Abstract: Systems, apparatuses, and methods for implementing an auto generation and tuning tool for convolution kernels are disclosed. A processor executes multiple tuning runs of a given layer of a neural network while using a different set of operating parameter values for each tuning run. The operating parameters can include one or more of input dataset fetch group size, output channel group size, and other parameters. The processor captures performance data for each tuning run and then after all tuning runs have finished, the processor determines which set of operating parameter values resulted in a better performance for the given neural network layer. The processor uses these operating parameter values for subsequent iterations of the given layer. The processor also performs the same techniques for other layers to determine which set of operating parameter values to use for each layer so as to maximize performance of the neural network.

Abstract: Systems, apparatuses, and methods for efficient parallel execution of multiple work units in a processor by reducing a number of memory accesses are disclosed. A computing system includes a processor core with a parallel data architecture. One or more of a software application and firmware implement matrix operations and support the broadcast of shared data to multiple compute units of the processor core. The application creates thread groups by matching compute kernels of the application with data items, and grouping the resulting work units into thread groups. The application assigns the thread groups to compute units based on detecting shared data among the compute units. Rather than send multiple read access to a memory subsystem for the shared data, a single access request is generated. The single access request includes information to identify the multiple compute units for receiving the shared data when broadcasted.
