The dynamic simulator of the compressor station on 6 gas compressors, which is the basis of the demo database, requires significant resources, that is a processor with frequency of more than 1 GHz (x86) and memory up to 200 MB. These computing resources are needed directly for the dynamic simulator and are not a general indicator of the program's resource intensity in the final tasks! Memory requirements, on the contrary, are a typical indicator for a similar graphical AWP station.
