cuda.bindings._v2.driver.graph_add_dependencies_v2( intptr_t h_graph, from_, to, edge_data, size_t num_dependencies, )#

Adds dependency edges to a graph.

The number of dependencies to be added is defined by num_dependencies Elements in from and to at corresponding indices define a dependency. Each node in from and to must belong to h_graph. If num_dependencies is 0, elements in from and to will be ignored. Specifying an existing dependency will return an error.

Parameters:

h_graph (intptr_t) – Graph to which dependencies are added.
from (object) –
Array of nodes that provide the dependencies. It can be:
- an int as the pointer address to the array, or
- a Python sequence of ints (as pointer addresses).
to (object) –
Array of dependent nodes. It can be:
- an int as the pointer address to the array, or
- a Python sequence of ints (as pointer addresses).
edge_data (intptr_t) – Optional array of edge data. If NULL, default (zeroed) edge data is assumed.
num_dependencies (size_t) – Number of dependencies to be added.
