CST工作站配置求助

做什么类型的仿真?模型大小?什么求解器?要不要用hardware acceleration?这些都不说?
CST FAQ已经有介绍：
Which hardware configuration can be recommended? (Faq #3)
(Last modified: 7/4/2011 )
EM simulations can be classified as high performance computing tasks. Therefore, the CPU, RAM, and graphic performance of workstations used for CST applications should meet high requirements. Likewise, a sufficient power supply and heat flow have to be ensured for the workstation. Thus, we strongly recommend to buy a complete package from a brandname manufacturer, e.g. DELL, HP, or IBM.
We strongly recommend that the chosen hardware meets the following requirements. For a workstation without special acceleration features (i.e., GPU Computing or MPI Computing) we recommend:
■The latest Intel Xeon processor (currently the Intel Xeon processors of the 5600 series, codename “Westmere”)
■Fast RAM memory modules (DDR3, RDIMM). The memory modules need to be arranged in multiples of three (3 modules, 6 modules, etc.) per socket. Please note that the maximum memory bandwidth depends on the number of RAM modules:
    6 modules per socket -> max. bandwidth = 1333 MHz
    9 modules per socket -> max. bandwidth = 800 MHz
    
■Thus, we recommend to prefer a small number of modules with a high capacity rather than a large number of modules with a smaller capacity. For a multiprocessor system we recommend at least 12-24 GB RAM per socket depending on the complexity of your application.
■100% OpenGL compatible graphics card. For the best performance of the 3D modeling and post processing interface we recommend a fast 3D graphics card (e.g. cards of the Nvidia Quadro series).  
If the usage of special acceleration features (GPU Computing/MPI Computing) offered by CST STUDIO SUITE™ is intended there are additional requirements the hardware should meet. Please refer to the GPU Computing Guide (http://updates.cst.com/downloads/GPU_Computing_Guide_2011.pdf) and the MPI Computing Guide (http://updates.cst.com/downloads/MPI_Computing_Guide_2011.pdf) to learn more about those special requirements.
NOTE: CST assumes no liability for any problems caused by this hardware recommendation.

3万能买不错的工作站啦，其实对CST，就是内存越大越好（带宽也是越大越好～），CPU越快越好（不是越多越好哦～）。

4000多万的网格，16G内存，i7处理器，能够计算出来么?

能。
您可以参考一下资料库里的一个White paper，里面有网格与内存的简单对应关系，4000万网格（六面体）加上一些必要的场监视器一般也就是5-6G内存应该足够。
处理器的话，就是越多越好，越快越好，其个数和速度只影响运算速度和效率。而内存大小的影响，是算、还是不能算的问题。
不过其实随着对工作站构架的逐渐了解，我发现上面的只是大原则，具体的里面的数据流啊，线程啊什么的，要达到最佳配置，还需要更专业的知识。
