◆ sp_ienv()

int sp_ienv ( int  ispec)
    Purpose   
    =======   

    sp_ienv() is inquired to choose machine-dependent parameters for the
    local environment. See ISPEC for a description of the parameters.   

    This version provides a set of parameters which should give good,   
    but not optimal, performance on many of the currently available   
    computers.  Users are encouraged to modify this subroutine to set   
    the tuning parameters for their particular machine using the option   
    and problem size information in the arguments.   

    Arguments   
    =========   

    ISPEC   (input) int
            Specifies the parameter to be returned as the value of SP_IENV.   
            = 1: the panel size w; a panel consists of w consecutive
                 columns of matrix A in the process of Gaussian elimination.
                 The best value depends on machine's cache characters.
            = 2: the relaxation parameter relax; if the number of
                 nodes (columns) in a subtree of the elimination tree is less
                 than relax, this subtree is considered as one supernode,
                 regardless of their row structures.
            = 3: the maximum size for a supernode in complete LU;
            = 4: the minimum row dimension for 2-D blocking to be used;
            = 5: the minimum column dimension for 2-D blocking to be used;
            = 6: the estimated fills factor for L and U, compared with A;
            = 7: the maximum size for a supernode in ILU.

   (SP_IENV) (output) int
            >= 0: the value of the parameter specified by ISPEC   
            < 0:  if SP_IENV = -k, the k-th argument had an illegal value.

◆ sp_preorder()

void sp_preorder ( superlu_options_t options,
SuperMatrix A,
int *  perm_c,
int *  etree,
SuperMatrix AC 
)
Purpose
=======

sp_preorder() permutes the columns of the original matrix. It performs
the following steps:

   1. Apply column permutation perm_c[] to A's column pointers to form AC;

   2. If options->Fact = DOFACT, then
      (1) Compute column elimination tree etree[] of AC'AC;
      (2) Post order etree[] to get a postordered elimination tree etree[],
          and a postorder permutation post[];
      (3) Apply post[] permutation to columns of AC;
      (4) Overwrite perm_c[] with the product perm_c * post.

Arguments
=========

options (input) superlu_options_t*
        Specifies whether or not the elimination tree will be re-used.
        If options->Fact == DOFACT, this means first time factor A, 
        etree is computed, postered, and output.
        Otherwise, re-factor A, etree is input, unchanged on exit.

A       (input) SuperMatrix*
        Matrix A in A*X=B, of dimension (A->nrow, A->ncol). The number
        of the linear equations is A->nrow. Currently, the type of A can be:
        Stype = NC or SLU_NCP; Mtype = SLU_GE.
        In the future, more general A may be handled.

perm_c  (input/output) int*
        Column permutation vector of size A->ncol, which defines the 
        permutation matrix Pc; perm_c[i] = j means column i of A is 
        in position j in A*Pc.
        If options->Fact == DOFACT, perm_c is both input and output.
        On output, it is changed according to a postorder of etree.
        Otherwise, perm_c is input.

etree   (input/output) int*
        Elimination tree of Pc'*A'*A*Pc, dimension A->ncol.
        If options->Fact == DOFACT, etree is an output argument,
        otherwise it is an input argument.
        Note: etree is a vector of parent pointers for a forest whose
        vertices are the integers 0 to A->ncol-1; etree[root]==A->ncol.

AC      (output) SuperMatrix*
        The resulting matrix after applied the column permutation
        perm_c[] to matrix A. The type of AC can be:
