(Course no. tba in the training programme 2026 of Forschungszentrum Jülich)
The course will take place in October, exact days TBA.
This course will take place as an online event. The link to the streaming platform will be provided to the accepted registrants only. The course will be held in English.
Course Content:
The focus of this course is on the concept of performing I/O operations (reading/writing from/to file) in parallel, as well as demonstrating the usage of common libraries to perform such parallel I/O tasks. This course will start with an introduction of different parallel I/O strategies. It will then cover the NetCDF-4 and HDF5 libraries. Lastly, optimisation potential and best practices for parallel I/O are discussed.
The three half-day course consist of lectures as well as practical exercises on implementing the techniques presented in the course.
Note: This is an introductory course into an advanced topic. Familiarity with HPC and parallel programming are prerequisite.
