A distributed graph accessed by rows (adjacency lists) and stored sparsely.

This class implements a distributed-memory parallel sparse graph. It provides access by rows to the elements of the graph, as if the local data were stored in compressed sparse row format (adjacency lists, in graph terms). (Implementations are not required to store the data in this way internally.) This class has an interface like that of Epetra_CrsGraph, but also allows insertion of data into nonowned rows, much like Epetra_FECrsGraph.
Before reading the rest of this documentation, it helps to know something about the Teuchos memory management classes, in particular Teuchos::RCP, Teuchos::ArrayRCP, and Teuchos::ArrayView. You should also know a little bit about MPI (the Message Passing Interface for distributed-memory programming). You won't have to use MPI directly to use CrsGraph, but it helps to be familiar with the general idea of distributed storage of data over a communicator. Finally, you should read the documentation of Map.
Graph entries can be added using either local or global coordinates for the indices. The accessors isGloballyIndexed() and isLocallyIndexed() indicate whether the indices are currently stored as global or local indices. Many of the class methods are divided into global and local versions, which differ only in whether they accept/return indices in the global or local coordinate space. Some of these methods may only be used if the graph coordinates are in the appropriate coordinates. For example, getGlobalRowView() returns a View to the indices in global coordinates; if the indices are not in global coordinates, then no such View can be created.
The global/local distinction does distinguish between operation on the global/local graph. Almost all methods operate on the local graph, i.e., the rows of the graph associated with the local node, per the distribution specified by the row map. Access to non-local rows requires performing an explicit communication via the import/export capabilities of the CrsGraph object; see DistObject. However, the method insertGlobalIndices() is an exception to this rule, as non-local rows are allowed to be added via the local graph. These rows are stored in the local graph and communicated to the appropriate node on the next call to globalAssemble() or fillComplete() (the latter calls the former).

This View gets used only on host. However, making this literally a host View (of Kokkos::HostSpace) causes inexplicable test failures only on CUDA. Thus, I left it as a HostMirror, which means (given Trilinos' current UVM requirement) that it will be a UVM allocation.

If false, fills clone using global indices and does not provide a column map. By default, will use local indices only if this graph is using local indices.true, calls fillComplete() on the cloned CrsGraph object, with parameters from params sublist "CrsGraph". The domain map and range maps passed to fillComplete() are those of the map being cloned, if they exist. Otherwise, the row map is used. True if and only if CrsGraph is identical to this CrsGraphThis performs exact matches on objects with in the graphs.

Get offsets of the diagonal entries in the graph.
This method helps users optimize Tpetra::CrsMatrix::getLocalDiagCopy and Tpetra::Experimental::BlockCrsMatrix::getLocalDiagCopy, for several calls when the graph's structure does not change. The method fills an array of offsets of the local diagonal entries in the matrix. getLocalDiagCopy uses the offsets to extract the diagonal entries directly, without needing to search for them using Map lookups and search in each row of the graph.
The output array's contents are not defined in any other context other than for use in getLocalDiagCopy. For example, you should not rely on offsets(i) being the index of the diagonal entry in the views returned by Tpetra::CrsMatrix::getLocalRowView. This may be the case, but it need not be. (For example, we may choose to optimize the lookups down to the optimized storage level, in which case the offsets will be computed with respect to the underlying storage format, rather than with respect to the views.)
Changes to the graph's structure, or calling fillComplete on the graph (if its structure is not already fixed), may make the output array's contents invalid. "Invalid" means that you must call this method again to recompute the offsets.

| bool & | boundSameForAllLocalRows | ||
| ) | const |
Get an upper bound on the number of entries that can be stored in each row.
When a CrsGraph is constructed, callers must give an upper bound on the number of entries in each local row. They may either supply a single integer which is the upper bound for all local rows, or they may give an array with a possibly different upper bound for each local row.
This method returns the upper bound for each row. If numEntriesPerLocalRowBound is Teuchos::null on output and boundSameForAllLocalRows is true on output, then numEntriesAllLocalRowsBound is the upper bound for all local rows. If boundSameForAllLocalRows is false on output, then numEntriesPerLocalRowBound has zero or more entries on output, and numEntriesPerLocalRowBound[i_local] is the upper bound for local row i_local.
The output argument boundSameForAllLocalRows is conservative; it only tells us whether boundForAllLocalRows has a meaningful value on output. We don't necessarily check whether all entries of boundPerLocalRow are the same.

Replace the graph's current column Map with the given Map.
This only replaces the column Map. It does not change the graph's current column indices, or otherwise apply a permutation. For example, suppose that before calling this method, the calling process owns a row containing local column indices [0, 2, 4]. These indices do not change, nor does their order change, as a result of calling this method.

However, if this graph will be used in Xpetra, Ifpack2, or MueLu, the column map's list of global indices must follow "Aztec ordering": locally owned GIDs (same order as in domain map), followed by remote GIDs (in order of owning proc, and sorted within each proc). |

Remove processes owning zero rows from the Maps and their communicator.
| newMap | [in] This must be the result of calling the removeEmptyProcesses() method on the row Map. If it is not, this method's behavior is undefined. This pointer will be null on excluded processes. |
This method satisfies the strong exception guarantee, as long the destructors of Export, Import, and Map do not throw exceptions. This means that either the method returns normally (without throwing an exception), or there are no externally visible side effects. However, this does not guarantee no deadlock when the graph's original communicator contains more than one process. In order to prevent deadlock, you must still wrap this call in a try/catch block and do an all-reduce over all processes in the original communicator to test whether the call succeeded. This safety measure should usually be unnecessary, since the method call should only fail on user error or failure to allocate memory.

Remove processes which contain no entries in this object's Map.
On input, this object is distributed over the Map returned by getMap() (the "original Map," with its communicator, the "original communicator"). The input newMap of this method must be the same as the result of calling getMap()->removeEmptyProcesses(). On processes in the original communicator which contain zero entries ("excluded processes," as opposed to "included processes"), the input newMap must be Teuchos::null (which is what getMap()->removeEmptyProcesses() returns anyway).
On included processes, reassign this object's Map (that would be returned by getMap()) to the input newMap, and do any work that needs to be done to restore correct semantics. On excluded processes, free any data that needs freeing, and do any other work that needs to be done to restore correct semantics.
This method has collective semantics over the original communicator. On exit, the only method of this object which is safe to call on excluded processes is the destructor. This implies that subclasses' destructors must not contain communication operations.

Whether the implementation's instance promises always to have a constant number of packets per LID (local index), and if so, how many packets per LID there are.
If this method returns zero, the instance says that it might possibly have a different number of packets for each LID (local index) to send or receive. If it returns nonzero, the instance promises that the number of packets is the same for all LIDs, and that the return value is this number of packets per LID.
The default implementation of this method returns zero. This does not affect the behavior of doTransfer() in any way. If a nondefault implementation returns nonzero, doTransfer() will use this information to avoid unnecessary allocation and / or resizing of arrays.

Reallocate imports_ if needed.
This unfortunately must be declared protected, for the same reason that imports_ is declared protected.
| newSize | [in] New size of imports_. |
| verbose | [in] Whether to print verbose debugging output to stderr on every (MPI) process in the communicator. |
| prefix | [in] If verbose is true, then this is a nonnull prefix to print at the beginning of each line of verbose debugging output. Otherwise, not used. |
We don't need a "reallocExportsIfNeeded" method, because exports_ always gets passed into packAndPrepare() by nonconst reference. Thus, that method can resize the DualView without needing to call other DistObject methods.

Nonmember CrsGraph constructor that fuses Import and fillComplete().
| CrsGraphType | A specialization of CrsGraph. |
A common use case is to create an empty destination CrsGraph, redistribute from a source CrsGraph (by an Import or Export operation), then call fillComplete() on the destination CrsGraph. This constructor fuses these three cases, for an Import redistribution.
Fusing redistribution and fillComplete() exposes potential optimizations. For example, it may make constructing the column Map faster, and it may avoid intermediate unoptimized storage in the destination CrsGraph.
The resulting graph is fill complete (in the sense of isFillComplete()) and has optimized storage (in the sense of isStorageOptimized()). By default, its domain Map is the domain Map of the source graph, and its range Map is the range Map of the source graph.
| sourceGraph | [in] The source graph from which to import. The source of an Import must have a nonoverlapping distribution. |

The maximum number of entries to allow in each locally owned row, per row.
This comes in as an argument to some of the graph's constructors. Either this or numAllocForAllRows_ is used, but not both. allocateIndices(), setAllIndices(), and expertStaticFillComplete() all deallocate this array once they are done with it.
This is a host View because it is only ever used on the host. It has the HostMirror type for backwards compatibility; this used to be a DualView with default layout, so making this a HostMirror ensures that we can still take it directly by assignment from the constructors that take DualView, without a deep copy.
This array only exists on a process before the graph's indices are allocated on that process. After that point, it is discarded, since the graph's allocation implicitly or explicitly represents the same information.
FIXME (mfh 07 Aug 2014) We want graph's constructors to allocate, rather than doing lazy allocation at first insert. This will make both k_numAllocPerRow_ and numAllocForAllRows_ obsolete.

Only the first k_numRowEntries_(i_lcl) of these entries are actual valid column indices. Any remaining entries are "extra space." If the graph's storage is packed, then there is no extra space, and the k_numRowEntries_ array is invalid.
If it is allocated, k_rowPtrs_ has length getNodeNumRows()+1. The k_numRowEntries_ array has has length getNodeNumRows(), again if it is allocated.

Status of the graph's storage, when not in a fill-complete state.
The phrase "When not in a fill-complete state" is important. When the graph is fill complete, it always uses 1-D "packed" storage. However, if the "Optimize Storage" parameter to fillComplete was false, the graph may keep unpacked 1-D storage around and resume it on the next resumeFill call.

Whether to require makeColMap() (and therefore fillComplete()) to order column Map GIDs associated with each remote process in ascending order.
makeColMap() always groups remote GIDs by process rank, so that all remote GIDs with the same owning rank occur contiguously. By default, it always sorts remote GIDs in increasing order within those groups. This behavior differs from Epetra, which does not sort remote GIDs with the same owning process.
This is true by default, which means "sort remote GIDs." If you don't want to sort (for compatibility with Epetra), call sortGhostColumnGIDsWithinProcessBlock(false).
