Job Offer: Parallel Programming Environments and Libraries

Leibniz Supercomputing Centre (Leibniz-Rechenzentrum, LRZ) of the Bavarian Academy of Sciences and Humanities is the IT Service Provider for all Munich universities as well as a growing number of research organisations throughout Bavaria. In addition to this regional focus, LRZ also plays an important role as a member of GCS (Gauss Centre for Supercomputing), delivering top-tier HPC services on the national and European level. We support ground-breaking research and education throughout a wide range of scientific disciplines by offering highly available, secure and energy-efficient services based on cutting-edge IT technology.

We are currently looking for an

Expert for Parallel Programming Environments and Libraries

Role and Responsibilities:

  • Installation, correctness testing and performance verification of communication and message passing libraries (MPI, GPI, Global Arrays, OpenShmem, OpenCoarrays etc.) on HPC systems
  • Establishing tools, workflows and a test suite for analysing, isolating and classifying performance and correctness issues in the communication/transport layers of abovementioned libraries
  • Perform research in the area of programming model innovations (e.g., fault tolerance)
  • Develop containerized solutions for scientific and application driven workloads.
  • Processing and tracking of identified software bugs
  • Assure the proper integration of the communication libraries with the scheduling systems
  • Assure parallel environment service quality (especially after system maintenance measures)
  • Maintain and extend the user documentation for setting up optimally performing application runs


  • Candidate should have in-depth knowledge of at least one HPC language (C, C++, Fortran) and baseline knowledge of all of them. 
  • Experience with UNIX/Linux and the development environment used there (compilers, scripting languages, make, autoconf etc.) is required
  • General knowledge of parallel programming is required; in-depth knowledge about the message-passing interface (MPI) would be ideal.
  • Knowledge about tools typically used for performance and correctness checking would be good.

We offer a multifaceted and intellectually stimulating position with flexible working hours and a family-friendly atmosphere in one of the largest and most innovative scientific data centres in Europe. You will work in a dynamic, collaborative and innovative environment characterised by an excellent working atmosphere and creative leeway. If you are interested and a topic matching your work theme can be identified, a subsequent doctoral graduation is possible. Salary and benefits are compensated according to the collective employment agreement of the German Federal States (Tarifvertrag der Länder, TV-L). Classification is based upon qualifications and assigned duties. LRZ operates flexible work schemes. Handicapped persons will be given preference to other equally qualified applicants.
