A method of operating a data processing system, such as a graphics processing system, is disclosed. A set of plural execution threads performs an iterative data processing operation in which the number of execution threads that perform a respective data processing operation decreases from one iteration to the next. The iterative data processing operation is performed such that at least one execution thread of the set plural execution threads exits the iterative data processing operation when there is at least one iteration of the iterative data processing operation remaining in respect of which the execution thread will not perform a respective data processing operation. A barrier condition may be changed in response to the execution thread exiting the iterative data processing operation.

Data processing systems

A graphics processor comprising a rasteriser, a renderer, and a fragment dependency manager, and a method of operating a graphics processor. The fragment dependency manager is operable to maintain plural queues, where each queue corresponds to a respective set of plural sets of one or more sampling points that an array of sampling points is divided into, and wherein each queue entry is indicative of one or more fragments that when processed by the renderer will produce rendered fragment data for one or more of the sampling points of the set of one or more sampling points to which the queue corresponds.
