A system, method, and computer program product are provided for efficiently performing a scan operation. In use, an array of elements is traversed by utilizing a parallel processor architecture. Such parallel processor architecture includes a plurality of processors each capable of physically executing a predetermined number of threads in parallel. For efficiency purposes, the predetermined number of threads of at least one of the processors may be executed to perform a scan operation involving a number of the elements that is a function (e.g. multiple, etc.) of the predetermined number of threads.

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.

A graphics processing unit calculates transformation matrices for changes to the position and orientation of objects. The graphics processing unit applies the transformation matrices to vertices of objects to be rendered.

A graphics system supports arrays of cube map textures. In one implementation, a cube map texture is utilized as an index into a set of cube map textures. The set of cube map textures may further be arranged into an atlas of two-dimensional textures.
