Terminates all processes in this communicator. In most systems, this terminates all processes.

Adopts a low-level MPI intercommunicator that was created with any of the low-level MPI facilities. The resulting Intercommunicator object will manage the lifetime of the low-level MPI intercommunicator, and will call MPI_Comm_free(Int32%) when it is disposed or finalized.

Wait until all processes in the communicator have reached the same barrier.

Clones the communicator, creating a new (but distinct) communicator with the same processes. The attributes associated with the communicator are copied to the new communicator; which attributes are copied (and how) is dependent on how the Attributes were created.

Compare two MPI communicators.

Creates a new communicator containing all of the processes in the given group. The resulting communicator may be null, if the calling process is not in this group.

Free the MPI communicator.

Determines whether the specified Object is equal to the current Object.

Finalizer that frees the MPI communicator.

Serves as a hash function for a particular type. GetHashCode()()() is suitable for use in hashing algorithms and data structures like a hash table.

Gets the Type of the current instance.

Determine whether a message from the given source and with the specified tag is available, but don't try to receive the message. This routine will return immediately, regardless of whether a message is available, so it is useful for polling to determine whether any messages need to be handled at this time. If your program can't do any work until a message arrives (and the message is guaranteed to arrive, eventually), use Probe(Int32, Int32) instead.

Creates a shallow copy of the current Object.

Wait for a message from the given source and with the specified tag to become available, but don't try to receive the message. This routine will wait indefinitely for a message meeting the given criteria to arrive, so it should only be invoked when you know a message is coming. If you just want to check whether a message is available use ImmediateProbe(Int32, Int32).

Splits a communicator into several different communicators, each of which is identified by a particular color value.

Returns a String that represents the current Object.

The set of attributes attached to this communicator.

Retrieve the group containing all of the processes in this communicator.

Returns the rank of the currently executing process within this communicator.

Returns the number of processes within this communicator.
