* Purpose
|
65 |
* =======
|
66 |
*
|
67 |
* HPL_grid_exit marks the process grid object for deallocation. The
|
68 |
* returned error code MPI_SUCCESS indicates successful completion.
|
69 |
* Other error codes are (MPI) implementation dependent.
|

*
|

* Arguments
|
72 |
* =========
|
73 |
*
|
74 |
* GRID (local input/output) HPL_T_grid *
|
75 |
* On entry, GRID points to the data structure containing the
|
76 |
* process grid to be released.
