Private Member Functions
void	init ()
Private Attributes
int	numChunks
	Number of chunks in which the cache is splitted.
int	finishedChunks
	Number of chunks that have already been completely acknowledged.
CkCacheArrayCounter	localChares
	A list of all the elements that are present in the local processor for the current iteration.
CkCacheArrayCounter	localCharesWB
	A list of all the elements that are present in the local processor for the current iteration with respect to writeback.
int	syncdChares
	number of chares that have checked in for the next iteration
int	numLocMgr
	The number of arrays this Manager serves without support for writeback.
CkGroupID *	locMgr
	The group ids of the location managers of the arrays this Manager serves with support for writeback.
int	numLocMgrWB
	The number of arrays this Manager serves with support for writeback.
CkGroupID *	locMgrWB
	The group ids of the location managers of the arrays this Manager serves with support for writeback.
CmiUInt8	dataArrived
	particles arrived from remote processors, this counts only the entries in the cache
CmiUInt8	dataTotalArrived
	particles arrived from remote processors, this counts the real number of particles arrived
CmiUInt8	dataMisses
	particles missed while walking the tree for computation
CmiUInt8	dataLocal
	particles that have been imported from local TreePieces
CmiUInt8	dataError
	particles arrived which were never requested, basically errors
CmiUInt8	totalDataRequested
	counts the total number of particles requested by all the chares on the processor
CmiUInt8	maxData
	maximum number of nodes stored at some point in the cache
CmiUInt8 *	chunkWeight
	weights of the chunks in which the tree is divided, the cache will update the chunk division based on these values
CmiUInt8	maxSize
	Maximum number of allowed data stored.
int *	chunkAck
	number of acknowledgements awaited before deleting the chunk
int *	chunkAckWB
	number of acknowledgements awaited before writing back the chunk
std::map< CkCacheKey, CkCacheEntry * > *	cacheTable
	hash table containing all the entries currently in the cache
int	storedData
std::map< CkCacheKey, int >	outStandingRequests
	list of all the outstanding requests.
