This paper studies the implementation and optimization of a high-order weighted essentially non-oscillatory (WENO) solver to the solution of the Euler equations on the multi-core and many-core architectures (Intel Ivy Bridge CPU, Intel Xeon Phi 7110P coprocessor and NVIDIA Kepler K20c GPU). The implementation of up to ninth-order accurate WENO schemes is used in the solver. For the GPU platform, both...
Finite-time Lyapunov exponent (FTLE) is widely used to extract coherent structure of unsteady flow. However, the calculation of FTLE can be highly time-consuming, which greatly limits the application's performance efficiency. In this paper, we accelerate a double precision PDE-based FTLE application for two- and three-dimensional analytical flow field on Intel multi-core and many-core architectures...
