[其它]CST工作站推荐

台式机跑太慢，我这里想买个工作站跑CST，做控制器的CE和RE仿真： aH/ k

Hardware Recommendation Zq|I,l0+E  
t#/YN.@r  
EM simulations can be classified as high performance computing tasks. This means that computers used for CST applications should meet high requirements in terms of CPU, RAM, and graphical performance. Sufficient power supply and cooling also have to be ensured for the workstation. Thus, we strongly recommend buying a complete package from a brandname manufacturer, e.g. DELL, HP, or IBM. a %'the  
u\x}8pn  
We strongly recommend that the chosen hardware meets the following requirements. For a workstation/server without special acceleration features (i.e., GPU Computing or MPI Computing) we recommend: KB,j7 ~V  
Ic:(Gi- %  
◾The latest Intel Xeon processors in a dual socket configuration (currently the Intel Xeon processors of the E5 series, “Ivy Bridge EP”, i.e. Xeon E5-26xx v2). Ovt.!8  
M~#gRAUJ  
◾The fastest RAM memory modules (DDR3, RDIMM). The memory modules need to be arranged in multiples of four (4 modules, 8 modules, etc.) per processor socket for the Xeon E5 platform. Please note that the maximum memory bandwidth depends on the number of RAM modules as well as the type of the modules. The maximum memory bandwidth is currently 1866MHz. A high memory bandwidth is essential to obtain the best possible performance for many of the CST solvers. Please ask your hardware vendor to provide you with a configuration which achieves this memory bandwidth. [f-?ymmT  
fue(UMF~  
◾For a multiprocessor system we recommend at least 32-64 GB RAM per CPU socket depending on the complexity of your application. AGO+p(6d=g  
<#y[gTJ<'>  
◾100% OpenGL compatible graphics card. For the best performance of the 3D modeling and post processing interface we recommend a fast 3D graphics card. The NVIDIA quadro graphics card series is well tested with CST STUDIO SUITE and, thus, we recommend to use a card of this series which is dedicated to CAD/CAE applications. )!Z*.?

The usage of special acceleration features (GPU Computing/MPI Computing) offered by CST STUDIO SUITE introduces additional requirements the hardware should meet. The Supported GPU Hardware Document lists the GPU cards supported for GPU Computing and also contains information about the requirements the host system needs to fulfill. -.@r#d/

If you’re planning a larger hardware investment in high-end HPC hardware like a cluster system, we recommend that you contact us directly so that we can help you during the configuration process. Additionally, we offer benchmarking services in collaboration with the hardware test centers of the vendor of your choice for such high-end systems, to ensure that CST STUDIO SUITE runs fine in the desired hardware and software environment and delivers the performance that you expect. }b"yU#`Q\

Our hardware experts are available to review your desired hardware configuration and provide you with feedback and suggestions to improve the configuration. "3"V3w

CST STUDIO SUITE is available for both Windows and Linux operating system families. To see which operating systems are supported by current and upcoming versions of CST STUDIO SUITE, please see this document. %2/EaaR

Tesla K20英国报价£2873.04，Tesla K40英国报价£4362.48，Quadro K6000英国报价£4140。如果要用Tesla卡，需要再配一块Quadro入门卡（410或者K600）做显示输出。CST的Acceleration token第一年是10000-20000欧元，之后每年15%的maintainance fee。以上按汇率（英镑1:10.45，欧元1:8.5）换算人民币大概就是国内的价钱。 Wo,?+I

工作站能快多少取决于你买的工作站是什么配置。不牵扯GPU的话，把CPU运算能力线性对比一下就知道了。 W*w3[_"sr

一个Tesla K40或者Quadro K6000能加速5倍左右（一个token），两个10倍（两个token），三个14倍，四个17倍（三个token）。 <rSF*

这种高性能计算专业显卡不支持普通台式机，因为主板上PCI-E x16的插槽要多（两条以上），主机功率要够大（750 W以上），主机内存要够多（24-48 GB），需要工作站级别的CPU（Intel Xeon E3以上或者AMD Opteron）。 N)>ID(}F1

接下来直接去咨询CST客服吧。

前段时间公司刚配了一台，主要使用CST和FEKO仿真。比之前的双四核（E5 2643）要快了不少，楼主可以参考一下。 2f:Eof(B

之前看到有一篇文章说对于时域算法优先选主频高的CPU，对于频域算法优选核心数量多的CPU。不知道大家对这个看法有体会吗？
