OpenCL parallel integration of Ordinary Differential Equations
We provide a complete example that performs a integration of the Hénon-Heiles Hamiltonian using two different integrator schemes.
In order to run this software you need to have the OpenCL libraries and headers installed in your system (Intel, AMD, NVIDIA and Apple vendors have been successfully tested).
- OpenCL parallel integrator based on Runge-Kutta. Check the provided README for compilation instructions. You can modify some parameters by looking at the include files as explained in the README.
- OpenCL parallel integrator based on Taylor Series Method (TIDES). Check the provided README for compilation instructions. You can modify some parameters by looking at the include files as explained in the README.
We show a movie of the FLI chaos indicator of the Hénon-Heiles system. The orbits have been integrated using the Taylor Series Method with a tolerance of 1E-8 in the interval [0, 1000]. The movie consists of 100 frames with a resolution of 512x512, and the total time to generate it with a Tesla C2075 is about 50 minutes.
