	Abstract base class for DataStack types. More...
struct	HMP::LoadManager::DataStack< StackT >
	Concrete derivation of DataStackBase, managing an array of fundamental data types (or tuples thereof, if DataStackBase::typeMultiplicity is greater than one). More...
struct	HMP::LoadManager::Chunk
	Definition of a small chunk of work. Used to communicate workload between different LoadManager instances. More...
class	HMP::LoadManagerMaster
	LoadManager master implementation, which is responsible for distributing work and synchronizing data. More...

newLoadManager()

LoadManager* HMP::newLoadManager ( const int  serverRank = 0, const MPI_Comm  communicator = MPI_COMM_WORLD  )

inline

Create a new LoadManager instance. If the current MPI rank is the designated master rank, returns a LoadManagerMaster instance, otherwise returns a LoadManagerSlave instance.

Parameters

serverRank	MPI rank to assume the master role.
communicator	The MPI communicator to operate on.

Returns

LoadManager* Newly generated LoadManager instance.
