Solution Overview
Problem
Conventional shader compilers face challenges in efficiently selecting optimization passes within a short time frame, leading to poor shader performance and user frustration, as they lack an effective strategy for optimizing shaders during compilation.
Innovation Solution
A method and system that allow client devices to perform optimization procedures on shaders, compare results to best-known compilations, and communicate improved compilations back to a host system, which then broadcasts these optimizations to other devices for further refinement, using a network to facilitate efficient shader compilation and rendering.

Engineering Contradiction Analysis
1Loss of time
If conventional shader compilers perform optimization procedures within a short compilation time, then compilation speed is maintained, but shader optimization quality deteriorates
Solution Approach 1:
The system performs shader optimization in advance by distributing compilation tasks to multiple client devices before runtime execution. Each client device compiles shaders using different optimization strategies beforehand, and the best pre-compiled shader variants are stored for rapid selection during runtime, eliminating the need for time-consuming optimization during actual execution.
Solution Approach 2:
The optimization process is divided into multiple independent segments executed by different client devices. Each client device independently performs optimization passes on shader code using different strategies, and the results are compared to determine the best optimization. This segmentation allows parallel processing of optimization tasks across the network.
2Productivity
If shader compilers perform comprehensive optimization procedures, then shader execution performance improves, but compilation complexity increases
Solution Approach 1:
The system dynamically selects which optimization passes to apply based on the specific shader characteristics and target hardware. Different client devices are assigned different optimization strategies, and the system adapts by comparing results and selecting the most effective optimization sequence for each shader, rather than applying a fixed comprehensive optimization routine to all shaders.
Solution Approach 2:
The system varies optimization parameters such as the order and selection of optimization passes across different client devices. By changing these parameters and comparing the resulting shader compilations, the system identifies the optimal parameter configuration for each shader, achieving high execution performance without requiring all possible optimizations to be applied.
3Manufacturing precision
If multiple optimization passes are applied to shaders, then optimization quality improves, but power consumption increases
Solution Approach 1:
The system applies a selective subset of optimization passes to each shader based on the specific shader requirements and performance goals, rather than applying all possible optimization passes. Different client devices apply different subsets of optimizations, and the best results are selected, achieving high optimization quality while avoiding the excessive power consumption that would result from applying every possible optimization pass to every shader.

AI summary
Embodiments of the present invention are operable to communicate a list of important shaders and their current best-known compilations to remote client devices over a communications network. Client devices are allowed to produce modified shader compilations by varying optimizations. If a client device produces a modified compilation that beats an important shader's current best-known compilation, embodiments of the present invention can communicate this new best-known shader compilation back to a host computer system. Furthermore, embodiments of the present invention may periodically broadcast the new best-known shader compilation back to client devices for possible further optimization or for efficient rendering operations using the best-known shader compilation.
