SetSimtBlockDim
Function Usage
Sets the dimension of a SIMT thread block, that is, the number of threads in the thread block of the Vector unit involved in computation. The dimension is represented by the Dim3 structure. Dim3 is a structure that contains three UInt32 fields: x, y, and z. It represents the number of threads in a thread block in the x, y, and z dimensions.
For example, block_dim.x, block_dim.y, and block_dim.z represent the number of threads in the x, y, and z dimensions of a thread block, respectively.

Input |
Dimension of a thread block, represented by a Dim3 structure. Dim3 is a structure that contains three UInt32 fields: x, y, and z. It represents the number of threads in a thread block in the x, y, and z dimensions. |
The Dim3 structure is defined as follows:
struct Dim3 {
uint32_t x, y, z;
Dim3(const uint32_t dim3_x, const uint32_t dim3_y = 1, const uint32_t dim3_z = 1) : x(dim3_x), y(dim3_y), z(dim3_z) {
}
};
Note: Dim3 is a structure that contains three uint32 fields: x, y, and z. In SIMT, it can represent the number of threads in a block in the x, y, and z dimensions, or the number of thread blocks in a grid in the x, y, and z dimensions.
Returns
ge::GRAPH_SUCCESS on success.
