Abstract

Some features of efficient use of MPI technology for cluster computations of resource demanding problems in hydrodynamics and heat transfer are considered. A short description is given for the SINF package (a parallel 3D Navier-Stokes solver applicable to complex geometry domains with moving boundaries). Using this package, some flows typical for turbomachinery applications are computed (compressor stage, film cooling, vortex-induced vibrations). This work was supported by the Russian Foundation for Basic Research (project № 06-08-01334) and by the Program «Leading Scientific Schools» (project № SH-376.2006.8). The paper was prepared on the basis of the author’s report at the International Conference on Parallel Computing Technologies (PaVT-2007; http://agora.guru.ru/pavt2007).
