Distributed Computing

CST MWS features as an option a distributed computing scheme which significantly improves the simulation performance. Sometimes running slight variations of the same model is necessary to reach the simulation goal. The basic idea behind the distributed computing scheme is that these simulations can be performed on various computers in the network. These computers do not require stand-alone CST MWS licenses, but the software has to be installed on each of them. They will be equipped with temporary licenses from the license server for this purpose. If the basic license is node-locked, the license server will be the computer on which the orignal license is installed.

This scheme works on two different levels of complexity. At the lower level, port excitations of a multi-port/ multi-mode structure can be distributed over the network, e.g. to derive the full S-matrix of this component.

In frequency domain the distribution of sample freqeuncy points of an broadband frequency sweep is possible.

At the higher level a parameter study or optimization can be performed. In this case the same structure with different parameter sets is sent to different computers. The results are collected centrally and, if part of an optimization, new parameter sets are created and re-distributed.
