Detailed Description

Parallel simulation support has a layered architecture, with the following layers:

  1. Communications layer, represented by cParsimCommunications. This encapsulates all details of message passing between parts of a program that executes in parallel, and hides details of the communications library (MPI, PVM, ...). Subclasses implemented here are cMPICommunications, cNamedPipeCommunications, cFileCommunications.
  2. Partition layer, represented by cParsimPartition. This encapsulates the task of distributing the simulation model over several partitions, and handles messaging between these partitions. It relies on layer 1 for this.
  3. Synchronization layer, represented by cParsimSynchronizer. It encapsulates the different parallel simulation algorithms like the conservative null message algorithm. This layer heavily cooperates with the message scheduler of the simulation.
