fz::CompressionDAG::FusedGroupExec Struct Reference

#include <dag.h>

Public Attributes
DAGNode *	head = nullptr
	first logical node on the fused main path
DAGNode *	tail = nullptr
	last node; its output = the archive
DAGNode *	dispatch = nullptr
	member whose schedule point launches the kernel
std::vector< DAGNode * >	members
	all group nodes (skipped individually)
std::vector< Stage * >	stages
	group stages for the runner context
const FusedImpl *	impl = nullptr
	matched fused implementation
std::string	execution_path
	last runtime path, when reported by runner
bool	executed = false
	reset between DAG executions

Detailed Description

A fusion group installed for execution: the fused runner replaces the member stages' individual execute()s with one call at the head node, writing the tail node's output buffer. See fusion_registry.h.
