Solution Overview

Problem

Computing systems face degraded performance due to abnormal events like hardware or software failures, which require additional resources for diagnosis and recovery, leading to increased workload and potential SLA violations.

Innovation Solution

A resource management module detects abnormal events and dynamically adjusts processor settings to increase computing resources, such as adding cores or altering frequencies, to enhance processing capacity and facilitate quicker recovery and workload completion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If computing resources are increased to handle abnormal events, then recovery speed improves, but system complexity increases

Engineering Contradiction:

Improverecovery speedVSAvoidsystem complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The system dynamically adjusts processor settings based on operational conditions. When abnormal events are detected, the resource management module modifies processor frequencies and activates additional cores temporarily. This dynamic adjustment allows the system to have high recovery capacity when needed while maintaining low complexity during normal operation, resolving the contradiction between recovery speed and system complexity.

Inventive Principle:

Principle #15Dynamics

2Productivity

If processor frequency is increased to complete abnormal event processing, then processing capacity improves, but energy consumption increases

Engineering Contradiction:

Improveprocessing capacityVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic monitoring to detect abnormal events and applies processor frequency adjustments only during these specific periods when abnormal events occur. During normal operation, processors run at standard frequencies with normal energy consumption. This periodic intervention approach allows high processing capacity during abnormal events while maintaining acceptable energy consumption during normal operation.

Inventive Principle:

Principle #19Periodic action

3Reliability

If computing resources are allocated to handle abnormal events, then service level agreement compliance improves, but resource availability for other partitions decreases

Engineering Contradiction:

ImproveSLA complianceVSAvoidresource availability

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The resource management module applies computing resources locally and selectively to specific partitions experiencing abnormal events. Instead of globally reducing resources across all partitions, the system identifies the affected partition and allocates additional processor capacity specifically to that partition. This localized approach ensures SLA compliance for the affected partition while minimizing impact on resource availability for other partitions.

Inventive Principle:

Principle #3Local quality
