Prof. Brüning is one of the co-founders of EXTOLL. He is a renowned researcher in the area of computer architecture with a long track record of designing parallel hardware architectures and interconnection networks. Prof. Brüning is a professor of computer architecture at the University of Heidelberg, and co-founded and was the CEO of a company that offered several unique sequential and parallel UNIX computing systems. He has worked on numerous parallel and high-performance machines and architectures. He designed the hardware for the function-parallel machine „Starlet“ in 1983 and the node architecture for the SUPRENUM parallel machine (an initiative to build a German supercomputer from 1985 to 1990). In 1993, he architected the parallel MANNA computer based on the Intel i860 processor and custom ASICs. Until 1995, he also took part in the development of the massively parallel machine PowerMANNA based on the Motorola PowerPC620. In 2003, he presented the HPC interconnection network ATOLL, which was a precursor to EXTOLL. Within EXTOLL he sets the research strategy and direction and manages collaboration with academia.
