Engineering Contradiction Analysis
1Productivity
If operators of dataflow programs are mapped to hardware resources of reconfigurable processors, then execution capability is provided, but execution efficiency deteriorates due to suboptimal resource allocation
Solution Approach 1:
The system implements feedback by analyzing actual execution data and inefficiency patterns from dataflow program runs, then using this information to generate optimized operator mappings and hardware resource allocations. The feedback loop continuously improves resource allocation based on observed performance metrics.
Solution Approach 2:
The system performs preliminary analysis of dataflow programs to identify potential inefficiencies before execution, and pre-generates optimized operator mappings and hardware configurations. This preliminary action prevents suboptimal resource allocation from occurring in the first place.
2Measurement precision
If comprehensive analysis of inefficiencies is performed, then execution inefficiencies are detected, but analysis time and computational overhead increase
Solution Approach 1:
The system extracts and focuses analysis only on the most significant inefficiency patterns and critical paths in dataflow programs, rather than performing exhaustive analysis of all possible operations. This selective extraction maintains high detection accuracy while reducing overall analysis time.
Solution Approach 2:
The system performs partial analysis by concentrating computational resources on identifying the most impactful inefficiencies rather than achieving complete coverage. This approach provides sufficient precision for optimization while avoiding excessive analysis time.

AI summary
In a method, in response to an interface a computer-implemented analysis assistant initiates a presentation of inefficiency results, determined an efficiency analyzer based on a mapping of a dataflow program to execute on hardware of a computing system. The assistant receives an inefficiency included among the inefficiency results and composes formatted inefficiency results comprising a presentation format of the inefficiency to assist a developer of the dataflow program to interpret the inefficiency. The analysis assistant outputs the formatted inefficiency results to an interface, which can comprise an interface to output the formatted inefficiency results for use by the developer to improve the dataflow program in association with the inefficiency. In implementations the presentation can comprise an interactive presentation with a developer of the dataflow program. A computer program product and a computing system can implement the method. The computing system can execute the assistant, and can include the interfaces.
