چکیده

In the paper we discuss the main features of the software package for numerical simulations of the surface water dynamics. We consider an approximation of the shallow water equations together with the parallel technologies for NVIDIA CUDA graphics processors. The numerical hydrodynamic code is based on the combined LagrangianEuler method (CSPH-TVD). We focused on the features of the parallel implementation of Tesla line of graphics processors: C2070, K20, K40, K80. By using hierarchical grid systems at different spatial scales we increase the efficiency of the computing resources usage and speed up our simulations of a various flooding problems.

Curve-Fitting on Graphics Processors Using Particle Swarm Optimization

Curve fitting is a fundamental task in many research fields. In this paper we present results demonstrating the fitting of 2D images using CUDA (compute unified device architecture) on NVIDIA graphics processors via particle swarm optimization (PSO). Particle swarm optimization is particularly well-suited to implementation on graphics processors using CUDA as each CUDA thread can be made to mod...

The Dslash operator is used in Lattice Quantum Chromodymamics (LQCD) applications to implement a Wilson-Dirac sparse matrix-vector product. Typically the Dslash operation has been implemented as a parallel program. Today’s Graphics Processing Units (GPU) are designed to do highly parallel numerical calculations for 3D graphics rendering. This design works well with scientific applications such ...

MPI- and CUDA- implementations of modal finite difference method for P-SV wave propagation modeling

Among different discretization approaches, Finite Difference Method (FDM) is widely used for acoustic and elastic full-wave form modeling. An inevitable deficit of the technique, however, is its sever requirement to computational resources. A promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

Programming CUDA-Based GPUs to Simulate Two-Layer Shallow Water Flows

The two-layer shallow water system is used as the numerical model to simulate several phenomena related to geophysical flows such as the steady exchange of two different water flows, as occurs in the Strait of Gibraltar, or the tsunamis generated by underwater landslides. The numerical solution of this model for realistic domains imposes great demands of computing power and modern Graphics Proc...

Porting NAHUJ to CUDA

This white-paper reports on an enabling effort that involves porting a legacy 2D fluid dynamics Fortran code to NVIDIA GPUs. Given the complexity of both code and underlying (custom) numerical method, the natural choice was to use NVIDIA CUDA C to achieve the best possible performance. We achieved over 4.5x speed-up on a single K20 compared to the original code executed on a dual-socket E5-2687W.
