Detailed Description

SerialComm is a simple class that implements the Comm interface for serial communication. Most methods either simply return the parameters passed to them or return a hard coded value.

Author: Jason Cross

Constructor & Destructor Documentation

Jpetra.SerialComm.SerialComm ( )

inline

Creates a new instance of SerialComm.

Member Function Documentation

void Jpetra.SerialComm.barrier ( )

inline

No-op for a serial communicator.

Implements Jpetra.Comm.

int Jpetra.SerialComm.broadcast	(	int	value,
		int	root
	)

inline

Does a broadcast of value to the node itself.

Parameters

value	The int to broadcast to all nodes.
root	The root vnode to gather the ints onto. This is not used for serial communication and is ignored.

Returns: value that was passed in

Implements Jpetra.Comm.

double Jpetra.SerialComm.broadcast	(	double	value,
		int	root
	)

inline

Does a broadcast of value to the node itself.

Parameters

value	The double to broadcast to all nodes.
root	The root vnode to gather the doubles onto. This is not used for serial communication and is ignored.

Returns: value that was passed in

Implements Jpetra.Comm.

Serializable Jpetra.SerialComm.broadcast	(	java.io.Serializable	value,
		int	root
	)

inline

Does a broadcast of value to the node itself.

Parameters

value	The Serializable object to broadcast to all nodes.
root	The root vnode to gather the Serializable objects onto. This is not used for serial communication and is ignored.

Returns: value that was passed in

double [] Jpetra.SerialComm.gatherAll ( double myDouble )

inline

Simply returns an array of size one of myDouble.

Parameters

myDouble the double to gather

Returns: myDouble

Implements Jpetra.Comm.

double [] Jpetra.SerialComm.gatherAll ( double[] myElements )

inline

Simply returns myElements.

Parameters

myElements the double array to gather

Returns: myElements

Implements Jpetra.Comm.

java.io.Serializable [] Jpetra.SerialComm.gatherAll ( java.io.Serializable[] myElements )

inline

Simply returns myElements.

Parameters

inline

Simply returns an array of size one of myInt.

Parameters

myInt the int to gather

Returns: myInt

Implements Jpetra.Comm.

int Jpetra.SerialComm.getNumVnodes ( )

inline

Since this is a serial implementation of comm the value returned will always be 1.

Returns: 1

Implements Jpetra.Comm.

int Jpetra.SerialComm.getVnodeId ( )

inline

Since this is a serial implementation of Comm it always returns 0.

Returns: 0

Implements Jpetra.Comm.

boolean Jpetra.SerialComm.isSerial ( )

inline

Accessor to determine if this is in serial mode. Always returns true.

Returns: true

Implements Jpetra.Comm.

double [] Jpetra.SerialComm.maxAll ( double[] partialMaxs )

inline

Simply returns partialMaxs.

Parameters

partialMaxs the partial maximums

Returns: partialMaxs

Implements Jpetra.Comm.

int [] Jpetra.SerialComm.maxAll ( int[] partialMaxs )

inline

Simply returns partialMaxs.

Parameters

partialMaxs the partial maximums

Returns: partialMaxs

int [] Jpetra.SerialComm.minAll ( int[] partialMins )

inline

Simply returns partialMins.

Parameters

partialMins the partial minimums

Returns: partialMins

Implements Jpetra.Comm.

Serializable Jpetra.SerialComm.minAll ( Serializable partialMins )

inline

Simply returns partialMins.

Parameters

partialMins the partial minimums

Returns: partialMins

Implements Jpetra.Comm.

double [] Jpetra.SerialComm.minAll ( double[] partialMins )

inline

Takes a list of values form all vnodes in the communicator, computes the min, and returns the min to all vnodes.

Parameters

partialMins in on entry; the list of values, usually computed locally, to be summed across all vnodes

Returns: out on exit; the list of values summed across all vnodes

Implements Jpetra.Comm.
