　　In this talk, a fast GPU implementation of stable Runge-Kutta integration factor methods is presented for three dimensional parabolic equations.The method combines fast GPU implementation of discrete Sine/Fourier transform with fast matrix multiplication operations.The new method can efficiently solve three dimensional parabolic equations with stiff nonlinearity.Numerical experiments demonstrate effectiveness of the new method for both linear and nonlinear model problems.
