Markus Hilger
HPC Engineer at MEGWARE Computer Vertrieb und Service GmbH
Berlin, Germany
Summary
🤩
Rockstar🎓
Top SchoolMarkus Hilger is an HPC engineer based in Berlin with 15 years of experience designing, administering and optimizing large-scale high performance computing and storage environments. He has led HPC projects at IBM—contributing to SuperMUC deployments, HPSS administration and authoring IBM Redbooks—and now applies that deep systems expertise at MEGWARE. Markus combines low-level infrastructure skills (cluster health checks, monitoring for 10k+ node systems, energy-efficiency tuning) with pragmatic backend and database engineering demonstrated by performance-driven contributions to open-source projects like RocketMap and xCAT. He is equally at home fixing SQL and schema issues as he is architecting resilient cluster services, and brings a practical, operations-first mindset to complex technical bids and emergency protections. An unexpected strength is his track record of translating hands-on benchmarking and intern projects into published operational guidance and tooling for production HPC.
