CST工作站配置求助
要買一個(gè)工作站，主要來跑CST，3萬左右，請(qǐng)各位給點(diǎn)建議，目前的機(jī)器受不了了，謝謝了啊。
做什么類型的仿真？模型大小？什么求解器？要不要用hardware acceleration？這些都不說？
CST FAQ已經(jīng)有介紹：
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.
3萬能買不錯(cuò)的工作站啦，其實(shí)對(duì)CST，就是內(nèi)存越大越好（帶寬也是越大越好～），CPU越快越好（不是越多越好哦～）。
4000多萬的網(wǎng)格，16G內(nèi)存，i7處理器，能夠計(jì)算出來么？
能。
您可以參考一下資料庫(kù)里的一個(gè)White paper，里面有網(wǎng)格與內(nèi)存的簡(jiǎn)單對(duì)應(yīng)關(guān)系，4000萬網(wǎng)格（六面體）加上一些必要的場(chǎng)監(jiān)視器一般也就是5-6G內(nèi)存應(yīng)該足夠。
處理器的話，就是越多越好，越快越好，其個(gè)數(shù)和速度只影響運(yùn)算速度和效率。而內(nèi)存大小的影響，是算、還是不能算的問題。
不過其實(shí)隨著對(duì)工作站構(gòu)架的逐漸了解，我發(fā)現(xiàn)上面的只是大原則，具體的里面的數(shù)據(jù)流啊，線程啊什么的，要達(dá)到最佳配置，還需要更專業(yè)的知識(shí)。
