Colocated Nodes Constraint - Colocated Nodes Constraint - 2025.2 English - UG1079

The colocated nodes constraint requires two or more kernels to be on the same tile and forces sequencing of the kernels in a topological order. It also allows them to share memory buffers without synchronization.

Syntax

"colocated_nodes": [<node list>]
<node list> ::= <node name>[,<node name>...]
<node name> ::= string

Example

{
  "NodeConstraints": {
    "mygraph.k2": {
      "colocated_nodes": ["mygraph.k1"]
    }
  }
}
