Override global thread allocation.
Override global thread allocation. Typically used to create a thread per tensor element in a field, though the field may be illusory, not corresponding to any input or output field. This gives you raw control over thread allocation.
Each thread can see its identity in the global thread space from the constants:
_layer _row _column _tensorElement
Basically this creates a thread for each element in a tensor field.
The shape of the global threads allocated. This may be 1D, 2D or 3D, and each thread can see its identity with the _layer, _row, and _column constants.
The shape of the tensors in the (possibly illusory) field. One thread is created for each tensor in that field.
Statement for the global thread allocation override.
