Dynamic Thread Count Adjustment for Request Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to dynamically optimize the number of parallel threads for processing incoming requests based on the availability of processing resources, leading to inefficiencies such as idle resources and context switches.
Innovation Solution
A system and method that utilize a request dispatcher to dynamically determine the number of parallel threads based on the availability of processing resources, ensuring that threads are executed in parallel only when sufficient resources are available, thereby avoiding idle resources and context switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system always executes the maximum number of parallel threads for a request, then the processing throughput is maximized, but the processing resources become idle or require frequent context switches when resources are not available
Solution Approach 1:
The system dynamically adjusts the number of parallel threads based on real-time availability of processing resources. The request dispatcher monitors resource availability and determines the optimal degree of parallelism for each request, transitioning from static maximum parallelism to dynamic adaptive parallelism that matches actual resource capacity
Solution Approach 2:
The system changes the parameter of parallel thread count from a fixed maximum value to a variable value that depends on resource availability. The request dispatcher modifies the degree of parallelism parameter based on current system state, allowing the number of parallel threads to fluctuate between 1 and the maximum possible based on available resources
2Productivity
If the system dynamically adjusts the number of parallel threads based on resource availability, then resource utilization is optimized, but the system complexity increases due to additional monitoring and decision logic
Solution Approach 1:
The request dispatcher performs multiple functions: it receives requests, determines the degree of parallelism based on resource availability, and dispatches threads to processing resources. By consolidating these functions into a single component, the system avoids the complexity of separate monitoring and scheduling modules while achieving dynamic resource allocation
Solution Approach 2:
The system automatically monitors resource availability and makes decisions about thread dispatching without external intervention. The request dispatcher self-regulates the degree of parallelism based on real-time resource state, eliminating the need for complex external control mechanisms or manual configuration
3Reliability
If the system sequentially executes threads when resources are not available, then context switches are avoided, but the processing time increases due to reduced parallelism
Solution Approach 1:
The system executes the maximum number of parallel threads possible given current resource availability, rather than always executing the full maximum or always sequentially. This partial parallelism approach utilizes available resources fully while avoiding the penalties of both complete sequential execution and over-subscription

AI summary
Provided is a process for determining a number of parallel threads for a request. The process involves receiving availability data regarding processing resources, wherein the availability data indicates which processing resources are idle or are to become idle. Based on the availability data, a number of parallel threads for the request is determined.
