Struct MultiDeviceCooperativeLaunchConfig 

pub struct MultiDeviceCooperativeLaunchConfig {
    pub per_device: Vec<DeviceLaunchConfig>,
}

Configuration for a multi-device cooperative kernel launch.

Wraps a collection of DeviceLaunchConfig entries, one per participating device. All entries must use the same grid and block dimensions.

Fields

per_device: Vec<DeviceLaunchConfig>

Per-device configurations.

Implementations

impl MultiDeviceCooperativeLaunchConfig

pub fn new(per_device: Vec<DeviceLaunchConfig>) -> CudaResult<Self>

Errors

Returns CudaError::InvalidValue if:

• The list is empty.
• Grid or block dimensions differ across devices.
• Any device ordinal is negative.
• Any dimension component is zero.

pub fn device_count(&self) -> usize

Number of devices participating in the launch.
