Struct ClusterLaunchParams 

pub struct ClusterLaunchParams {
    pub grid: Dim3,
    pub block: Dim3,
    pub cluster: ClusterDim,
    pub shared_mem_bytes: u32,
}

Launch parameters including thread block cluster configuration.

Extends the standard grid/block configuration with a cluster dimension. The grid dimensions must be evenly divisible by the cluster dimensions.

Fields

grid: Dim3

Grid dimensions (number of thread blocks total).

block: Dim3

Block dimensions (threads per block).

cluster: ClusterDim

Cluster dimensions (blocks per cluster).

shared_mem_bytes: u32

Dynamic shared memory per block in bytes.

Implementations

impl ClusterLaunchParams

pub fn blocks_per_cluster(&self) -> u32

Returns the total number of blocks per cluster.

pub fn cluster_count(&self) -> CudaResult<u32>

Returns the total number of clusters in the grid.

This requires that the grid dimensions be evenly divisible by the cluster dimensions.

Errors

Returns CudaError::InvalidValue if the grid is not evenly divisible by the cluster dimensions, or if any dimension is zero.

pub fn validate(&self) -> CudaResult<()>

Validates the cluster launch parameters.

Checks that:

• All grid, block, and cluster dimensions are non-zero.
• The grid dimensions are evenly divisible by the cluster dimensions.

Errors

Returns CudaError::InvalidValue on any violation.
