pipeline.compose
← pipeline dialect
Compose a child pipeline into the enclosing invocation. Each composition constructs fresh child storage and independently progressing strands; it never submits another invocation. When the nearest schedule is pipeline.serial the child completes before that schedule advances. In a concurrent graph, composition adds no sibling dependency; the enclosing group owns its completion boundary. Specialization and run operands substitute the child's complete typed signature. Child target and materialization requirements remain binding.
