3.0) -- Univ. of California Berkeley, Xerox Palo Alto Research Center, and Lawrence Berkeley National Lab. October 15, 2003</pre><p><pre> Global data structures used in LU factorization -</pre><p><pre> 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</pre><p><pre> (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</pre><p><pre> 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.</pre><p><pre> 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.</pre><p><pre> The last column structures (for pruning) will be removed after the numercial LU factorization phase.</pre><p><pre> (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.</pre><p><pre> (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. </pre> <hr><h2>Typedef Documentation</h2><a class="anchor" name="b6fd6105e64ed14a0c9281326f05e623"></a><!-- doxytag: member="slu_ddefs.h::int_t" ref="b6fd6105e64ed14a0c9281326f05e623" args="" --><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">typedef int <a class="el" href="slu__zdefs_8h.html#b6fd6105e64ed14a0c9281326f05e623">int_t</a> </td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p> </td> </tr></table><hr><h2>Function Documentation</h2><a class="anchor" name="c1bba297faf9fa0cb8d4e945138b5a21"></a><!-- doxytag: member="slu_ddefs.h::check_tempv" ref="c1bba297faf9fa0cb8d4e945138b5a21" args="(int, double *)" --><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">void check_tempv </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">int </td> <td class="mdname" nowrap>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>double * </td> <td class="mdname" nowrap></td> </tr> <tr> <td class="md"></td> <td class="md">) </td> <td class="md" colspan="2"></td> </tr> </table> </td> </tr>⌨️ 快捷键说明
