      abstract     = {Beside the computational scalability of an HPC application,
                      its I/O behaviour can significantly influence the overall
                      performance. This behaviour is influenced by many factors,
                      e.g. by the implementation inside the application, the file
                      system, the network and data hardware and software, as well
                      as, since storage is usually a shared resource, other jobs
                      running on the same cluster. Within EoCoE an I/O
                      benchmarking activity was established to investigate how
                      certain I/O patterns can influence the overall performance
                      and how this behaviour can be reflected within the real
                      world HPC applications to optimize the general I/O
                      bandwidth. The talk will present the benchmarking
                      methodology, common parallel I/O pitfalls, and it should
                      guide HPC application developers in the context of parallel
                      I/O problems.},
