<H1>Description</H1> |
| 27 |
<B>HPL_dlocswpN</B> |
| 28 |
performs the local swapping operations within a panel. |
| 29 |
The lower triangular N0-by-N0 upper block of the panel is stored in |
| 30 |
no-transpose form (i.e. just like the input matrix itself). |
| 31 |
|
| 32 |
<H1>Arguments</H1> |
| 33 |
<PRE>
|
| 34 |
PANEL (local input/output) HPL_T_panel * |
| 35 |
On entry, PANEL points to the data structure containing the |
| 36 |
panel information. |
| 37 |
</PRE>
|
| 38 |
<PRE>
|
| 39 |
II (local input) const int |
| 40 |
On entry, II specifies the row offset where the column to be |
| 41 |
operated on starts with respect to the panel. |
| 42 |
</PRE>
|
| 43 |
<PRE>
|
| 44 |
JJ (local input) const int |
| 45 |
On entry, JJ specifies the column offset where the column to |
| 46 |
be operated on starts with respect to the panel. |
| 47 |
</PRE>
|
| 48 |
<PRE>
|
| 49 |
WORK (local workspace) double * |
| 50 |
On entry, WORK is a workarray of size at least 2 * (4+2*N0). |
| 51 |
WORK[0] contains the local maximum absolute value scalar, |
| 52 |
WORK[1] contains the corresponding local row index, WORK[2] |
| 53 |
contains the corresponding global row index, and WORK[3] is |
| 54 |
the coordinate of process owning this max. The N0 length max |
| 55 |
row is stored in WORK[4:4+N0-1]; Note that this is also the |
| 56 |
JJth row (or column) of L1. The remaining part of this array |
| 57 |
is used as workspace. |
| 58 |
