Game engine and method for providing an extension of the VSIPL++ API

摘要

A system includes a memory, a graphics processor, and a processor. The memory stores a control program that includes an extension of an application programming interface. The graphics processor includes multiple computational units. The processor executes the control program, with the control program causing the processor to obtain data from the memory. The data specifies a first function and is intended to execute on the multiple computational units. The control program further causes the processor to create at least one map for assigning computational tasks for the first function across the multiple computational units. A part of the data associated with each of the computational tasks is stored to the respective multiple computational units that are assigned to execute the computational tasks.
