Dynamic Resource Allocation Coordinator for Multi-Stage Processing Subsystems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dynamic workloads in multi-stage processing systems can lead to bottlenecks, causing performance issues as some processing stages experience sudden spikes in workload, resulting in delays and reduced overall system performance, especially when workload-level information is not available beforehand.
Innovation Solution
Implementing a dynamic resource allocation mechanism that assigns resources to processing stages on a task-by-task basis without prior knowledge of workload-level information, using a coordinator to dynamically assign resources from a general pool or dedicated sets based on properties such as data locality, bandwidth, and memory capacity, ensuring optimal resource utilization across stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static resource allocation is used in multi-stage processing systems, then device complexity is reduced and ease of operation is improved, but productivity deteriorates due to bottlenecks caused by sudden workload spikes
Solution Approach 1:
The patent implements dynamic resource allocation where the coordinator continuously monitors workload across processing stages and reallocates resources in real-time based on current conditions. This allows the system to adapt to sudden workload spikes and prevent bottlenecks, resolving the contradiction between maintaining simple static allocation and achieving high productivity under dynamic workloads.
Solution Approach 2:
The coordinator receives feedback from processing stages about their current workload and performance status, then uses this information to make informed resource allocation decisions. This feedback loop enables the system to automatically adjust resource distribution to maintain optimal throughput without requiring complex manual configuration.
2Productivity
If dynamic resource allocation is implemented to handle workload spikes, then productivity is improved, but device complexity increases due to the need for continuous monitoring and real-time reassignment mechanisms
Solution Approach 1:
The patent introduces a coordinator as an intermediary component that centralizes the complexity of dynamic resource allocation. The coordinator manages monitoring, decision-making, and resource reassignment, isolating the complexity from individual processing stages. This allows processing stages to remain relatively simple while still benefiting from dynamic resource allocation for improved throughput.
3Productivity
If resources are statically assigned to processing stages, then ease of operation is maintained and device complexity is low, but productivity suffers when workload distribution becomes uneven
Solution Approach 1:
The system enables self-service resource allocation where the coordinator automatically monitors workload conditions and reallocates resources without requiring manual intervention. This maintains ease of operation by eliminating the need for administrators to manually configure resources, while simultaneously improving productivity through automatic adaptation to changing workload conditions.
4Productivity
If a coordinator dynamically assigns resources from a general pool, then productivity is enhanced by reducing bottlenecks, but device complexity increases due to the coordination overhead
Solution Approach 1:
The coordinator is designed as a universal resource manager that handles multiple processing stages and various resource types through a single unified mechanism. This multi-functionality reduces overall system complexity by consolidating coordination logic in one component rather than requiring separate coordination mechanisms for each processing stage, while still achieving improved productivity through dynamic resource allocation.
