The German Climate Computing Centre (DKRZ) is the central data processing facility for the German climate and Earth system modelling and is one of the leading facilities in this area. DKRZ operates supercomputers in the highest performance class, modern high-performance clusters and graphics systems as well as one of the largest data and archive systems worldwide. DKRZ participates in many national and international projects aiming to improve the infrastructure for climate modelling. Through its research group on scientific computing DKRZ is linked to the department of informatics of the University of Hamburg. We are hiring a
Scientific Programmer in the Field of
High Performance Computing (all genders)
Within the research-project Monsoon-2.0 the climate model ICON will be used to perform time-slice global storm-resolving (2.5 km) simulations of the boreal-summer monsoon. The simulations will mainly be carried out on the JUWELS Booster system, which is on number 7 of the Top500 list with the most powerful supercomputers worldwide and on systems operated by our Chinese project partners.
The challenge is to develop the most suitable parallelisation strategy for an architecture, which is based on heterogeneous CPU/GPU processors. The major bottleneck and sometimes the showstopper of high resolution climate simulations is the I/O. In order to achieve high performance with ICON it is essential to enable fast parallel I/O and an optimal MPI (Message Passing Interface) communication when using several thousands of MPI-Processes. Specific libraries for I/O (CDI-PIO) and MPI Communication (YAXT) have been developed at DKRZ for this purpose. Furthermore, post processing of large data sets is a not easy to overcome hurdle.
