HPC Application Optimisation Engineer (all genders)

To improve the infrastructure for climate modelling, DKRZ participates in many national and international projects. Through its research group on Scientific Computing, DKRZ is linked to the Department of Informatics at the University of Hamburg.

In 2020, the current High-Performance Computing (HPC) system 'Mistral' will be replaced by a new system. This involves implementation of a new HPC user environment, preparing the transition from the old to the new system, evaluate users’ needs before the system is handed over, and finally support the users while actually relocating their applications.

Your role

As part of the HPC application support team, you will actively contribute to designing the user experience for the next HPC system. In close cooperation with the first/second level support, the system administrators, and the power users, you will contribute to the operational services in two main areas: i/ job-based performance monitoring and ii/ HPC-tools related to performance analysis of user applications. Furthermore, front-line support for the High  Performance Computing user community will complete this position.

Your responsibilities

  • Develop, implement and run a performance monitoring environment for Slurm batch jobs
  • Proactive approach to customer service regarding the optimisation of user code on the new HPC system and analysing user needs
  • User support and training for HPC tools (debugger, profiler, tracing tools)
  • Develop and run continuous diagnostic tests of the HPC system to isolate issues and identify potential for optimisation and enhancements
  • Collaborate  and  consult  with  the  system  administrators,  scientists,  and  researchers  to resolve technical issues

Your profile

  • Expert   knowledge   in   HPC   environments   -   parallelisation,   compiling,   and   analysing applications on Linux clusters
  • Ideally knowledge in monitoring, profiling and tracing tools for HPC systems and applications

Basic Qualifications

  • Minimum Bachelor’s degree, ideally Master’s degree in Computer Science, or equivalent degree, preferably with emphasis on High-Performance Computing
  • Strong familiarity with the Linux command line, HPC related programming languages (C/C++, FORTRAN, Python), and parallelisation approaches (especially MPI)
  • Excellent communication skills; ability to work and communicate effectively with people at all levels of the organization

We offer an interesting, diversified and challenging work in a flexible academic environment. Follow your own initiative, build strong collaborations within DKRZ and with scientific partners, and shape future services and research directions in a field of high relevance to society. We expect capacity for teamwork in an interdisciplinary environment and willingness to travel nationally and internationally. We also offer opportunities for further qualification in the field of High-Performance Computing.

The position will start in August 2020 the earliest. The contract is initially limited for 2 years. Payment will be in accordance with the German public service positions (TVöD according to the applicant's qualifications), including extensive social security plans. The conditions of employment follow those of the German civil service.
