Prerequisites

Familiarity with Linux and Linux editors is recommended. Programming experience in Fortran or C, some knowledge about parallel programming.

Furthermore, we require that you bring your application including a test case that adheres to the following guideline:

• • number of cores:
    • In order to be representative, the test case should be in size comparable to your current and maybe future production runs.
    • In order to save valuable resources, it should however be as small as possible.
    • So take into account to reduce the size of your test case as long as the profile stays almost constant. This can often be achieved by reducing the simulated domain and keeping the computational load per core constant ("weak down scaling").
  •  wall time:
    • In order to allow for a productive as well as effective workflow, the wall time should be a few minutes only.
    • At the same time, it should cover all important parts of the code, including I/O.
    • So take into account to reduce the number of simulated time steps.

PRACE PATC and bwHPC-C5

HLRS is part of the Gauss Centre for Supercomputing (GCS), which is one of the six PRACE Advanced Training Centres (PATCs) that started in Feb. 2012. The mandate for the PATCs is as follows: "The PRACE Advanced Training Centres will serve as European hubs of advanced, world-class training for researchers working in the computational sciences." (see D3.2.3)
This course is a PATC course, see also the PRACE Training Portal and Events. For participants from public research institutions in PRACE countries, the course fee is sponsored for this part of the course through the PRACE PATC program. For details, see the section about the course fee above.

HLRS is also member of the Baden-Württemberg initiative bwHPC-C5.
This course is also provided within the framework of the bwHPC-C5 user Support.
