The example techniques described in this disclosure may be directed to synchronization between producer shaders and consumer shaders. For example, a graphics processing unit (GPU) may execute a producer shader to produce graphics data. After the completion of the production of graphics data, the producer shader may store a value indicative of the amount of produced graphics data. The GPU may execute one or more consumer shaders, after the storage of the value indicative of the amount of produced graphics data, to consume the produced graphics data.
