Race Structure for Graphical Program Parallel Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Graphical programming environments, such as LabVIEW, face challenges in optimizing performance across multiple execution resources and algorithms, particularly in parallel execution scenarios, where determining the fastest resource or algorithm for a given task is unclear.
Innovation Solution
The implementation of a race structure in graphical programs, where multiple frames containing equivalent functionality execute in parallel, with the first to complete preempting others, allowing for dynamic optimization of performance by competing execution resources and algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple execution resources or algorithms are used for parallel execution, then productivity is improved, but device complexity increases
Solution Approach 1:
The program is divided into multiple frames (frame A, frame B, etc.), each containing a different execution resource or algorithm implementation. This segmentation allows parallel execution of multiple resources while maintaining clear structural organization, resolving the contradiction between improved productivity through parallelism and the complexity of managing multiple execution paths.
2Adaptability or versatility
If race structure with multiple frames is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The race structure implements dynamic selection among multiple frames at runtime. The system automatically determines which execution resource or algorithm completes first and uses that result, providing adaptability to different computational scenarios without requiring explicit optimization schemes. This dynamic behavior enhances versatility while the automated race mechanism manages the complexity of having multiple execution paths.

AI summary
System and method for executing a graphical program. A first structure in a graphical program is displayed on a display. The first structure includes two or more frames, each configured to contain a respective portion of the graphical program. The respective portions of the graphical program are included in the two or more frames. During execution of the graphical program, the first structure executes the respective portions of the graphical program in the two or more frames in parallel via respective execution processes. When a first portion of the respective portions completes execution prior to all others of the portions, execution of the other portions is terminated.
