From the computational point of view, the extraction of LCS consists of two main steps: The flowmap computation and the resolution of Finite Time Lyapunov Exponents (FTLE). In this work, we focus on the design, implementation, and parallelization of the FTLE resolution. We offer an in-depth analysis of this procedure, as well as an open source C implementation (UVaFTLE) parallelized using OpenMP directives to attain a fair parallel efficiency in shared-memory environments. We have also implemented CUDA kernels that allow UVaFTLE to leverage as many NVIDIA GPU devices as desired in order to reach the best parallel efficiency. 2023-04-25T01:50:42Z 2023-04-25T01:50:42Z 2023 Book https://link.springer.com/article/10.1007/s11227-022-05017-x https://dlib.phenikaa-uni.edu.vn/handle/PNK/8251 en application/pdf Springer
