Summary
🤩
Rockstar🎓
Top SchoolRobert Mijakovic is an experienced researcher and software engineer with a doctorate from Technical University Munich and over a decade working at the intersection of HPC, MPI, and system software. He has driven performance analysis and optimization efforts on multi-/many-core processors, GPUs and large clusters, and has hands-on expertise with Spack and EasyBuild—contributing backend and DevOps improvements to the widely used Spack package manager. His roles at LRZ and Huawei show deep experience tuning MPI stacks (OpenMPI, Intel MPI), InfiniBand fabrics, and deploying monitoring and regression frameworks for supercomputers like SuperMUC-NG. Comfortable across C/C++, CUDA/OpenCL, FPGA (VHDL) and automation tooling (Ansible, ReFrame), he blends low-level optimization with production-grade packaging and deployment. A less obvious strength is his track record of collaborating with hardware vendors to diagnose and fix vendor-level bugs, bridging research insights into real-world HPC operations.
