Dr. Rolf RabenseifnerHead of Parallel Computing, Training & Application Services, High Performance Computing Center Stuttgart
Rolf Rabenseifner studied mathematics and physics at the University of Stuttgart. Since 1984, he has worked at the High-Performance Computing-Center Stuttgart (HLRS). He led the projects DFN-RPC, a remote procedure call tool, and MPI-GLUE, the first metacomputing MPI combining different vendor's MPIs without loosing the full MPI interface. In his dissertation, he developed a controlled logical clock as global time for trace-based profiling of parallel and distributed applications. Since 1996, he has been a member of the MPI-2 Forum and since Dec. 2007 he is in the steering committee of the MPI-3 Forum and was responsible for new MPI-2.1 standard. From January to April 1999, he was an invited researcher at the Center for High-Performance Computing at Dresden University of Technology.
Currently, he is head of Parallel Computing - Training and Application Services at HLRS. He is involved in MPI profiling and benchmarking, e.g., in the HPC Challenge Benchmark Suite. In recent projects, he studied parallel I/O, parallel programming models for clusters of SMP nodes, and optimization of MPI collective routines. In workshops and summer schools he teaches parallel programming models in many universities and labs in Germany. In January 2012, the Gauss Center of Supercomputing (GCS), with HLRS, LRZ in Garching and the Jülich Supercomputing Center as members, was selected as one of six PRACE Advanced Training Centers (PATCs) and he was appointed as GCS’PATC director.
