GPU RKF45 (Runge–Kutta–Fehlberg) ODE parallel solver written in pycuda

The Runge–Kutta–Fehlberg method (RKF45) is one of the widely used ODE solvers. GRKF45 is a parallel RKF45 solver with many different parameter sets.

The original RKF45 code was taken from cpp code by John Burkardt (LGPL).

Currently, you need to define the ODEs in r4_f0, r4_f1, r4_f2, .... in GRKF45.

codes

  • grkf45_1d (1D ODE)
  • grkf45_2d (2D ODE, the van der pol oscillator)

  • grkf45_3d (3D ODE, the Lorenz attractor)
