Management Apparatus for Selective Device Activation in Information Processing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information processing systems, broadcasting activation requests to all devices can lead to redundant power consumption as all devices are activated, even if only a subset is needed for processing, resulting in inefficient power usage.
Innovation Solution
A management apparatus that broadcasts activation requests to information processing devices in a predetermined cycle, allowing only the specified number of devices to activate by issuing activation instructions and prohibiting others, thereby optimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If activation requests are broadcast to all information processing devices, then all devices can be activated to ensure sufficient processing capacity, but power consumption increases due to redundant activations
Solution Approach 1:
The system activates only the necessary number of devices (partial action) rather than all available devices. The management apparatus controls activation to match actual processing needs, avoiding excessive activation of unnecessary devices and reducing power consumption while maintaining sufficient processing capacity.
Solution Approach 2:
The system changes the activation state parameter of information processing devices from a static 'all or nothing' approach to a dynamic controlled state. By adjusting which devices are activated based on processing requirements, the system optimizes the balance between processing capacity and power consumption.
2Reliability
If all information processing devices are activated, then system reliability is improved through redundancy, but power consumption increases unnecessarily
Solution Approach 1:
Instead of activating all devices for redundancy, the system activates only the necessary number of devices to meet processing requirements. This partial activation approach maintains adequate system reliability while avoiding the excessive power consumption that would result from activating all available devices.
3Use of energy by moving object
If the management apparatus controls activation of each device individually, then power consumption is optimized, but system complexity increases
Solution Approach 1:
The management apparatus serves as an intermediary that centralizes activation control logic. By concentrating the decision-making process for device activation in a single management apparatus rather than distributing complex control logic across all devices, the system optimizes power consumption while avoiding excessive overall system complexity.

AI summary
A management apparatus includes a memory and a processor coupled to the memory. The processor is configured to broadcast an activation request to a plurality of information processing devices having a reception period during which the activation request is received. The reception period occurs in a predetermined cycle. The processor is configured to receive a confirmation response from first information processing devices among the plurality of information processing devices. The first information processing devices receive the activation request. The processor is configured to issue an activation instruction to a predetermined number of second information processing devices among the first information processing devices. The activation instruction instructs to activate the second information processing devices. The processor is configured to issue, to the first information processing devices other than the second information processing devices, an activation prohibition instruction to prohibit activation.
