Jens Domke is a postdoctoral researcher at the Global Scientific Information and Computing Center, which hosts the TSUBAME3 supercomputer for the Tokyo Institute of Technology, Japan. He received his doctoral degree from the Technische Universität Dresden, Germany, in 2017 for his work on HPC routing algorithms and interconnects. Jens started his career in HPC in 2008, after he and a team of five students of the TU Dresden and Indiana University, won the Student Cluster Competition at SC '08. Since then, he published several peer-reviewed journal and conference articles. Jens contributed the DFSSSP and Nue routing algorithms to the subnet manager of InfiniBand. His research focus is on interconnects, topologies, and routing algorithms for HPC systems. Furthermore, he is interested in SDN networks, scheduling algorithms for parallel architectures, and performance evaluation and optimization of parallel applications.
