Abstract: A method for graphics processing. The method including rendering graphics for an application using a plurality of graphics processing units (GPUs). The method including using the plurality of GPUs in collaboration to render an image frame including a plurality of pieces of geometry. The method including during a pre-pass phase of rendering, generating information at the GPUs regarding the plurality of pieces of geometry and their relation to a plurality of screen regions. The method including assigning the plurality of screen regions to the plurality of GPUs based on the information for purposes of rendering the plurality of pieces of geometry in a subsequent phase of rendering.

Abstract: Performance of a legacy application may be characterized for subsequent adjustment of operating parameters when running the legacy application on a new system. The legacy application is run on the legacy system and one or more key performance metrics that must be met when the legacy application is run on the new system are determined along with other performance information useful for later adjustment of operating parameters of the new system when running the legacy application on the new system.

Abstract: A method including rendering graphics for an application using graphics processing units (GPUs). The method including dividing responsibility for processing pieces of geometry of an image frame during an analysis pre-pass phase of rendering between the plurality of GPUs, wherein each of the pieces of geometry is assigned to a corresponding GPU. The method including determining in the analysis pre-pass phase overlap of each of the pieces of geometry with each screen regions. The method including generating information at the GPUs regarding the pieces of geometry and their relations to the screen regions based on the overlap of each of the pieces of geometry with each of the screen regions. The method including assigning the screen regions to the GPUs based on the information for purposes of rendering the pieces of geometry during a subsequent phase of rendering.

Abstract: A graphics processing may include implementing a vertex shader and a pixel shader with a GPU. Vertex parameter values generated by the vertex shader may be stored in a memory. The pixel shader may access the vertex parameter values stored in the memory. Accessing the vertex parameter values may include disabling or bypassing hardware that performs interpolation on vertex parameter values.

Abstract: Performance of a new system may be optimized to run a legacy application written for a legacy system. Performance information for the legacy application is recorded or derived while running the legacy application on the new system. Performance characteristics for the legacy application running on the new system are determined by analyzing the performance information. The performance characteristics include one or more key performance metrics and other performance information. The key performance metrics must be met when the legacy application is run on the new system. The other performance information is useful for adjusting one or more operating parameters of the new system when running the legacy application on the new system. The one or more operating parameters are adjusted so that the one or more key performance metrics are met.

Abstract: Graphics processing may include implementing a vertex shader and a pixel shader with the GPU. Vertex indices output from a vertex shader may be written to a cache. The vertex indices written to the cache may be accessed with the pixel shader and vertex parameter values associated with the vertex indices may be accessed from a memory unit with the pixel shader.

Abstract: A GPU is configured to read and process data produced by a compute shader via the one or more ring buffers and pass the resulting processed data to a vertex shader as input. The GPU is further configured to allow the compute shader and vertex shader to write through a cache. Each ring buffer is configured to synchronize the compute shader and the vertex shader to prevent processed data generated by the compute shader that is written to a particular ring buffer from being overwritten before the data is accessed by the vertex shader.

Abstract: To address problems that arise due to differences in bus behavior when running a legacy application on a new device the new device may throttle bus performance in a way that emulates the bus behavior of a legacy device when executing the legacy application.
