|
* \brief Header file for real operations
|
|
*
|
|
* <pre>
|
|
* -- SuperLU routine (version 4.1) --
|
|
* Univ. of California Berkeley, Xerox Palo Alto Research Center,
|
|
* and Lawrence Berkeley National Lab.
|
|
* November, 2010
|
|
*
|
|
* Global data structures used in LU factorization -
|
|
*
|
|
* nsuper: #supernodes = nsuper + 1, numbered [0, nsuper].
|
|
* (xsup,supno): supno[i] is the supernode no to which i belongs;
|
|
* xsup(s) points to the beginning of the s-th supernode.
|
|
* e.g. supno 0 1 2 2 3 3 3 4 4 4 4 4 (n=12)
|
|
* xsup 0 1 2 4 7 12
|
|
* Note: dfs will be performed on supernode rep. relative to the new
|
|
* row pivoting ordering
|
|
*
|
|
* (xlsub,lsub): lsub[*] contains the compressed subscript of
|
|
* rectangular supernodes; xlsub[j] points to the starting
|
|
* location of the j-th column in lsub[*]. Note that xlsub
|
|
* is indexed by column.
|
|
* Storage: original row subscripts
|
|
*
|
|
* During the course of sparse LU factorization, we also use
|
|
* (xlsub,lsub) for the purpose of symmetric pruning. For each
|
|
* supernode {s,s+1,...,t=s+r} with first column s and last
|
|
* column t, the subscript set
|
|
* lsub[j], j=xlsub[s], .., xlsub[s+1]-1
|
|
* is the structure of column s (i.e. structure of this supernode).
|
|
* It is used for the storage of numerical values.
|
|
* Furthermore,
|
|
* lsub[j], j=xlsub[t], .., xlsub[t+1]-1
|
|
* is the structure of the last column t of this supernode.
|
|
* It is for the purpose of symmetric pruning. Therefore, the
|
|
* structural subscripts can be rearranged without making physical
|
|
* interchanges among the numerical values.
|
|
*
|
|
* However, if the supernode has only one column, then we
|
|
* only keep one set of subscripts. For any subscript interchange
|
|
* performed, similar interchange must be done on the numerical
|
|
* values.
|
|
*
|
|
* The last column structures (for pruning) will be removed
|
|
* after the numercial LU factorization phase.
|
|
*
|
|
* (xlusup,lusup): lusup[*] contains the numerical values of the
|
|
* rectangular supernodes; xlusup[j] points to the starting
|
|
* location of the j-th column in storage vector lusup[*]
|
|
* Note: xlusup is indexed by column.
|
|
* Each rectangular supernode is stored by column-major
|
|
* scheme, consistent with Fortran 2-dim array storage.
|
|
*
|
|
* (xusub,ucol,usub): ucol[*] stores the numerical values of
|
|
* U-columns outside the rectangular supernodes. The row
|
|
* subscript of nonzero ucol[k] is stored in usub[k].
|
|
* xusub[i] points to the starting location of column i in ucol.
|
|
* Storage: new row subscripts; that is subscripts of PA.
