In this paper the Graphic Processing Unit (GPU) is applied in order to improve the computational performance of process systems optimal control calculations. To apply GPU massive parallel architecture, a simplified version of interior point optimisation algorithm was selected and modified to fulfil special hardware requirements of GPU architecture. In this algorithm, a damped nonlinear Newton with preconditioned iterative linear solver was used to solve Dual-Primal equations. The comparison of results between this implementation and standard CPU-based implementation shows considerable improvement in computational performance.
