Mojo package

sync

GPU synchronization primitives package.

This package provides GPU synchronization operations including:

• barrier: Block-level synchronization barriers
• syncwarp: Warp-level synchronization
• mbarrier: Memory barrier operations (arrive/wait)
• named_barrier: Named barriers for flexible synchronization
• schedule_barrier: AMD instruction scheduling barriers
• Semaphore: Device-wide semaphore implementation
• cp_async_bulk: Bulk async copy synchronization

These primitives enable coordination of execution and memory operations across threads, warps, and blocks in GPU kernels.

Modules

• ​semaphore: This module provides a device-wide semaphore implementation for NVIDIA GPUs.
• ​sync: This module provides GPU synchronization primitives and barriers.
