Message passing in complex irregular systems

MPI is a standard that is well adapted to the needs of the parallel computing community, where performance is a primary concern. However, there is a lack of standards and tools well suited to message passing in complex irregular systems. This paper presents a set of message passing requirements for complex irregular systems. These requirements lead to the implementation of a communication library layered over MPI to provide a higher level of abstraction. The implementation of a training system for the crew of maritime patrol aircraft based on this communication library demonstrates its applicability to solve complex irregular problems
