CST Studio Suite Recommended Hardware

EM simulations can be classified as high performance computing tasks. This means that computers used for CST applications must meet high requirements in terms of CPU, RAM, and graphical specifications in order to achieve optimal performance. Sufficient power supply and cooling must also be ensured for the workstation or server. We strongly recommend buying a complete package from a brand-name manufacturer, e.g. DELL, HP, or IBM, and that the chosen hardware meets the following requirement

Processor
Minimum requirement: Intel x86-64 processor
High end server/workstation recommendation: Dual 2nd Generation Intel Xeon Scalable Processors (also known as „Cascade Lake“)
Notes for recommended hardware: We recommend high processor base clock frequency (>3 GHz) and 8-10 cores per CPU are recommended for general-purpose simulation workstation
Memory (RAM)
Minimum requirement: 16 GB
High end server/workstation recommendation: 32–64 GB per CPU
Notes for recommended hardware: We recommend fastest RAM memory modules available, currently DDR4-2933.
Graphics card
Minimum requirement: 100% OpenGL compatible graphics card
High end server/workstation recommendation: NVIDIA Quadro series card dedicated to CAD/CAE applications
Notes for recommended hardware:
Storage
Minimum requirement: 30 GB of free disk space
High end server/workstation recommendation: At least 500 GB hard disk drive
Notes for recommended hardware: SSDs may be used, but are not necessary for good simulation performance
GPU computing (optional)
Minimum requirement: Supported GPU card
High end server/workstation recommendation: High-end NVIDIA Quadro or Tesla card
Notes for recommended hardware: Please refer to the GPU computing guide
MPI computing (optional)
Minimum requirement: Dedicated compute cluster hardware
High end server/workstation recommendation:
Notes for recommended hardware: Fast network interconnects with low latency, e.g. Infiniband or Intel OmniPath, are strongly recommended. Please refer to the MPI computing guide
Distributed computing (optional)
For optimal simulation performance, the solver servers should run on separate computers from the frontend and the main controller. A fast network connection between the solvers servers, the main controller, and the frontend is recommended as simulations may generate a lot of data that needs to be transferred.
