CSG Parallelism and Performance

A cooperation of TU Darmstadt
and RWTH Aachen University

Cross-Sectional Group

The CSG Parallelism and Performance supports performance engineering, in particular performance management, modeling, optimization, and parallel programming.

In the foreseeable future, the HPC community is approaching a new era of supercomputing known as exascale, which stands for the ability to execute 1018 floating operations per second. To reach exascale, the design of supercomputers becomes more and more complex and, hence, does the programming. For instance, hardware architectures are increasingly heterogeneous, forcing HPC applications to exploit different levels of parallelism. Ensuring both correctness and performance of applications running on such systems is a non-trivial task, requiring substantial expertise in HPC.

In the CSG Parallelism and Performance, HPC experts from RWTH Aachen University and TU Darmstadt, with Jülich Supercomputing Centre as an associated partner, bundle their expertise to foster the efficient and productive use of HPC current as well as emerging infrastructures by users from a broad spectrum of scientific disciplines. To achieve this goal, we provide user support, offer training, and organize workshops, targeting novice as well as advanced HPC users. In addition, we conduct research related to our service portfolio and, in particular, develop suitable tools.
