Fig. 10From: Accelerating CFD simulation with high order finite difference method on curvilinear coordinates for modern GPU clustersComparison of WENO interpolations. In original WENO interpolation, the characteristic space is built at i+1/2, and \(u^{\pm }_{i+1/2}\) are computed simultaneously in a loop. In modified WENO interpolation, the characteristic space is built at i, and \(u^{-}_{i+1/2}\) and \(u^{+}_{i-1/2}\) are computed simultaneously in a loop. In modified WENO interpolation, point stencils are the same, so the characteristic variables and smoothness indicators are shared, thus it reduces calculation and global memory accessBack to article page
