BCP_message_tag
This enumerative constant describes the message tags different processes of BCP understand.
virtual void send(const int target, const BCP_message_tag tag)=0
Send an empty message (message tag only) to the process given by the frist argument.
virtual bool start_processes(const BCP_string &exe, const int proc_num, const bool debug, int *ids)=0
Spawn proc_num processes, all with the same executable.
virtual int num_procs()
Return the number of processes.
virtual void receive(const int source, const BCP_message_tag tag, BCP_buffer &buf, const double timeout)=0
Blocking receive with timeout.
This is an abstract base class that describes the message passing environment.
This class is a very simple impelementation of a constant length string.
This class is an abstract base class for the initializer class the user has to provide.
virtual bool probe(const int source, const BCP_message_tag tag)=0
Probe if there are any messages from the given process with the given message tag.
virtual int start_process(const BCP_string &exe, const bool debug)=0
Spawn a new process.
This class describes the message buffer used for all processes of BCP.
virtual ~BCP_message_environment()
Being virtual, the destructor invokes the destructor for the real type of the object being deleted...

virtual int register_process(USER_initialize *user_init)=0
A process can register (receive its process id) with the message passing environment.
virtual bool alive(const int pid)=0
Test if the process given by the argument is alive or not.
virtual void multicast(int num, const int *targets, const BCP_message_tag tag)=0
Send an empty message (message tag only) to all the processes in the process array.
