Systems, methods, and apparatuses relating to unstructured data flow in a configurable spatial accelerator are described. In one embodiment, a configurable spatial accelerator includes a data path having a first branch and a second branch, and the data path comprises at least one processing element; a switch circuit comprising a switch control input to receive a first switch control value to couple an input of the switch circuit to the first branch and a second switch control value to couple the input of the switch circuit to the second branch; a pick circuit comprising a pick control input to receive a first pick control value to couple an output of the pick circuit to the first branch and a second pick control value to couple the output of the pick circuit to a third branch of the data path; a predicate propagation processing element to output a first edge predicate value and a second edge predicate value based on (e.g., both of) a switch control value from the switch control input of the switch circuit and a first block predicate value; and a predicate merge processing element to output a pick control value to the pick control input of the pick circuit and a second block predicate value based on both of a third edge predicate value and one of the first edge predicate value or the second edge predicate value.
