Copy constructor. |
Instances of the MpiComm class provide information about MPI communicators. In addition to the functionality of the base class Communicator, they also provide a "real" MPI communicator handle resembling the one used in the target application.
pearl::MpiComm::MpiComm | ( | IdType | id, |
const String & | name, | ||
const MpiGroup & | group, | ||
MpiComm * | parent | ||
) |
Creates a new MPI communicator definition instance and initializes it with the given values.
id | Global communicator identifier |
name | Communicator name |
group | Associated process group object |
parent | Parent communicator (NULL for root communicators or when this information is not available) |
virtual pearl::MpiComm::~MpiComm | ( | ) | [virtual] |
Releases all allocated resources and destroys the instance.
pearl::MpiComm::MpiComm | ( | const MpiComm & | comm | ) | [protected] |
Copies the given instance and duplicates the associated MPI communicator handle using MPI_Comm_dup. It is 'protected' to prevent accidental invocation; users need to call MpiComm::duplicate() explicitly to create a communicator copy.
comm | MPI communicator definition to duplicate |
MpiComm* pearl::MpiComm::duplicate | ( | ) | const |
MPI_Comm pearl::MpiComm::getComm | ( | ) | const |
Returns the MPI communicator handle associated with this communicator object.
