GeoDict uses the MPI message passing interface protocol to run parallel computations in DiffuDict, ConductoDict, FlowDict, FilterDict-Media, FilterDict-Element, AddiDict, SatuDict and AcoustoDict.

GeoDict’s parallel solvers use the MPI library from Microsoft.

If Microsoft MPI is not already installed, the Microsoft MPI redistributable is installed into C:\Program Files\Microsoft MPI during the installation of GeoDict 2026.
