Multi-Mode GPU Profiling via Binary Instrumentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPU profiling systems are inefficient and resource-intensive, as they typically allow only single-mode profiling, require multiple runs to collect different types of profiling data, and incur significant overhead, making it difficult to analyze complex and computationally intensive GPU applications effectively.
Innovation Solution
A multi-mode profiling protocol that enables selection of instrumentation types on a per-shader or per-command basis, allowing for dynamic profiling configurations and reducing redundant compilation time by generating a single multi-mode instrumented binary code that can execute different profiling modes without recompiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If single-mode profiling is used, then profiling overhead is reduced, but multiple profiling runs are required to collect different types of data
Solution Approach 1:
The patent implements a multi-mode profiling system where a single instrumented binary code can execute multiple profiling modes (cycle counting, trace path analysis, data generation profiling) without requiring separate binaries or recompilation. The system uses mode selection mechanisms to activate different profiling instruments within the same codebase, allowing one profiling tool to serve multiple data collection purposes simultaneously.
Solution Approach 2:
The profiling system is divided into independent instrumentation modes that can be selectively activated. Each profiling mode (cycle counting, trace path, data generation) operates as a separate instrumentation layer within the unified binary, allowing the system to segment profiling functions while maintaining overall integration. This enables selective profiling of specific operations without affecting other profiling capabilities.
2Loss of information
If multiple profiling runs are executed, then comprehensive profiling data is collected, but compilation time and resource consumption increase
Solution Approach 1:
The system performs preliminary instrumentation of the binary code once to create a universal instrumented binary that contains all possible profiling modes. This preliminary action of instrumenting the code a single time with multiple profiling capabilities embedded eliminates the need for repeated compilation across multiple profiling runs, while still enabling collection of comprehensive profiling data through mode selection.
3Adaptability or versatility
If comprehensive instrumentation is applied, then all profiling modes can be executed, but execution overhead increases
Solution Approach 1:
The system implements comprehensive instrumentation with all profiling modes built into the binary, but only activates the necessary profiling modes for each specific profiling run. This partial execution approach ensures that while the binary contains all possible instrumentation (excessive preparation), only the required portion executes during each profiling operation, minimizing unnecessary overhead while maintaining full versatility when needed.
