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： Methods and systems for processing a geometry shader program developed in a high-level shading language are disclosed. Specifically, in one embodiment, after having received the geometry shader program configured to be executed by a first processing unit in a programmable execution environment, the high-level shading language instructions of the geometry shader program is converted into low-level programming language instructions. The low-level programming language instructions are then linked with the low-level programming language instructions of a domain-specific shader program, which is configured to be executed by a second processing unit also residing in the programmable execution environment. The linked instructions of the geometry shader program are directed to the first processing unit, and the linked instructions of the domain-specific shader program are directed to the second processing unit.

摘要： One embodiment of the invention is a method for storing transformed vertex attributes that includes the steps of allocating memory space for a transform feedback buffer, selecting one or more transformed vertex attributes to store in the transform feedback buffer independently of any shader programs executing on any processing units in the graphics rendering pipeline, configuring the transform feedback buffer to store the one or more transformed vertex attributes, and initiating a processing mode wherein vertex data is processed in the graphics rendering pipeline to produce the transformed vertices, the attributes of which are then written to the transform feedback buffer. One advantage is that the transform feedback buffer can be used to store and access transformed vertices, without having to convert the vertex data to a pixel format, store the pixels in a frame buffer, and then convert the pixels back to a vertex format.

摘要： One embodiment of the present invention sets forth a system configured for transferring data between independent application programming interface (API) contexts on one or more graphics processing units (GPUs). Each API context may derive from an arbitrary API. Data is pushed from one API context to another API context using a peer-to-peer buffer “blit” operation executed between buffers allocated in the source and target API context memory spaces. The source and target API context memory spaces may be located within the frame buffers of the source and target GPUs, respectively, or located within the frame buffer of a single GPU. The data transfers between the API contexts are synchronized using semaphore operator pairs inserted in push buffer commands that are executed by the one or more GPUs.

摘要： One embodiment of the invention is a method of accessing a bindable uniform variable bound to a buffer object that includes the steps of creating a linked program object comprising one or more shader programs, where each shader program includes instructions written in a high-level shader language, and where the linked program object includes a reference to a bindable uniform variable and indicates which shader programs use the bindable uniform variable. The method also includes determining a memory size to support the bindable uniform variable, allocating a buffer object having the memory size, binding the buffer object to the bindable uniform variable, populating the buffer object with values for the bindable uniform variable, and accessing the values of the bindable uniform with one or more of the shader programs in the linked program object.
