New cooperative parallel strategy for massive CFD computations of aerodynamic data on multiprocessors

摘要

A new parallel cooperative strategy for iterative multiparametric numerical processes is proposed. The idea of the proposed technology consists in employing the information exchange between the members of the same parametric family. With this end in view, the information on already computed (or partially computed) solutions is distributed in the multilevel way which results in an essential speed-up of the whole parallel process. Based on this general approach, a new efficient strategy of parallel cooperative CFD computations is implemented which allows the practical construction of large-size aerodynamic data-bases by means of high-accuracy Navier-Stokes simulations. The results show that the proposed technology essentially reduces CPU time needed for large-scale aerodynamic computations.
