Module ipc 

Inter-Process Communication for CUDA events and allocations.

Two producers / two consumers of cross-process state:

• Device memory: mem_get_handle → transmit bytes to another process → mem_open_handle gives you a device pointer aliasing the same physical memory. Close with mem_close_handle.
• Events: event_get_handle / event_open_handle for cross-process synchronization.

Availability: Linux only in practice. Windows drivers return CUDA_ERROR_NOT_SUPPORTED. Use external-memory / semaphore interop for Windows IPC.

Functions

event_get_handle

Export a CUDA event for sharing with another process.

event_open_handle

Open a peer-exported event handle. Returns a raw CUevent; wrap it with [Event::from_raw] if needed.

mem_close_handle

Release an imported device pointer previously opened via mem_open_handle.

mem_get_handle

Export a device allocation for sharing with another process.

mem_open_handle

Open a peer-exported device-memory handle. Returns a device pointer valid in the current context.
