|
| 77 | 1 | equemene | * Arguments
|
| 78 | 1 | equemene | * =========
|
| 79 | 1 | equemene | *
|
| 80 | 1 | equemene | * PBCST (local input/output) HPL_T_panel *
|
| 81 | 1 | equemene | * On entry, PBCST points to the data structure containing the

|
| 83 | 1 | equemene | *
|
| 84 | 1 | equemene | * IFLAG (local output) int *
|
| 85 | 1 | equemene | * On exit, IFLAG indicates whether or not the broadcast has
|
| 86 | 1 | equemene | * been completed when PBCST is not NULL on entry. In that case,
|
| 87 | 1 | equemene | * IFLAG is left unchanged.
|
| 88 | 1 | equemene | *
|
| 89 | 1 | equemene | * PANEL (local input/output) HPL_T_panel *
|
| 90 | 1 | equemene | * On entry, PANEL points to the data structure containing the
|
| 91 | 1 | equemene | * panel (to be updated) information.
|
| 92 | 1 | equemene | *
|
| 93 | 1 | equemene | * NN (local input) const int
|
| 94 | 1 | equemene | * On entry, NN specifies the local number of columns of the
|
| 95 | 1 | equemene | * trailing submatrix to be updated starting at the current
|
| 96 | 1 | equemene | * position. NN must be at least zero.
