Module sync 

Timeline synchronization primitives for parallel execution.

This module provides device-agnostic synchronization using timeline signals, which are monotonically increasing counters that enable ordering of operations across devices.

Design

Timeline signals abstract over:

• CPU: AtomicU64 with parking_lot condvar for waiting
• CUDA: Event pools keyed by timeline value
• Metal: MTLSharedEvent (future)
• HIP: Similar to CUDA (future)

Example

let signal = CpuTimelineSignal::new();

// Producer thread
signal.set(1);  // Signal completion of operation 1

// Consumer thread
signal.wait(1, 1000)?;  // Wait for operation 1 to complete

Structs

CpuTimelineSignal

CPU-based timeline signal using atomics and condvar.

Traits

TimelineSignal

Monotonic timeline signal for synchronization.
