Abstract
An apparatus and method for efficiently scheduling wavefronts for execution on an integrated circuit. In various implementations, a computing system includes a parallel data processing circuit with multiple, replicated compute circuits. Each compute circuit executes one or more wavefronts. Each compute circuit includes a cache configured to store temporary data that cannot fit in the vector general-purpose register file of the compute circuit. Each wavefront requests a corresponding amount of storage space in the cache for storing the temporary data. When the available data storage space in the cache is less than a data size requested by a wavefront waiting to be dispatched, a control circuit of the compute circuit reduces a dispatch rate of wavefronts. The control circuit also reduces an issue rate of instructions of one or more dispatched wavefronts to assigned execution circuits of the compute circuit.
