摘要： A Resource Dependency Viewer for graphics processing unit (GPU) execution information is disclosed. The Resource Dependency Viewer provides profiling/debugging information concurrently with information about execution flow, resource utilization, execution statistics, and orphaned resources, among other things. A user-interactive graph (“dependency graph”) may be provided via a graphical user interface to allow interactive analysis of code executed on a GPU (e.g., graphics or compute code). Resource utilization and execution flow of encoders may be identified by analyzing contents of a GPU workload representative of a GPU execution trace to generate the dependency graph. Information about dependencies and execution statistics may be further analyzed using heuristics to identify potential problem areas. The dependency graph may include visual indicators of these problem areas. Results oriented navigation from the dependency graph and other visual panes provide debugging navigation techniques different than a debugging interface configured to “step” through code or provide static analysis.

摘要： Described is a system that processes texture assets for an application to be distributed across a range of devices while still leveraging device-specific hardware capabilities. In one embodiment, the system processes various criteria and determines specialized texture asset variants for a set of devices. These criteria may include various selected options including an interpretation selection for interpreting a source image for a texture, and device trait options such as device type, memory, and software support. In addition, the system may create mipmaps based on attributes of a set of target devices. Accordingly, a set of specialized texture assets may be created and distributed across a suite of devices.

摘要： Embodiments are directed toward systems and methods for scheduling resources of a graphics processing unit that determine, for a number of applications having commands to be issued to the GPU, a static priority level and a dynamic priority level of each application, work iteratively across static priority levels until a resource budget of the GPU is consumed, and starting with a highest static priority identify the applications in a present static priority level, assign a processing budget of the GPU to each of the applications in the present static priority level according to their dynamic priority levels, and admit to a queue commands from the applications in the present static priority level according to their processing budgets, and release the queue to the GPU.

摘要： An innovative GPU framework and related APIs present more accurate representations of the target hardware so that the distinctions between the fixed-function and programmable features of the GPU are perceived by a developer. This permits a program and/or a graphics object generated or manipulated by the program to be understood as not just code, but machine states that are associated with the code. When such an object is defined, the definitional components requiring programmable GPU features can be compiled only once and reused repeatedly as needed. Similarly, when a state change is made, the state changes correspond to the state changes made on the hardware. Additionally, the creation of these immutable objects prevents a developer from inadvertently changing portions of the program or object that cause it to behave differently than intended.
摘要翻译：创新的GPU框架和相关的API提供目标硬件的更准确的表示，以便GPU的固定功能和可编程功能之间的区别被开发人员所感知。这允许由程序生成或操纵的程序和/或图形对象被理解为不仅仅是代码，而是与代码相关联的机器状态。当定义这样的对象时，需要可编程GPU特征的定义组件只能编译一次，并根据需要重复使用。类似地，当进行状态改变时，状态改变对应于在硬件上进行的状态改变。另外，这些不可变对象的创建可以防止开发人员无意中更改程序或对象的部分内容，导致其行为与预期的不同。
