Systems, methods, and apparatuses relating to debugging a configurable spatial accelerator are described. In one embodiment, a processor includes a plurality of processing elements and an interconnect network between the plurality of processing elements to receive an input of a dataflow graph comprising a plurality of nodes, wherein the dataflow graph is to be overlaid into the interconnect network and the plurality of processing elements with each node represented as a dataflow operator in the plurality of processing elements, and the plurality of processing elements are to perform an operation by a respective, incoming operand set arriving at each of the dataflow operators of the plurality of processing elements. At least a first of the plurality of processing elements is to enter a halted state in response to being represented as a first of the plurality of dataflow operators.
