Struct MultiGpuContext 

pub struct MultiGpuContext { /* private fields */ }

Multi-GPU context for managing multiple devices

Implementations

impl MultiGpuContext

pub fn new() -> Result<Self>

Create a multi-GPU context by enumerating all available devices

pub fn device_count(&self) -> usize

Get number of available devices

pub fn device(&self, index: usize) -> Result<&Arc<Device>>

Get a device by index

pub fn active_device(&self) -> &Arc<Device>

Get the active device

pub fn active_device_index(&self) -> usize

Get the active device index

pub fn set_device(&mut self, index: usize) -> Result<()>

Set the active device

pub fn can_access_peer(&self, src: usize, dst: usize) -> Result<bool>

Check if peer access is enabled between two devices

pub fn enable_peer_access(&mut self, src: usize, dst: usize) -> Result<()>

Enable peer access between two devices

pub fn disable_peer_access(&mut self, src: usize, dst: usize) -> Result<()>

Disable peer access between two devices

pub fn all_properties(&self) -> Vec<&DeviceProperties>

Get properties for all devices

pub fn distribute_range(&self, total: usize) -> Vec<DeviceRange>

Distribute a 1D range across all devices (simple round-robin)
