| 20 | 1 | equemene | .SH DESCRIPTION |
| 21 | 1 | equemene | \fB\&HPL_grid_info\fR |
| 22 | 1 | equemene | returns the grid shape and the coordinates in the grid |
| 23 | 1 | equemene | of the calling process. Successful completion is indicated by the |
| 24 | 1 | equemene | returned error code MPI_SUCCESS. Other error codes depend on the MPI |
| 25 | 1 | equemene | implementation. |
| 26 | 1 | equemene | .SH ARGUMENTS |
| 27 | 1 | equemene | .TP 8 |
| 28 | 1 | equemene | GRID (local input) const HPL_T_grid * |
| 29 | 1 | equemene | On entry, GRID points to the data structure containing the |
| 30 | 1 | equemene | process grid information. |
| 31 | 1 | equemene | .TP 8 |
| 32 | 1 | equemene | NPROW (global output) int * |
| 33 | 1 | equemene | On exit, NPROW specifies the number of process rows in the |
| 34 | 1 | equemene | grid. NPROW is at least one. |
| 35 | 1 | equemene | .TP 8 |
| 36 | 1 | equemene | NPCOL (global output) int * |
| 37 | 1 | equemene | On exit, NPCOL specifies the number of process columns in |
| 38 | 1 | equemene | the grid. NPCOL is at least one. |
| 39 | 1 | equemene | .TP 8 |
| 40 | 1 | equemene | MYROW (global output) int * |
| 41 | 1 | equemene | On exit, MYROW specifies my row process coordinate in the |
| 42 | 1 | equemene | grid. MYROW is greater than or equal to zero and less than |
| 43 | 1 | equemene | NPROW. |
| 44 | 1 | equemene | .TP 8 |
| 45 | 1 | equemene | MYCOL (global output) int * |
| 46 | 1 | equemene | On exit, MYCOL specifies my column process coordinate in the |
| 47 | 1 | equemene | grid. MYCOL is greater than or equal to zero and less than |
| 48 | 1 | equemene | NPCOL. |
