Struct DeviceContext

Source

pub struct DeviceContext {
    pub device: DeviceSpec,
    pub device_handle: Arc<Device>,
    pub signal: Arc<dyn TimelineSignal>,
    pub timeline: AtomicU64,
    pub allocator: Arc<dyn Allocator>,
}

Expand description

Per-device execution context.

Each device has its own timeline signal, queue, and allocator. This enables parallel execution across devices with proper synchronization.

Fields§

§device: DeviceSpec

Device specification (CPU, CUDA:0, etc.).

§device_handle: Arc<Device>

Device abstraction for rendering/compiling/executing.

§signal: Arc<dyn TimelineSignal>

Timeline signal for this device’s operations.

§timeline: AtomicU64

Current timeline value (monotonically increasing).

§allocator: Arc<dyn Allocator>

Allocator for this device.

Implementations§

Source §

impl DeviceContext

Source

pub fn signal_completion(&self, value: u64)

Signal that operations up to the given timeline value are complete.

Source
