VANT. Ser.: Mat. Mod. Fiz. Proc 2021. Вып.4. С. 76-82.

Method of finite volumes on unstructured meshes is used for discretization of Navier-Stocks equation within "Logos-AeroHydro" module of "Logos" software package. It results into solution of SLAE with a small-block matrix to find several interdependent indeterminates in each cell of the mesh. During parallelization of computing algorithms to solve SLAE, SSE2-SSE4.2 (Intel®LegacySSE), Intel®AVX, Intel®AVX512 techniques are used. IAL libraries developed in RFNC-VNIIEF are described; the issues related to creation of optimized libraries are discussed. Implementation results for IAL libraries for vector optimization of "Logos-AeroHydro" module are provided.

Keywords: vector optimization, SSE, AVX, "Logos" software package.
