Some Problems in the Simulation of Very Large Hydrodynamic Systems,

摘要

Large scale continuous simulation systems place greater demands on computer resources than most computer applications. The need for extremely large amounts of high speed core and Central Processing Unit time can tax even the largest and fastest machines. In addition, the high cost of each simulation experiment places a great responsibility on the people involved in the design, implementation and use of such systems. This paper describes approaches to dealing with the difficulties inherent to the operation of several simulation programs including both 2-D and 3-D estuary models (used for the study of tidal dynamics and water quality) and global models of ocean and atmospheric circulation. The computer requirements are discussed as well as some of the data management problems. Various procedures for simplifying the use of the programs and for validating and analyzing simulation results are considered, including graphic display. (Author)
