Introduction
The basis for the FINEL2D modelling package is the water flow. Due to the robust explicit Riemann solver almost any application can be calculated. The automatic time step guarantees numeric stability. Drying and flooding of grid cells is treated relative easily within the model.
Parallel computing technique Parallel computing techniques can distribute the FINEL2D computational process over several CPU's. Since the solver uses a explicit time stepping technique most of the computational time is used within 2 loops in the program. These loops are easily parallelised using OpenMP. This free parallelisation software speeds up the program almost lineair. Up to 8 processors can be used simultaineously for one task, which give a speed up of almost a factor 8. Svašek Hydraulics is the owner of state of the art computational facilities. The Svašek cluster of computers consists of the latest multi processor machines and consists of 20 cluster machines (118 cores) with a theoretical peak performance of 1,15 TFLOPS (more than 1 trillion (1012) computations per second). In combination with parallel FINEL2D software many different calculations can be carried out at the same time in a reasonable time schedule. |
