Why it matters

Multi-stream shapes GPU utilization. Understanding shapes optimization.

The architecture

Create streams.

Assign kernels to streams.

Sync only where needed.

Multi-stream concurrencyStream 1computeStream 2H2D transferStream 3D2H transferStreams enable H2D + compute + D2H overlap; pinned host memory required

How it works end to end

Pinned memory: enables async copies.

Priority: high-prio for critical path.

cudaEvent for cross-stream sync.
