| Abstract: | In this paper,the system speedup ratio,parallel efficiency and scalability was studied by A three dimensional steady- state N- S viscous flow numerical simulation calculation with Fluent liquid calculation software, on Altix450 shared memory server. While comparing the two calculations whose grid numbers are 5million and 10 million respectively, it shows that the system has a more obvious parallel advantage when the grid number is larger. As a conclusion,large shared memory servers are playing an increasingly important role in dealing with numerical simulation in CFD field, and are up to the requirements for high performance calculation in CFD in the future. |
