RS_GRIDDISTRIBUTION_LAYOUT {Integer} {Integer} {Integer} |
|
| Specifies the number of slices in the x, y and z directions.-1 specifies that any number of slices is OK.If a given distribution can not be satisfied, a replicated grid will result.Also see LOCK_DISTRIBUTION. | |
| This keyword cannot be repeated and it expects precisely 3 integers. | |
Default values:
-1 -1 -1 |
DISTRIBUTION_TYPE {Keyword} |
|
| Parallelization strategy. | |
| This keyword cannot be repeated and it expects precisely one keyword. | |
Default value:
AUTOMATIC |
|
List of valid keywords:
|
HALO_REDUCTION_FACTOR {Real} |
|
| Can be used to reduce the halo of the distributed grid (experimental features). | |
| This keyword cannot be repeated and it expects precisely one real. | |
Default value:
1.00000000E+000 |
LOCK_DISTRIBUTION {Logical} |
|
| Expert use only, only basic QS deals correctly with a non-default value.If the distribution is locked, a grid will have the same distribution asthe next finer multigrid (provided it is distributed).If unlocked, all grids can be distributed freely. | |
| This keyword cannot be repeated and it expects precisely one logical. | |
Default value:
.TRUE. |
MAX_DISTRIBUTED_LEVEL {Integer} |
|
| If the multigrid-level of a grid is larger than the parameter, it will not be distributed in the automatic scheme. | |
| This keyword cannot be repeated and it expects precisely one integer. | |
Default value:
2 |
MEMORY_FACTOR {Real} |
|
| A grid will only be distributed if the memory usage for that grid (including halo) is smaller than a replicated grid by this parameter. | |
| This keyword cannot be repeated and it expects precisely one real. | |
Default value:
2.00000000E+000 |
