Parallelized Graphics State Validation for GPU Idle Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional client-server architecture between a CPU and GPU leads to inefficiencies due to synchronous APIs, where the client must wait for GPU server responses, causing idle time on both sides and limiting parallel processing.
Innovation Solution
Implementing a parallelized scripting environment that allows setting and validating graphics states without waiting for GPU completion, enabling simultaneous and asynchronous processing of graphics states and draw tasks, with optional debug mode for serial validation and error checking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronous APIs are used in client-server architecture, then error checking and validation can be performed sequentially, but the client must block until GPU server responses are available, causing idle time
Solution Approach 1:
The system performs preliminary validation of graphics states before submitting draw tasks to the GPU. By validating states in advance and caching validation results, the system ensures reliability without blocking the client thread during actual rendering operations. This allows the client to continue processing frames without waiting for GPU validation responses.
Solution Approach 2:
The patent introduces an intermediary validation mechanism that separates the client's graphics state setting operations from the GPU's execution. The validation layer acts as a mediator that pre-checks state validity and provides results asynchronously, allowing the client to proceed without synchronous blocking while maintaining error detection capabilities.
2Manufacturing precision
If the client waits for GPU completion before setting next graphics state, then validation can be performed sequentially, but the client and server spend significant time idle waiting
Solution Approach 1:
Graphics states are validated in advance before being submitted to the GPU for execution. The validation process is performed asynchronously and cached, allowing the client to set multiple graphics states in parallel without waiting for GPU completion. This maintains validation accuracy while significantly improving processing throughput by eliminating idle waiting time.
Solution Approach 2:
The system enables continuous graphics state setting and validation operations without interruption for GPU completion waits. By decoupling the validation process from GPU execution timing, the client can continuously prepare and validate graphics states in parallel, maintaining productive action flow throughout the rendering pipeline.
3Productivity
If asynchronous graphics state setting is implemented, then parallel processing can occur, but error checking and reporting become more complex
Solution Approach 1:
Error checking is performed as a preliminary action on graphics states before they are submitted to the GPU. By validating states in advance and caching validation results, the system simplifies asynchronous error handling. The client can proceed with parallel processing while maintaining straightforward error detection through pre-computed validation states.
4Reliability
If validation failure is reported to the client, then errors can be addressed, but the draw task associated with the invalid graphics state must be skipped
Solution Approach 1:
Validation failures are detected in advance through preliminary validation of graphics states. By performing validation before task submission and caching results, the system can efficiently skip only the specific draw tasks associated with invalid states while maintaining productivity. The preliminary validation approach allows targeted error handling without disrupting overall processing flow.

AI summary
Various content may be defined and display in parallel in a scripting environment. The scripting language may not wait for error checking or reporting before proceeding to updating the content definition. In one embodiment, no error checking or reporting may be performed. Content may be defined by setting graphics states while content may be displayed by validating the graphics states and submitting validated states to a GPU. The defining and display of content may be performed asynchronously.
