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...
This paper focuses on the performance aspects of two types of many-core architectures, Tesla K20c GPU and Xeon Phi 31SP coprocessor, in solving complicated flow structures with a high-order weighted essentially non-oscillatory (WENO) scheme. Some performance optimization techniques are also detailed discussed. The results show that the K20c GPU can run several times faster than Xeon Phi 31SP due to...
