Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data center operations, determining the optimal number of computing systems for efficient distributed data processing is challenging, often resulting in either insufficient or excessive resources, leading to inefficiencies and increased costs due to power and hardware inefficiencies.
Innovation Solution
A data processing management system that monitors queue lengths and generates predictions based on processing time requirements, dynamically modifying the operational state of data processing systems to allocate the necessary resources, such as powering on or off systems, to match the workload demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If more computing systems are deployed to process data sets, then processing speed and efficiency are improved, but power consumption and hardware costs increase
Solution Approach 1:
The system dynamically adjusts the number of active computing systems based on real-time queue length monitoring and predictive algorithms. When queue length indicates high workload, additional systems are activated; when queue length is low, systems are deactivated or placed in sleep mode, creating a dynamic resource allocation that adapts to changing demands rather than maintaining a static configuration
Solution Approach 2:
The system uses predictive algorithms to forecast future queue lengths based on current trends and historical data. This allows the system to proactively activate or deactivate computing systems before the actual workload peaks or drops, ensuring optimal resource availability while avoiding unnecessary power consumption during low-demand periods
2Loss of energy
If fewer computing systems are used to reduce costs, then power and hardware efficiency are improved, but processing time requirements may not be met
Solution Approach 1:
The system continuously monitors queue length and processing status, using this feedback to adjust the number of active computing systems in real-time. This closed-loop control ensures that sufficient processing capacity is maintained to meet time requirements while minimizing energy waste, as the system responds to actual workload conditions rather than operating with fixed resource allocation
Solution Approach 2:
The system changes the operational parameters of computing systems by adjusting their power states (active, sleep, inactive) based on queue length thresholds and predictive forecasts. This parameter adjustment allows the system to optimize the balance between processing speed and energy consumption by matching system capacity to actual workload demands
3Reliability
If the number of computing systems is increased to ensure processing completion within required time, then reliability of meeting deadlines is improved, but operating costs increase
Solution Approach 1:
The system autonomously manages its own resource allocation by monitoring queue length and automatically activating or deactivating computing systems based on predictive algorithms. This self-service capability eliminates the need for manual system configuration and adjustment, reducing operational complexity while ensuring reliable deadline completion through automated, data-driven resource management

AI summary
To enhance the scaling of data processing systems in a computing environment, a number of data objects indicated in an allocation queue and a first attribute of the allocation queue are determined, where the allocation queue is accessible to a plurality of data processing systems. A number of data objects indicated in the allocation queue at a subsequent time is predicted based on the determined number of data objects and the first attribute. It is determined whether the active subset of the plurality of data processing systems satisfies a criterion for quantity adjustment based, at least in part, on the predicted number of data objects indicated in the allocation queue and a processing time goal. Based on determining that the active subset of data processing systems satisfies the criterion for quantity adjustment, a quantity of the active subset of data processing systems is adjusted.
