Detailed Description

template<class Type>
class CommCollective< Type >

is a template wrapper around MPI functions for collective communicatios

This class is specialized for collective communications and functions

Constructor & Destructor Documentation

CommCollective() [1/2]

template<class Type >

CommCollective< Type >::CommCollective	(	void *	buf,
		uint	size,
		uint	root
	)

constructor

Parameters

root	another constructor for Communicator class

CommCollective() [2/2]

template<class Type >

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

constructor specialized for root=comsize-1

Parameters

size	another constructor for Communicator class, this one sets the root as comsize-1 for hdf5

Member Function Documentation

bcast()

template<class Type >

void CommCollective< Type >::bcast

(

)

blockin broadcast

getTotalNumber() [1/2]

template<class Type >

void CommCollective< Type >::getTotalNumber	(	uint *	offset,
		uint *	myvalue,
		uint *	totalvalue
	)

calculates the world population for a given variable

getTotalNumber() [2/2]

template<>

void CommCollective< uint >::getTotalNumber	(	uint *	offset,
		uint *	myvalue,
		uint *	totalvalue
	)

< the largest offset belongs to the processor with highest rank, add this to its number of cubes will give us the total value

Ibcast()

template<class Type >

void CommCollective< Type >::Ibcast

(

)

non-blocking broadcast

I spoecialized this function since this is only needed for unsigned ints

IgetTotalNumber() [1/2]

template<class Type >

void CommCollective< Type >::IgetTotalNumber	(	uint *	offset,
		uint *	myvalue,
		uint *	totalvalue
	)

calculates the world population for a given variable in a non-blocking fashion

IgetTotalNumber() [2/2]

template<>

void CommCollective< uint >::IgetTotalNumber	(	uint *	offset,
		uint *	myvalue,
		uint *	totalvalue
	)

< the largest offset belongs to the processor with highest rank, add this to its number of cubes will give us the total value

waitOnRequest()

template<class Type >

void CommCollective< Type >::waitOnRequest
