◆ hipGraphNodeGetEnabled()

hipError_t hipGraphNodeGetEnabled ( hipGraphExec_t  hGraphExec,
hipGraphNode_t  hNode,
unsigned int *  isEnabled 
)

Query whether a node in the given graphExec is enabled.

Sets isEnabled to 1 if hNode is enabled, or 0 if it is disabled.

The node is identified by the corresponding node in the non-executable graph, from which the executable graph was instantiated.

hNode must not have been removed from the original graph.

Note
Currently only kernel, memset and memcpy nodes are supported.
Parameters
[in]hGraphExec- The executable graph in which to set the specified node.
[in]hNode- Node from the graph from which graphExec was instantiated.
[out]isEnabled- Location to return the enabled status of the node.
Returns
hipSuccess, hipErrorInvalidValue

◆ hipGraphNodeSetEnabled()

hipError_t hipGraphNodeSetEnabled ( hipGraphExec_t  hGraphExec,
hipGraphNode_t  hNode,
unsigned int  isEnabled 
)

Enables or disables the specified node in the given graphExec.

Sets hNode to be either enabled or disabled. Disabled nodes are functionally equivalent to empty nodes until they are reenabled. Existing node parameters are not affected by disabling/enabling the node.

The node is identified by the corresponding hNode in the non-executable graph, from which the executable graph was instantiated.

hNode must not have been removed from the original graph.

Note
Currently only kernel, memset and memcpy nodes are supported.
Parameters
[in]hGraphExec- The executable graph in which to set the specified node.
[in]hNode- Node from the graph from which graphExec was instantiated.
[in]isEnabled- Node is enabled if != 0, otherwise the node is disabled.
Returns
hipSuccess, hipErrorInvalidValue,
