Struct DeviceLaunchConfig 

pub struct DeviceLaunchConfig {
    pub device_ordinal: i32,
    pub function: CUfunction,
    pub grid_dim: (u32, u32, u32),
    pub block_dim: (u32, u32, u32),
    pub shared_mem_bytes: u32,
    pub stream: CUstream,
    pub args: Vec<*mut c_void>,
}

Per-device configuration for a multi-device cooperative launch.

Each entry describes one device’s contribution to the cooperative kernel. All entries in a multi-device launch must use identical grid and block dimensions.

Fields

device_ordinal: i32

Device ordinal (0-based).

function: CUfunction

Raw CUDA function handle for this device’s kernel.

grid_dim: (u32, u32, u32)

Grid dimensions (x, y, z) in blocks.

block_dim: (u32, u32, u32)

Block dimensions (x, y, z) in threads.

shared_mem_bytes: u32

Dynamic shared memory in bytes.

stream: CUstream

Stream handle for this device.

args: Vec<*mut c_void>

Kernel arguments (pointers to argument values).
