| Summary: | <p>This paper presents the message passing interface (MPI)-based parallelization of the three-dimensional hydrodynamic model SHYFEM (System of HydrodYnamic Finite Element
Modules). The original sequential version of the code was parallelized in order to reduce the execution time of high-resolution configurations using
state-of-the-art high-performance computing (HPC) systems. A distributed memory approach was used, based on the MPI. Optimized numerical libraries
were used to partition the unstructured grid (with a focus on load balancing) and to solve the sparse linear system of equations in parallel in the
case of semi-to-fully implicit time stepping. The parallel implementation of the model was validated by comparing the outputs with those obtained
from the sequential version. The performance assessment demonstrates a good level of scalability with a realistic configuration used as benchmark.</p> |
