Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed computing systems face inefficiencies in memory access management due to the limitations of uniform memory access (UMA) and non-uniform memory access (NUMA) models, which can lead to suboptimal performance and complexity in managing data sharing and communication between processors.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If UMA model is used, then memory access management is simplified, but system performance deteriorates due to memory access bottlenecks
Solution Approach 1:
The system dynamically switches between UMA and NUMA modes based on operational requirements. The memory access model is not fixed but adapts in real-time, allowing the system to optimize performance for different types of operations while maintaining simplified management when appropriate.
Solution Approach 2:
The invention changes the memory access parameter (from uniform to non-uniform) depending on the specific operation being executed. This allows the system to adjust the fundamental characteristics of memory access to match the requirements of different computational tasks.
2Productivity
If NUMA model is used, then memory access efficiency is improved, but device complexity increases due to data sharing management
Solution Approach 1:
The system uses NUMA mode dynamically and selectively rather than continuously. By switching to UMA mode when appropriate, the system reduces complexity for operations that don't require high-performance memory access, while still achieving optimal performance when NUMA is beneficial.
Solution Approach 2:
The invention applies different memory access strategies to different operations based on their specific requirements. Not all operations receive the same memory access treatment - instead, each operation gets the appropriate mode (UMA or NUMA) based on its characteristics.
3Stability of the object's composition
If fixed memory access mode is used, then system stability is improved, but adaptability to changing demands deteriorates
Solution Approach 1:
The system employs dynamic mode switching between UMA and NUMA based on real-time operational demands. This allows the system to maintain stability through consistent behavior patterns while simultaneously adapting to different performance requirements of various operations.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor operational characteristics and use this information to determine the appropriate memory access mode. This feedback loop enables the system to adapt to changing demands while maintaining stable and predictable operation.
