System, method, and computer program product for graphics processing unit (GPU) demand paging

摘要

A system, method, and computer program product are provided for GPU demand paging. In operation, input data is addressed in terms of a virtual address space. Additionally, the input data is organized into one or more pages of data. Further, the input data organized as the one or more pages of data is at least temporarily stored in a physical cache. In addition, access to the input data in the physical cache is facilitated.

主权项

1. A method, comprising:
addressing input data in terms of a virtual address space; organizing the input data into one or more pages of data; at least temporarily storing the input data organized as the one or more pages of data in a physical cache; facilitating access to the input data in the physical cache; analyzing one or more data buffers including at least one of textures, acceleration data structures, or geometry; determining which of the one or more buffers will reside in a GPU memory; and determining which of the one or more buffers will reside in a host memory and be demand paged into the GPU memory.
