Detailed Description

Class ProcessorMapping represents the processor assignments of patches to processors. It makes sure that all processor assignments are in the range from 0 through NODES-1 and answers whether a particular assignment is local to the processor.

Constructor & Destructor Documentation

SAMRAI::hier::ProcessorMapping::ProcessorMapping (   )

Create a default processor mapping array with 0 elements. Before the mapping can be used, its size should be set using the function setMappingSize() and each element of the mapping should be set by setProcessorAssignment().

SAMRAI::hier::ProcessorMapping::ProcessorMapping (  const int  n  )

Create a processor mapping array with enough space for n elements. All elements of the mapping are initialized to processor zero, but they should be set by setProcessorAssignment() later.

SAMRAI::hier::ProcessorMapping::ProcessorMapping (  const ProcessorMapping &  mapping  )

Create a new processor mapping and copy the processor assignments from the argument.

SAMRAI::hier::ProcessorMapping::ProcessorMapping (  const tbox::Array< int > &  mapping  )

Create a new processor mapping and get processor assignments from the the tbox::Array<int> argument.

SAMRAI::hier::ProcessorMapping::~ProcessorMapping (   )  [inline]

The destructor simply releases the storage for the mapping.

Member Function Documentation

void SAMRAI::hier::ProcessorMapping::setMappingSize (  const int  n  )

Resize the mapping so that it has n elements. Before it can be used, each element should be set using setProcessorAssignment().

void SAMRAI::hier::ProcessorMapping::setNumberNodes (  const int  n  )  [inline]

Sets the number of nodes to n. IMPORTANT NOTE: This method should only be used for testing purposes. Under normal circumstances, the number of nodes is set by a call to tbox::MPI::getNodes() and should NOT be changed.

int SAMRAI::hier::ProcessorMapping::getProcessorAssignment (  const int  i  )  const [inline]

Return the processor assignment for the specified patch index.

void SAMRAI::hier::ProcessorMapping::setProcessorAssignment (  const int  i, const int  p )  [inline]

Set the processor assignment for the specified patch index.

tbox::Array< int > SAMRAI::hier::ProcessorMapping::getProcessorMapping (   )  const [inline]

Return an tbox::Array<int> of the processor mappings.

void SAMRAI::hier::ProcessorMapping::setProcessorMapping (  const tbox::Array< int > &  mapping  )

Sets the processor mappings from an tbox::Array<int>. Remaps the processors so that patches are not accidentally mapped to non-existent nodes.

int SAMRAI::hier::ProcessorMapping::getNumberOfLocalIndices (   )  const

Return the number of local indices (that is, those indices mapped to the local processor).

const tbox::Array< int > & SAMRAI::hier::ProcessorMapping::getLocalIndices (   )  const

Return an array containing the local indices (that is, those indices mapped to the local processor).

int SAMRAI::hier::ProcessorMapping::getSizeOfMappingArray (   )  const [inline]

Return the total number of indices in the mapping array.

bool SAMRAI::hier::ProcessorMapping::isMappingLocal (  const int  i  )  const [inline]

Check whether the specified index is a local index (that is, mapped to the local processor).
