Bi-directional Communication in Parallel Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parallel processing systems suffer from limited communication capabilities, allowing only uni-directional communication between controllers and parallel processors, restricting the ability of processors to request additional resources or information, which hampers efficient processing due to assumptions about configuration that may not align with actual conditions.
Innovation Solution
Implementing bi-directional communication between controllers and units of execution, enabling processors to request resources, information, and perform operations, such as requesting additional memory or specialized hardware, thereby allowing dynamic resource allocation and configuration adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional parallel processing systems use uni-directional communication between controllers and parallel processors, then the system structure is simple and easy to implement, but the communication capability is limited and processors cannot request additional resources or information
Solution Approach 1:
The patent implements a feedback mechanism where parallel processors can send queries and receive answers from controllers, enabling bi-directional communication. This allows processors to request additional resources, information, or operations during parallel processing, transforming the traditional one-way instruction flow into an interactive communication system that adapts to actual processing needs.
2Adaptability or versatility
If parallel processors are allowed to send only results and errors to controllers, then the message exchange is simple and fast, but complex communications such as resource requests cannot be performed
Solution Approach 1:
The patent introduces dynamic message exchange capabilities where the type and content of messages between controllers and parallel processors are not fixed but can adapt based on processing requirements. Processors can dynamically generate queries for additional resources, information requests, or operational commands, and controllers can respond with appropriate answers, making the communication system flexible and responsive to changing processing needs.
3Productivity
If controllers assume a specific configuration on parallel processors, then the control logic is simplified, but processing efficiency decreases when configuration mismatches occur
Solution Approach 1:
The patent enables parallel processors to send queries to controllers to verify assumptions about system configuration, such as operating system type or available resources. This feedback mechanism allows processors to detect configuration mismatches and request appropriate adjustments or information, ensuring that processing continues efficiently even when initial assumptions about the environment are incorrect.
