Function cuGraphAddHostNode

pub unsafe extern "C" fn cuGraphAddHostNode(
    phGraphNode: *mut CUgraphNode,
    hGraph: CUgraph,
    dependencies: *const CUgraphNode,
    numDependencies: usize,

) -> CUresult

\brief Creates a host execution node and adds it to a graph

Creates a new CPU execution node and adds it to \p hGraph with \p numDependencies dependencies specified via \p dependencies and arguments specified in \p nodeParams. It is possible for \p numDependencies to be 0, in which case the node will be placed at the root of the graph. \p dependencies may not have any duplicate entries. A handle to the new node will be returned in \p phGraphNode.

When the graph is launched, the node will invoke the specified CPU function. Host nodes are not supported under MPS with pre-Volta GPUs.

\param phGraphNode - Returns newly created node \param hGraph - Graph to which to add the node \param dependencies - Dependencies of the node \param numDependencies - Number of dependencies \param nodeParams - Parameters for the host node
