HPL_pdgesv(3) HPL Library Functions HPL_pdgesv(3) NAME HPL_pdgesv - Solve A x = b. SYNOPSIS #include "hpl.h" void HPL_pdgesv( HPL_T_grid * GRID, HPL_T_palg * ALGO, HPL_T_pmat * A ); DESCRIPTION HPL_pdgesv factors a N+1-by-N matrix using LU factorization with row par- tial pivoting. The main algorithm is the "right looking" variant with or without look-ahead. The lower triangular factor is left unpivoted and the pivots are not returned. The right hand side is the N+1 column of the coefficient matrix. ARGUMENTS GRID (local input) HPL_T_grid * On entry, GRID points to the data structure containing the process grid information. ALGO (global input) HPL_T_palg * On entry, ALGO points to the data structure containing the algo- rithmic parameters. A (local input/output) HPL_T_pmat * On entry, A points to the data structure containing the local array information. SEE ALSO HPL_pdgesv0 (3), HPL_pdgesvK1 (3), HPL_pdgesvK2 (3), HPL_pdtrsv (3).
