Constructor & Destructor Documentation sc::MPIMessageGrp::MPIMessageGrp (  MPI_Comm    comm )    Use an MPI communicator to create a MessageGrp. The comm argument could be a subset of MPI_COMM_WORLD, for example. sc::MPIMessageGrp::MPIMessageGrp (  int *    argc, char ***    argv )    Use argc and argv to create a MPIMessageGrp. This would have to be used for implementations of MPI that have MPI_Init fill in argc and argv. Member Function Documentation void sc::MPIMessageGrp::reduce (  double *   , int    n, GrpReduce< double > &   , double *    scratch = 0, int    target = -1 )  [virtual]   Global generic reduction. Similar members exist for each of the basic types. Reimplemented from sc::MessageGrp. The documentation for this class was generated from the following file: messmpi.h
