The German Climate Computing Centre (DKRZ) is the central data processing facility for the German climate and Earth system modeling community and is one of the leading facilities in this area. DKRZ operates supercomputers of the highest performance class, modern high-performance clusters and graphics systems as well as one of the largest data and archive systems worldwide.

Our applications department is looking for a

Scientific Programmer (m/f/d) High-Performance Computing

To improve the infrastructure for climate modelling, DKRZ participates in many national and international projects. As part of the national climate modelling initiative PalMod (www.palmod.de) with the aim of a better understanding of climate dynamics during the last glacial cycle, the DKRZ works in the field of software development and model optimization. For this we are looking for further team members.

Your duties:

Together with the colleagues in the PalMod project you work on optimizing the used climate models. The focus here is on increasing the throughput of complex coupled Earth System Models, with which a transient simulation of more than 100,000 years is planned. Key factors in achieving this goal are:

  • Optimal use of SIMD-vectorisation and further hardware specific adaptation for HPC systems
  • Development and implementation of asynchronous execution of model and infrastructure components to increase the parallelism in coupled Earth System Models
  • Improved load-balancing between the individual model components

Your profile:

  • A university degree in Computer Science, Applied Mathematics, Computational Physics/Engineering or related fields
  • Expert programming knowledge (preferably in FORTRAN)
  • Solid knowledge in parallel programming with MPI and OpenMP
  • High experience in use of HPC systems

In addition to the professional aptitude, we expect initiative and willingness to learn. You can expect an exciting project in the field of climate research, interdisciplinary cooperation with other research institutions in Germany, and a challenging task at the interface between HPC and applied science.

The position is advertised subject to the final approval of the funding agency; it is limited to 3 years, with the possibility of extension in the third phase of the PalMod project. The salary will be according to your personal qualification based on the German regulations for the Civil Service (TVöD). Further enquiries can be addressed to Dr. Hendryk Bockelmann ([Email protection active, please enable JavaScript.]).

The call is open until the position is filled. The review of applications will commence on September 1st, 2019. Applicants should submit their informative application containing a letter of motivation, detailed CV, and supporting material, with the reference DKRZ18 to [Email protection active, please enable JavaScript.] or via surface mail to:
