Benchmarks
The developments of the exaFOAM project are showcased by Grand Challenges and Industrial Applications. These cases are designed to push available HPC systems to their limits and showcase the performance gains achieved over the duration of the project. For the continuous assessment of the software components during software development, microbenchmarks have been derived from the Grand Challenges and Industrial Applications.
At least one microbenchmark has been derived from each application, which captured and highlighted their computational bottlenecks at lower computational cost.
You find the list of the available test cases and the links for the source codes in the tables below.
For some of the benchmarks grid and restart files are available in the DaRUS data repository of the University of Stuttgart.
