Field Documentation
◆ from_port
| unsigned char hipGraphEdgeData::from_port |
This indicates when the dependency is triggered from the upstream node on the edge. The meaning is specfic to the node type. A value of 0 in all cases means full completion of the upstream node, with memory visibility to the downstream node or portion thereof (indicated by to_port). Only kernel nodes define non-zero ports. A kernel node can use the following output port types: hipGraphKernelNodePortDefault, hipGraphKernelNodePortProgrammatic, or hipGraphKernelNodePortLaunchCompletion.
◆ reserved
| unsigned char hipGraphEdgeData::reserved[5] |
These bytes are unused and must be zeroed.
◆ to_port
| unsigned char hipGraphEdgeData::to_port |
Currently no node types define non-zero ports. This field must be set to zero.
◆ type
| unsigned char hipGraphEdgeData::type |
This should be populated with a value from hipGraphDependencyType.
