Protected Attributes Ref< MachineTopology >  topology_ int  debug_ Detailed Description The MessageGrp abstract class provides a mechanism for moving data and objects between nodes in a parallel machine. Member Function Documentation virtual void sc::MessageGrp::bcast (  double *    data, int    ndata, int    from = 0 )  [virtual]   Do broadcasts of various types of data. Similar members exist for each of the basic types. int sc::MessageGrp::classdesc_to_index (  const ClassDesc *    )    Each message group maintains an association of ClassDesc with a global index so SavableState information can be sent between nodes without needing to send the classname and look up the ClassDesc with each transfer. These routines return information about that mapping. MessageGrp* sc::MessageGrp::initial_messagegrp (  int &    argc, char **&    argv )  [static]   Create a message group. This routine looks for a -messagegrp argument, then the environmental variable MESSAGEGRP to decide which specialization of MessageGrp would be appropriate. The argument to -messagegrp should be either string for a ParsedKeyVal constructor or a classname. If this returns null, it is up to the programmer to create a MessageGrp. void sc::MessageGrp::initialize (  int    me, int    n )  [protected]   The classdesc_to_index_ and index_to_classdesc_ arrays cannot be initialized by the MessageGrp CTOR, because the MessageGrp specialization has not yet been initialized and communication is not available. CTOR's of specializations of MessageGrp must call the initialize member in their body to complete the initialization process. virtual void sc::MessageGrp::max (  double *    data, int    n, double *    = 0, int    target = -1 )  [virtual]   Global maximization. Similar members exist for each of the basic types. virtual void sc::MessageGrp::min (  double *    data, int    n, double *    = 0, int    target = -1 )  [virtual]   Global minimization. Similar members exist for each of the basic types. virtual void sc::MessageGrp::recv (  int    sender, double *    data, int    ndata )  [virtual]   Receive messages sent sequentually from the sender. Similar members exist for each of the basic types. virtual void sc::MessageGrp::recvt (  int    type, double *    data, int    ndata )  [virtual]   Receive messages sent by type. Similar members exist for each of the basic types. virtual void sc::MessageGrp::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 in sc::MPIMessageGrp. virtual void sc::MessageGrp::send (  int    target, double *    data, int    ndata )  [virtual]   Send messages sequentially to the target processor. Similar members exist for each of the basic types. virtual void sc::MessageGrp::sendt (  int    target, int    type, double *    data, int    ndata )  [virtual]   Send typed messages to the target processor. Similar members exist for each of the basic types. virtual void sc::MessageGrp::sum (  double *    data, int    n, double *    = 0, int    target = -1 )  [virtual]   Global sum reduction. Similar members exist for each of the basic types. The documentation for this class was generated from the following file: message.h
