The method includes determining that a control flow graph representing a first section of a program includes at least two non-overlapping paths that extend from a first divergent node to a candidate node. The method also includes determining that the first divergent node is not a dominator of the candidate node or that the candidate node is not a post-dominator of the first divergent node. The method further includes identifying an external node and inserting a first instruction configured to cause a predicate variable to be set to true for a first set of threads that is to execute the external node. The method additionally includes inserting into the program a second divergent node configured to cause various threads to execute or not execute a first control flow path associated with the external node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Confluence analysis and loop fast-forwarding for improving SIMD execution efficiency","description":"One embodiment of the present invention sets forth a method for causing thread convergence.
