摘要： A method and apparatus for distributing the workload of rendering an image where texture mapping is involved among multiple graphics processing units (GPUs) are provided. The method generally entails dividing a texture map among multiple GPUs, performing texture mapping in each GPU to render image data in each GPU's frame buffer, combining the image data from each frame buffer, and scanning out the combined image to a display.

摘要： One embodiment of the present invention sets forth a set of application programming interface (API) extensions that enable a software application to control the processing work assigned to each GPU in a multi-GPU system. The software application enumerates a list of available GPUs, sets an affinity mask from the enumerated list of GPUs and generates an affinity device context associated with the affinity mask. The software application can then generate and utilize an affinity rendering context that directs rendering commands to a set of explicitly selected GPUs, thus allocating work among specifically selected GPUs. The software application is empowered to use domain specific knowledge to better optimize the work assigned to each GPU, thus achieving greater overall processing efficiency relative to the prior art techniques.

摘要： One embodiment of the present invention sets forth a technique for performing low latency computation on a parallel processing subsystem. A low latency functional node is exposed to an operating system. The low latency functional node and a generic functional node are configured to target the same underlying processor resource within the parallel processing subsystem. The operating system stores low latency tasks generated by a user application within a low latency command buffer associated with the low latency functional node. The parallel processing subsystem advantageously executes tasks from the low latency command buffer prior to completing execution of tasks in the generic command buffer, thereby reducing completion latency for the low latency tasks.

摘要： One embodiment of the present invention sets forth a technique for compositing a rendered path object into an image buffer. A shader program executing within a graphics processing unit (GPU) performs a stenciling operation for the path object and subsequently performs a texture barrier operation, which invalidates caches configured to store texture and frame buffer data within the GPU. The shader program then performs covering operation for the path object in which the shader renders color samples for the path object and composites the color samples into an image buffer. The shader program binds to the image buffer for access as both a texture map and a writeable image. Stencil values are reset when corresponding pixels are written once per path object, and texture caches are invalidated via the texture barrier operation, which is performed after each covering operation per path object.

摘要： A method for generating a texture buffer object configured for storing and manipulating texture data for graphics processing operations includes the steps of creating a buffer object configured to store the texture data, binding the buffer object to a texture buffer object, binding the texture buffer object to one of a plurality of texture targets included within a texture image unit, and binding a shader program to a processing unit within a graphics rendering pipeline. One advantage of the disclosed method is that, once a texture buffer object is bound as the target of a texture image unit, shader programs may read and/or write to the buffer object referenced by the texture buffer object, without having to rebind that texture buffer object.

摘要： One embodiment of the present invention sets forth a technique for performing a computer-implemented method that controls memory access operations. A stream of graphics commands includes at least one memory barrier command. Each memory barrier command in the stream of graphics command delays memory access operations scheduled for any command specified after the memory barrier command until all memory access operations scheduled for commands specified prior to the memory barrier command have completely executed.
