Detailed Description

Epetra_CrsGraph: A class for constructing and using sparse compressed row graphs. 

Epetra_CrsGraph enables the piecewise construction and use of sparse matrix graphs (the integer structure without
values) where entries are intended for row access.

Epetra_CrsGraph is an attribute of all Epetra row-based matrix classes, defining their nonzero structure and also
holding their Epetra_Map attributes.

Constructing Epetra_CrsGraph objects

Constructing Epetra_CrsGraph objects is a multi-step process. The basic steps are as follows:

  1. Create Epetra_CrsGraph instance, including some initial storage, via constructor. In addition to the copy constructor, Epetra_CrsGraph has four different constructors. All four of these constructors have an argument, StaticProfile, which by default is set to false. If it is set to true, then the profile (the number of indices per row as defined by NumIndicesPerRow) will be rigidly enforced. Although this takes away flexibility, it allows a single array to be allocated for all indices. This decreases memory fragmentation and improves performance across many operations. A more detailed discussion of the StaticProfile option is found below.
    1. User-provided row map, variable nonzero profile: This constructor is used to define the row distribution of the graph and specify a varying number of nonzero entries per row. It is best to use this constructor when the user will be inserting entries using global index values and wants every column index to be included in the graph. Note that in this case, the column map will be built for the user when FillComplete() is called. This constructor is also appropriate for when there is a large variation in the number of indices per row. If this is not the case, the next constructor may be more convenient to use.
    2. User-provided row map, fixed nonzero profile: This constructor is used to define the row distribution of the graph and specify a fixed number of nonzero entries per row. It is best to use this constructor when the user will be inserting entries using global index values and wants every column index to be included in the graph. Note that in this case, the column map will be built for the user when FillComplete() is called. This constructor is also appropriate for when there is little or no variation in the number of indices per row.
    3. User-provided row map, user-provided column map and variable nonzero profile: This constructor is used to define the row and column distribution of the graph, and specify a varying number of nonzero entries per row. It is best to use this constructor when the user will be inserting entries and already knows which columns of the matrix should be included on each processor. Note that in this case, the column map will not be built for the user when FillComplete() is called. Also, if the user attempts to insert a column index whose GID is not part of the column map on that process, the index will be discarded. This property can be used to "filter out" column entries that should be ignored. This constructor is also appropriate for when there is a large variation in the number of indices per row. If this is not the case, the next constructor may be more convenient to use.
    4. User-provided row map, user-provided column map and fixed nonzero profile: This constructor is used to define the row and column distribution of the graph, and specify a fixed number of nonzero entries per row. It is best to use this constructor when the user will be inserting entries and already knows which columns of the matrix should be included on each processor. Note that in this case, the column map will not be built for the user when FillComplete() is called. Also, if the user attempts to insert a column index whose GID is not part of the column map on that process, the index will be discarded. This constructor is also appropriate for when there is little or no variation in the number of indices per row.
  2. Enter row and column entry information via calls to the InsertGlobalIndices method.
  3. Complete construction via FillComplete call, which performs the following tasks:
    1. Transforms indices to local index space (after this, IndicesAreLocal()==true)

Performance Enhancement Issues

The Epetra_CrsGraph class attempts to address four basic types of situations, depending on the user's primary concern:

  1. Simple, flexible construction over minimal memory use or control of column indices: In this case the user wants to provide only a row distribution of the graph and insert indices without worrying about memory allocation performance. This type of user is best served by the constructor that requires only a row map, and a fixed number of indices per row. In fact, setting NumIndicesPerRow=0 is probably the best option.
  2. Stronger control over memory allocation performance and use over flexibility and simplicity: In this case the user explicitly set StaticProfile to true and will provide values, either a single global int or an array of int's, for NumIndicesPerRow, such that the actual number of indices submitted to the graph will not exceed the estimates. Because we know that NumIndicesPerRow will not be exceeded, we can pre-allocate all of the storage for the graph as a single array. This is typically much more efficient.
  3. Explicit control over column indices: In this case the user prescribes the column map. Given the column map, any index that is submitted for entry into the graph will be included only if they are present in the list of GIDs for the column map on the processor that submits the index. This feature allows the user to define a filter such that only certain columns will be kept. The user also prescribes the local ordering via this technique, since the ordering of GIDs in the column map imposes the local ordering.
  4. Construction using local indices only: In some situations, users may want to build a graph using local index values only. In this case, the user must explicitly assign GIDs. This is done by prescribing the column map, in the same way as the previous situation.

Notes:

Epetra_Map attributes

Epetra_CrsGraph objects have four Epetra_Map attributes.

The Epetra_Map attributes can be obtained via these accessor methods:

It is important to note that while the row-map and the range-map are often the same, the column-map and the domain-map are almost never the same. The set of entries in a distributed column-map almost always form overlapping sets, with entries being associated with more than one processor. A domain-map, on the other hand, must be a 1-to-1 map, with entries being associated with only a single processor.

Global versus Local indices

After creation and before FillComplete() has been called, the column-indices of the graph are in the global space as received from the user. One of the tasks performed by FillComplete() is to transform the indices to a local index space. The query methods IndicesAreGlobal() and IndicesAreLocal() return true or false depending on whether this transformation has been performed or not.

Note the behavior of several graph methods:

Note that even after a graph is constructed, it is possible to add or remove entries. However, FillComplete must then be called again to restore the graph to a consistent state.

Epetra_CrsGraph::Epetra_CrsGraph ( Epetra_DataAccess  CV,
const Epetra_BlockMap &  RowMap,
const int *  NumIndicesPerRow,
bool  StaticProfile = false 
)

Epetra_CrsGraph constuctor with variable number of indices per row.

Creates a Epetra_CrsGraph object and allocates storage.

Parameters
CV- (In) A Epetra_DataAccess enumerated type set to Copy or View.
RowMap- (In) An Epetra_BlockMap (or Epetra_Map or Epetra_LocalMap) listing the rows that this processor will contribute to.In
NumIndicesPerRow- (In) An integer array of length NumMyRows such that NumIndicesPerRow[i] indicates the (approximate if StaticProfile=false) number of entries in the ith row.
StaticProfile- (In) Optional argument that indicates whether or not NumIndicesPerRow should be interpreted as an exact count of nonzeros, or should be used as an approximation. By default this value is false, allowing the profile to be determined dynamically. If the user sets it to true, then the memory allocation for the Epetra_CrsGraph object will be done in one large block, saving on memory fragmentation and generally improving the performance of matrix multiplication and solve kernels.

const Epetra_BlockMap &  RangeMap 
)

Transform to local index space using specified Domain/Range maps. Perform other operations to allow optimal matrix operations.

Performs this sequence of operations:

  1. Transform indices to local index space
  2. Sort column-indices within each row
  3. Compress out any redundant indices within rows
  4. Compute global data such as num-nonzeros, maximum row-lengths, etc.

int Epetra_CrsGraph::OptimizeStorage ( )

Make consecutive row index sections contiguous, minimize internal storage used for constructing graph.

After construction and during initialization (when indices are being added via InsertGlobalIndices() etc.), the column- indices for each row are held in a separate piece of allocated memory. This method moves the column-indices for all rows into one large contiguous array and eliminates internal storage that is not needed after graph construction. Calling this method can have a significant impact on memory costs and machine performance.

If this object was constructed in View mode then this method can't make non-contiguous indices contiguous and will return a warning code of 1 if the viewed data isn't already contiguous.

Returns
Integer error code, set to 0 if successful.
Precondition
Filled()==true.
If CV=View when the graph was constructed, then this method will be effective only if the indices of the graph were already contiguous. In this case, the indices are left untouched and internal storage for the graph is minimized.
Postcondition
StorageOptimized()==true, if successful

void Epetra_CrsGraph::SortGhostsAssociatedWithEachProcessor ( bool  Flag)
inline

Forces FillComplete() to locally order ghostnodes associated with each remote processor in ascending order.

To be compliant with AztecOO, FillComplete() already locally orders ghostnodes such that information received from processor k has a lower local numbering than information received from processor j if k is less than j. SortGhostsAssociatedWithEachProcessor(True) further forces FillComplete() to locally number all ghostnodes received from processor k in ascending order. That is, the local numbering of b is less than c if the global numbering of b is less than c and if both b and c are owned by the same processor. This is done to be compliant with some limited block features within ML. In particular, some ML features require that a block structure of the matrix be maintained even within the ghost variables.
