class cuda.bindings._v2.driver.GraphChildGraphNodeOwnership(value: int)

Child graph node ownership

See CUgraphChildGraphNodeOwnership.

CLONE: 0

Default behavior for a child graph node. Child graph is cloned into the parent and memory allocation/free nodes can’t be present in the child graph.

MOVE: 1

The child graph is moved to the parent. The handle to the child graph is owned by the parent and will be destroyed when the parent is destroyed. The following restrictions apply to child graphs after they have been moved: Cannot be independently instantiated or destroyed; Cannot be added as a child graph of a separate parent graph; Cannot be used as an argument to cuGraphExecUpdate; Cannot have additional memory allocation or free nodes added.

INVALID: -1

Invalid ownership flag. Set when params are queried to prevent accidentally reusing the driver-owned graph object
