NLSEmagic: Nonlinear Schrödinger Equation Multidimensional
Matlab-based GPU-accelerated Integrators using Compact high-order schemes
|
|
NLSEmagic is a package of C and MATLAB script codes which
simulate the nonlinear Schrödinger equation in one, two, and three dimensions.
The code includes MEX integrators in C, as well as NVIDIA CUDA-enabled GPU-accelerated
MEX files in C. The MATLAB script files call the compiled MEX codes forming an
easy-to-use highly efficient program. The codes utilize a fourth-order (in time)
Runge-Kutta scheme combined with the choice of standard second-order (in space) finite
differencing, or a compact two-step fourth-order (in space) finite differencing.
The code was developed as part of my Ph.D. dissertation, and includes two versions. One is a streamlined easy-to-follow script code which is meant as an example of how to use the MEX codes, while the other version is a full-research code which can reproduce my research results. NLSEmagic is freely distributed for use and modification. However, a nominal donation and acknowledgment of authorship is appreciated. |
