LOOP EXECUTION IN A RECONFIGURABLE COMPUTE FABRIC

Various examples are directed to systems and methods for performing operations in a reconfigurable compute fabric. A dispatch interface may send a first asynchronous message to a first flow controller of a first synchronous flow. The first asynchronous message may instruct the first flow controller to begin execution of a first-level loop. The first synchronous flow may send a second asynchronous message to a second flow controller of a second synchronous flow. The second asynchronous message may instruct the second flow controller to execute a second-level loop. The first flow controller may receive a third asynchronous message indicating that the second-level loop has completed and that a synchronous flow thread is free for executing a next iteration of the first-level loop.
