Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtualization layer and virtual machines are introduced to manage parallel processing, then resource allocation and process management become more flexible, but processing overhead increases due to the additional software layers
Solution Approach 1:
The patent extracts and removes the virtualization layer and virtual machine software components from the parallel processing system. By eliminating these intermediate software layers, the system achieves direct hardware access for processes while maintaining resource allocation capabilities through hardware-based functional node groups, thereby reducing processing overhead while preserving adaptability.
2Productivity
If hardware is shared by multiple objects through time-sharing allocation, then resource utilization improves, but performance interference occurs between executing objects
Solution Approach 1:
The patent segments the parallel processing hardware into distinct functional node groups, where each group is dedicated to specific processes or applications. This segmentation allows multiple objects to utilize hardware resources simultaneously without time-sharing conflicts, as each functional node group operates independently with guaranteed communication bandwidth, eliminating performance interference while maintaining high resource utilization.
3Ease of operation
If virtual machines are used to isolate processes, then process separation is achieved, but the separation is imperfect due to shared hardware resources
Solution Approach 1:
The patent introduces functional node groups as hardware-based intermediaries between processes and physical hardware. These functional node groups act as dedicated communication channels that provide complete separation between processes, ensuring that each process operates within its own isolated hardware environment with guaranteed bandwidth, thereby achieving perfect separation without the imperfections of software-based virtualization.
4Adaptability or versatility
If communication bandwidth is not guaranteed for virtual machines, then system flexibility is maintained, but communication performance becomes unpredictable
Solution Approach 1:
The patent implements dynamic bandwidth allocation at the functional node group level, where communication bandwidth is guaranteed for each functional node group while allowing flexible resource distribution within groups. This dynamic approach ensures predictable communication performance between processes by dedicating hardware resources, while maintaining overall system flexibility through configurable functional node group assignments and bandwidth parameters.

AI summary
A parallel calculation system includes a plurality of functional nodes and a plurality of network switches, which serve as part of a communication path for communication between the functional nodes and function as communication channels. As for the functional nodes, a functional node group made up of part or all of a plurality of the functional nodes that the parallel calculation system includes is managed as one group. The network switches include a plurality of input/output ports, which are ports for inputting and outputting the communication request, and a switch, which outputs the communication request that the input/output port inputs to the input/output port. The network switches manage a communication bandwidth for each of the communication channels between the functional nodes and control the switch.
