Short bio
Thomas Zeiser heads the Systems & Services group of NHR@FAU and HPC4FAU since end of 2020. Thus, he is the Chief Operating Officer HPC at NHR@FAU. In the “NHR Betreiberausschuss” he is the deputy for NHR@FAU.
Major topics currently are
- transition from serving FAU only to a national center
- operation of all the HPC systems
- procurement of new systems and adaption of the infrastructure in the facility
- financial controlling of NHR@FAU’s budgets
- supporting the planing of a new data center building
Thomas Zeiser studied chemical engineering at the Friedrich-Alexander Universität Erlangen-Nürnberg, and did his PhD theses with Prof. Durst at the chair of fluid mechanics (LSTM). In 2004 he joined the HPC group of RRZE as senior research scientist and still spent time on lattice Boltzmann methods. Other research interest have been large-scale simulations in general, the evaluation of new HPC hard- and software, but also the efficient operation of HPC systems. Quite some time has also regularly been spent on the procurement of RRZE’s HPC systems. Thomas also implemented the first job-based job and performance monitoring for RRZE’s HPC systems.
Thomas regularly serves as reviewer for different journals or compute time commissions of different HPC centers. He is also one of the local organizers in the Sarntal for the Ferienakademie of TUM, FAU, and Universität Stuttgart.
