摘要：
The paper presents the technology of large-scale CFD simulations on supercomputers using finite-volume or finite-difference methods. The study covers various aspects of the numerical experiment and its implementation. The considered problems include the optimal choice of computational domain, minimization of disk space usage, choice of an optimum configuration for a multilevel parallel model, and a method for loading supercomputer nodes. Special attention is paid to the performance problems of multiple access systems taking into account the waiting time in the system queues, the problem of computing reliability, prevention of emergency shutdowns leading to timeconsuming repeated waiting, automatic correction, and optimization of the calculation parameters, etc. Methods are presented for improving the quality of the averaging of the flow fields and the spectral characteristics. © 2016, Pleiades Publishing, Ltd.
