PW_TRANSFER
DEBUG {Logical} |
|
Do the FFT in debug mode in all cases | |
This keyword cannot be repeated and it expects precisely one logical. | |
The lone keyword behaves as a switch to
.TRUE. |
|
Default value:
.FALSE. |
GRID {Integer} {Integer} {Integer} |
|
Specify the number of grid points (not all grid points are allowed) | |
This keyword cannot be repeated and it expects precisely 3 integers. | |
Default values:
128 128 128 |
N_LOOP {Integer} |
|
Number of pw_transfers (backward&forward) being timed | |
This keyword cannot be repeated and it expects precisely one integer. | |
Default value:
100 |
PW_GRID {Keyword} |
|
What kind of PW_GRID should be employed | |
This keyword cannot be repeated and it expects precisely one keyword. | |
Default value:
NS-FULLSPACE |

List of valid keywords:
|
PW_GRID_BLOCKED {Keyword} |
|
Expert use only, leave the default...Can be used to set the distribution in g-space for the pw grids and their FFT. | |
This keyword cannot be repeated and it expects precisely one keyword. | |
Default value:
FALSE |
|
List of valid keywords:
|
PW_GRID_LAYOUT {Integer} {Integer} |

Default values:
-1 -1 |
PW_GRID_LAYOUT_ALL {Logical} |
|
loop overal all PW_GRID_LAYOUTs that are compatible with a given number of CPUs | |
This keyword cannot be repeated and it expects precisely one logical. | |
The lone keyword behaves as a switch to
.TRUE. |
