Detailed Description

Epetra_BlockMap: A class for partitioning block element vectors and matrices.

It is often the case that multiple matrix and vector objects have an identical distribution

of elements on a parallel machine. The Epetra_BlockMap class keeps information that describes this distribution for matrices and vectors that have block elements. The definition of an element can vary depending on the situation. For vectors (and multi-vectors), an element is a span of one or more contiguous entries. For matrices, it is a span of one or more matrix rows. More generally, an element in the BlockMap class is an ordered list of points. (NOTE: Points do not have global ID's.) Two additional definitions useful in understanding the BlockMap class follow:

BlockMap - A distributed ordered list of elements.
First Point - First ordered point in an element

This class has a variety of constructors that can be separated into two categories:

Fixed element size constructors: All map elements have an identical size. This corresponds to a block partitioning of matrices and vectors where the element size is the same for all elements. A common example is multiple degrees of freedom per mesh node in finite element computations where the number of degrees of freedom is the same for all nodes.
Variable element size constructor: Map element sizes may vary and are individually defined via a list of element sizes. This is the most general case and corresponds to a variable block partitioning of the matrices and vectors. A common example is multiple degrees of freedom per mesh node in finite element computations where the number of degrees of freedom varies. This happens, for example, if regions have differing material types or there are chemical reactions in the simulation.

Epetra_BlockMap allows the storage and retrieval of the following information. Depending on the constructor that is used, some of the information is defined by the user and some is determined by the constructor. Once an Epetra_BlockMap is constructed any of the following can be obtained by calling a query function that has the same name as the attribute, e.g. to get the value of NumGlobalElements, you can call a function NumGlobalElements(). For attributes that are lists, the query functions return the list values in a user allocated array.

NumGlobalElements - The total number of elements across all processors. If this parameter and NumMyElements are both passed in to the constructor, one of the three cases will apply:
1. If NumGlobalElements = NumMyElements (and not equal to zero) the map is defined to be a local replicated map. In this case, objects constructed using this map will be identically replicated across all processors in the communicator.
2. If NumGlobalElements = -1 and NumMyElements is passed in then NumGlobalElements will be computed as the sum of NumMyElements across all processors.
3. If neither of the above is true, NumGlobalElements will be checked against the sum of NumMyElements across all processors. An error is issued if the comparison is not equal.
NumMyElements - The number of elements owned by the calling processor.
MyGlobalElements - A list of length NumMyElements that contains the global element IDs of the elements owned by the calling processor.
ElementSize - The size of elements if the size of all elements is the same. This will be the case if the query function ConstantElementSize() returns true. Otherwise this value will be set to zero.
ElementSizeList - A list of the element sizes for elements owned by the calling processor. This list is always accessible, even if the element sizes are all one or of constant value. However, in these cases, the ElementSizeList will not be generated unless a query for the list is called.
IndexBase - The base integer value for indexed array references. Typically this is 0 for C/C++ and 1 for Fortran, but it can be set to any integer value.
Comm - The Epetra_Comm communicator. This communicator can in turn be queried for processor rank and size information.

In addition to the information above that is passed in to or created by the Epetra_BlockMap constructor, the following attributes are computed and available via query to the user using the same scheme as above, e.g., use NumGlobalPoints() to get the value of NumGlobalPoints.

NumGlobalPoints - The total number of points across all processors.
NumMyPoints - The number of points on the calling processor.
MinAllGID - The minimum global index value across all processors.
MaxAllGID - The maximum global index value across all processors.
MinMyGID - The minimum global index value on the calling processor.
MaxMyGID - The maximum global index value on the calling processor.
MinLID - The minimum local index value on the calling processor.
MaxLID - The maximum local index value on the calling processor.
MinElementSize - The minimum element size across all processors.
MaxElementSize - The maximum element size across all processors.

The following functions allow boolean tests for certain properties.

ConstantElementSize() - Returns true if the element size for this map is the same for all elements.
LinearMap() - Returns true if the elements are distributed linear across processors, i.e., processor 0 gets the first n/p elements, processor 1 gets the next n/p elements, etc. where n is the number of elements and p is the number of processors.
DistributedGlobal() - Returns true if the element space of the map spans more than one processor. This will be true in most cases, but will be false on in serial and for objects that are created via the derived Epetra_LocalMap class.

Warning: A Epetra_Comm object is required for all Epetra_BlockMap constructors.

{error handling}

Most methods in Epetra_BlockMap return an integer error code. If the error code is 0, then no error occurred. If > 0 then a warning error occurred. If < 0 then a fatal error occurred.

Epetra_BlockMap constructors will throw an exception of an error occurrs. These exceptions will alway be negative integer values as follows:

-1 NumGlobalElements < -1. Should be >= -1 (Should be >= 0 for first BlockMap constructor).
-2 NumMyElements < 0. Should be >= 0.
-3 ElementSize <= 0. Should be > 0.
-4 Invalid NumGlobalElements. Should equal sum of MyGlobalElements, or set to -1 to compute automatically.
-5 Minimum global element index is less than index base.
-99 Internal Epetra_BlockMap error. Contact developer.

For robust code, Epetra_BlockMap constructor calls should be caught using the try {...} catch {...} mechanism. For example:

  try {

    Epetra_BlockMap * map = new Epetra_BlockMap(NumGlobalElements, ElementSize, IndexBase, Comm);
  }
  catch (int Error) {
    if (Error==-1) { // handle error }
    if (Error==-2) ...

Note

{ In the current implementation, Epetra_BlockMap is the base class for:

Epetra_Map.
Epetra_LocalBlockMap.

		const Epetra_Comm &	Comm
	)

Epetra_BlockMap constructor for a Epetra-defined uniform linear distribution of constant size elements.

Creates a map that distributes NumGlobalElements elements evenly across all processors in the Epetra_Comm communicator. If NumGlobalElements does not divide exactly into the number of processors, the first processors in the communicator get one extra element until the remainder is gone.

The elements are defined to have a constant fixed size specified by ElementSize.

Parameters

In	NumGlobalElements - Number of elements to distribute.
In	ElementSize - Number of points or vector entries per element.
In	IndexBase - Minimum index value used for arrays that use this map. Typically 0 for C/C++ and 1 for Fortran.
In	Comm - Epetra_Comm communicator containing information on the number of processors.

Returns: Pointer to a Epetra_BlockMap object.

int Epetra_BlockMap::RemoteIDList	(	int	NumIDs,
		const int *	GIDList,
		int *	PIDList,
		int *	LIDList
	)		const

inline

Returns the processor IDs and corresponding local index value for a given list of global indices.

For each element (GID) of a given list of global element numbers (stored in GIDList) of length NumIDs, this function returns (in PIDList) the ID (rank) of the processor that owns the GID for this map and returns the local index (in LIDList) of the GID on that processor.

If a GID is present on more than one processor, the lowest rank processor ID is used, as is the LID for that processor. If a GID is not present on any processor, the corresponding PID will return as -1.

Epetra_BlockMap * Epetra_BlockMap::RemoveEmptyProcesses ( ) const

Return a new BlockMap with processes with zero elements removed.

Warning: This method is only for expert users. Understanding how to use this method correctly requires some familiarity with semantics of MPI communicators.; We make no promises of backwards compatibility for this method. It may go away or change at any time.

This method first computes a new communicator, which contains only those processes in this Map's communicator (the "original communicator") that have a nonzero number of elements in this BlockMap (the "original BlockMap"). It then returns a new BlockMap distributed over the new communicator. The new BlockMap represents the same distribution as the original BlockMap, except that processes containing zero elements are not included in the new BlockMap or its communicator. On processes not included in the new BlockMap or communicator, this method returns NULL.

The returned BlockMap always has a distinct communicator from this BlockMap's original communicator. The new communicator contains a subset of processes from the original communicator. Even if the number of processes in the new communicator equals the number of processes in the original communicator, the new communicator is distinct. (In an MPI implementation, the new communicator is created using MPI_Comm_split.)

This method must be called collectively on the original communicator. It leaves the original Map and communicator unchanged.

This method was intended for applications such as algebraic multigrid or other multilevel preconditioners. Construction of each level of the multilevel preconditioner typically requires constructing sparse matrices, which in turn requires all-reduces over all participating processes at that level. Matrix sizes at successively coarser levels shrink geometrically. At the coarsest levels, some processes might be left with zero rows of the matrix, or the multigrid implementation might "rebalance" (redistribute the matrix) and intentionally leave some processes with zero rows. Removing processes with zero rows makes the all-reduces and other communication operations cheaper.

Definition at line 1553 of file Epetra_BlockMap.cpp.

Epetra_BlockMap * Epetra_BlockMap::ReplaceCommWithSubset ( const Epetra_Comm * Comm ) const

Replace this BlockMap's communicator with a subset communicator.

Warning: This method is only for expert users. Understanding how to use this method correctly requires some familiarity with semantics of MPI communicators.; We make no promises of backwards compatibility for this method. It may go away or change at any time.

Precondition: The input communicator's processes are a subset of this BlockMap's current communicator's processes.; On processes which are not included in the input communicator, the input communicator is null.

This method must be called collectively on the original communicator. It leaves the original BlockMap and communicator unchanged.

Note: This method differs from removeEmptyProcesses(), in that it does not assume that excluded processes have zero entries. For example, one might wish to remove empty processes from the row BlockMap of a CrsGraph using removeEmptyProcesses(), and then apply the resulting subset communicator to the column, domain, and range Maps of the same graph. For the latter three Maps, one would in general use this method instead of removeEmptyProcesses(), giving the new row BlockMap's communicator to this method.
