| 18 | 1 | equemene | .SH DESCRIPTION |
| 19 | 1 | equemene | \fB\&HPL_dlocswpN\fR |
| 20 | 1 | equemene | performs the local swapping operations within a panel. |
| 21 | 1 | equemene | The lower triangular N0-by-N0 upper block of the panel is stored in |
| 22 | 1 | equemene | no-transpose form (i.e. just like the input matrix itself). |
| 23 | 1 | equemene | .SH ARGUMENTS |
| 24 | 1 | equemene | .TP 8 |
| 25 | 1 | equemene | PANEL (local input/output) HPL_T_panel * |
| 26 | 1 | equemene | On entry, PANEL points to the data structure containing the |
| 27 | 1 | equemene | panel information. |
| 28 | 1 | equemene | .TP 8 |
| 29 | 1 | equemene | II (local input) const int |
| 30 | 1 | equemene | On entry, II specifies the row offset where the column to be |
| 31 | 1 | equemene | operated on starts with respect to the panel. |
| 32 | 1 | equemene | .TP 8 |
| 33 | 1 | equemene | JJ (local input) const int |
| 34 | 1 | equemene | On entry, JJ specifies the column offset where the column to |
| 35 | 1 | equemene | be operated on starts with respect to the panel. |
| 36 | 1 | equemene | .TP 8 |
| 37 | 1 | equemene | WORK (local workspace) double * |
| 38 | 1 | equemene | On entry, WORK is a workarray of size at least 2 * (4+2*N0). |
| 39 | 1 | equemene | WORK[0] contains the local maximum absolute value scalar, |
| 40 | 1 | equemene | WORK[1] contains the corresponding local row index, WORK[2] |
| 41 | 1 | equemene | contains the corresponding global row index, and WORK[3] is |
| 42 | 1 | equemene | the coordinate of process owning this max. The N0 length max |
| 43 | 1 | equemene | row is stored in WORK[4:4+N0-1]; Note that this is also the |
| 44 | 1 | equemene | JJth row (or column) of L1. The remaining part of this array |
| 45 | 1 | equemene | is used as workspace. |
