Display: 19 inch LCD; Eight quad-core CPU≥2.5 GHz；; Memory capacity: ≥32GB, and the memory can be expanded to 256GB；; Hard disk capacity is 900G, hard disk type: 3.5-inch hot plug 15000 rpm SAS hard disk, no backup.

Graphics card: 5 12M graphics card; Three Gigabit Ethernet cards; Optical drive: DVD burning; It is suitable for large-scale computational fluid analysis and compatible with fluent software. It is recommended to choose a stable graphics card. If you restart the blue screen because the graphics card is overheated halfway, you will cry to death. If the graphics card is bigger, go to G.

Extended data:

At present, the main bottleneck restricting large-scale parallel operation is the communication between nodes, especially for CFD calculation based on finite element method. In parallel computing, the grid will be divided into many blocks and placed on different computing nodes, so at each iteration step, a lot of data will be exchanged between these nodes, especially in the case of choosing implicit format and coupling algorithm.

Therefore, data communication between nodes is particularly important, and Infiniband is an effective solution at present. Secondly, it is suggested that it is best to install a powerful independent graphics card on at least one node and use this node as the main node.

Although there is no independent graphics card, it will not affect the calculation speed, but it will have a great impact on the fluency of operation. This point was not taken into account when choosing the scheme before, which led to the slow opening of the software, reading data and displaying the model after the machine was installed in place.
