#include <cparsimcomm.h>
Inheritance diagram for cParsimCommunications:
It provides an abstraction layer above MPI, PVM, shared-memory communications, etc.
This is an interface: functionality is added by specific subclasses for MPI, PVM, etc.

|
Virtual destructor.
|
|
Broadcasts packed data with given tag to all partitions. This default implementation just simply sends the data to every other partition. |
|
Creates an empty buffer that can be used to send/receive data.
|
|
Returns total number of partitions.
|
|
Returns id of this partition, an integer in the range 0. |
|
Init the library -- parameters (if there are any) should have been passed in constructor. This process may also include starting the program on all processors needed for the current simulation run, if it is not handled by the parallel runtime system (e.g. MPI handles it via mpirun). |
|
Receives packed data with given tag from given destination. Normally returns true; false is returned if blocking was interrupted by the user. |
|
Receives packed data with given tag from given destination. Call is non-blocking -- it returns true if something has been received, false otherwise. |
|
Recycle communication buffer after use. May be used to implement pooling, etc. |
|
Sends packed data with given tag to destination.
|
|
Shutdown the communications library.
