Abstract :
In the last few years lots of industrial simulation applications were ported onto parallel systems to gain more computational power. Besides other parallelisation techniques message-passing seems to be the most powerful and accepted one. Since MPI is the upcoming standard definition for message-passing libraries, portability and adaptation among different hardware- and software-environments becomes more and more realistic. However some problems are still unsolved, if two or more independent parallel MPI-applications are coupled and work together. This article shows some of the problems which might arise in coupling independent parallel codes: e.g. management of separate address spaces, definition of dedicated neighborhoods, integration of dynamic process sets and synchronisation events
