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.
