling used by scientists, including maintaining a DSL transpiler and end-to-end simulation toolchains. Curious by nature, he pairs a rigorous engineering mindset with a broader cultural perspective from international collaboration and a habit of exploring diverse interests like photography and music. This combination makes him effective at translating complex performance problems into practical, reproducible solutions for research computing.
