Detailed Description

Description of a cluster and the nodes in it.

This class holds the basic description of a cluster. It defines which nodes are part of the cluster and which file systems each node has access to. If a data set is distributed over many file systems, the cluster description tells which node can handle a data set part on a particular file system.

Currently the information is made persistent in a LOFAR .parset file. In the future it needs to use the Centrol Processor Resource Manager.

Constructor & Destructor Documentation

ClusterDesc() [1/2]

dp3::common::ClusterDesc::ClusterDesc ( )

inline

Construct an empty object.

ClusterDesc() [2/2]

dp3::common::ClusterDesc::ClusterDesc ( const std::string &  parsetName )

explicit

Construct from the given parameterset.

Member Function Documentation

addNode()

void dp3::common::ClusterDesc::addNode	(	const NodeDesc &	node,
		bool	canExist = false
	)

Add a node description. A node with an already existing name is not added. If canExist=false, an exception is thrown if existing.

getMap()

const std::map<std::string, std::vector<int> >& dp3::common::ClusterDesc::getMap ( ) const

inline

Get the map of file system to node index.

getName()

const std::string& dp3::common::ClusterDesc::getName ( ) const

inline

Get the cluster name.

getNode()

const NodeDesc& dp3::common::ClusterDesc::getNode

(

const std::string &

nodeName

)

const

Get a specific node. An exception is thrown if not found.

getNodes()

const std::vector<NodeDesc>& dp3::common::ClusterDesc::getNodes ( ) const

inline

Get all nodes.

setName()

void dp3::common::ClusterDesc::setName ( const std::string &  name )

inline

Set cluster name.

write()

void dp3::common::ClusterDesc::write

(

std::ostream &

os

)

const

Write it in parset format.
