-- 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.
