Detailed Description

template<class Type>
class CommPoint2Point< Type >

A template wrapper around MPI functions for point to point communication.

class CommPoint2Point abstracts point to point communications and functions

Constructor & Destructor Documentation

CommPoint2Point() [1/3]

template<class Type >

CommPoint2Point< Type >::CommPoint2Point	(	void *	buff,
		uint	size,
		uint *	tg,
		uint	snd,
		uint	rcv,
		uint	type,
		MPI_Comm	Comm
	)

full constructor

< default tag for message send and recieve is "0", MPI_ANY_TAG is onlu OK for recieve commnad so it can not be used here

Parameters

Comm	If communicator is not specified it will be set as MPI_COMM_WORLD by default

CommPoint2Point() [2/3]

template<class Type >

CommPoint2Point< Type >::CommPoint2Point	(	void *	buff,
		uint	size,
		uint	snd,
		uint	rcv
	)

default constructor

Parameters

rcv	another constructor for Communicator class

CommPoint2Point() [3/3]

template<class Type >

CommPoint2Point< Type >::CommPoint2Point	(	void *	buff,
		uint	size
	)

deferring the assigment of sender and reciever

Parameters

size	another constructor for Communicator class, deferes assigning sender and reciever

~CommPoint2Point()

Member Function Documentation

assignReciever()

template<class Type >

void CommPoint2Point< Type >::assignReciever

(

uint

rcv

)

assigns the sender of the message

assignSender()

template<class Type >

void CommPoint2Point< Type >::assignSender

(

uint

sndr

)

getOffset()

template<class Type >

void CommPoint2Point< Type >::getOffset	(	uint	myvalue,
		uint *	offset
	)

calculates the offset of each processor for variable myvalue

Parameters

offset

gets the number of elements before the current processor, it is needed for globally defining the elements

Irecv()

template<class Type >

void CommPoint2Point< Type >::Irecv

(

)

non-blocking recieve

Isend()

template<class Type >

void CommPoint2Point< Type >::Isend

(

)

non-blocking send

myRank()

template<class Type >

int CommPoint2Point< Type >::myRank

(

)

assigns the destination the message gets the ranl of the processor

mySize()

(

)

recv()

template<class Type >

void CommPoint2Point< Type >::recv

(

)

blocking recieve

send()

template<class Type >

void CommPoint2Point< Type >::send

(

)

blocking send
