Engineering Contradiction Analysis
1Productivity
If communication occurs between cores distributed in different computers through network cards, then parallel computing capability is improved, but communication performance deteriorates due to bandwidth and latency limitations
Solution Approach 1:
The patent segments the network into two distinct parts: a high-performance computing network for inter-thread communication and a management network for general communication. This segmentation allows each network to be optimized for its specific purpose, with the computing network using ring/daisy-chain topology and high-speed network cards dedicated to parallel computing tasks, thereby resolving the contradiction between parallel computing capability and communication performance.
Solution Approach 2:
The patent introduces high-speed network cards with InfiniBand protocol as intermediaries between computational cores. These specialized network cards act as mediators that enable high-speed communication between distributed cores, overcoming the limitations of standard network cards and maintaining communication performance while enabling parallel computing across multiple computers.
2Ease of manufacture
If standard network cards are used for inter-computer communication, then system cost is reduced, but communication latency increases
Solution Approach 1:
The patent changes the key parameter of network card performance by specifying high-speed network cards with InfiniBand protocol for the computing network, while using standard network cards for the management network. This parameter differentiation allows the system to achieve low communication latency where needed (in inter-thread communication) while controlling costs in less critical areas (management communication).
3Productivity
If computational domain is divided into many partitions for parallel processing, then computing speed is improved, but communication overhead increases due to data consistency requirements
Solution Approach 1:
The patent applies local quality by creating a specialized high-performance communication environment specifically for inter-thread communication tasks. The ring/daisy-chain topology and high-speed network cards provide localized optimization for data exchange at partition interfaces, reducing communication overhead and energy loss while maintaining the benefits of fine-grained parallel processing across many partitions.
