I had the following recommendations from CST, for any body who might need it::smile:
"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., CPU 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 (**broken link removed**) and the MPI Computing Guide (**broken link removed**) to learn more about those special requirements.":wink:
