System B-Tree Work Coordination for Visible Cluster-Wide Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work coordination systems in operating systems are opaque and varied in operation, making it difficult to track, support, and diagnose processes such as work distribution, assignment, and execution across multiple systems.
Innovation Solution
A framework utilizing a lock domain and system B-tree (SBT) system for work coordination, enabling a single point of access through a controller to manage and observe work assignments from creation to completion, with features like exclusive locks, SBT generation numbers, and key/value pairs for efficient tracking and notification of work assignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple varied work coordination systems are used, then work distribution and execution can be performed across different systems, but tracking and diagnosing processes becomes difficult and complex
Solution Approach 1:
The patent merges multiple work coordination systems into a unified system using a single B-tree data structure that all work items share. Instead of maintaining separate coordination mechanisms for different work types, the invention combines them into one centralized B-tree structure with generation numbers that all entities can observe and interact with, thereby reducing overall system complexity while maintaining versatility
Solution Approach 2:
The B-tree data structure serves as a universal coordination mechanism that handles multiple work assignment types (new work, claim work, complete work, etc.) through a single interface. The generation number system provides a universal observation mechanism that all entities use to detect changes, eliminating the need for separate tracking systems for different work coordination functions
2Ease of manufacture
If opaque work coordination systems are used, then implementation flexibility is maintained, but observability and diagnostics of work processes are hindered
Solution Approach 1:
The patent uses generation numbers as visible indicators of B-tree state changes. Each time the B-tree is modified, the generation number increments, providing a clear, observable signal that entities can detect to determine when work assignments have been created, claimed, or completed. This makes the previously opaque coordination process transparent and easily diagnosable
Solution Approach 2:
The generation number system provides continuous feedback to all entities about the current state of the B-tree. By comparing their cached generation number with the current B-tree generation number, entities receive immediate feedback about whether the B-tree has changed, enabling them to detect and respond to work process events without needing to deeply understand the underlying implementation
3Measurement precision
If entities need deep knowledge of system implementation to monitor work assignments, then precise control is possible, but ease of operation decreases
Solution Approach 1:
The generation number acts as an intermediary that bridges entities and the B-tree state. Instead of requiring entities to directly examine complex B-tree structures or understand implementation details, they simply observe the generation number. This intermediary provides precise tracking capability while maintaining operational simplicity, as entities only need to compare generation numbers to detect changes
4Difficulty of detecting and measuring
If a unified work coordination system is implemented, then tracking and diagnostics are improved, but resource consumption increases
Solution Approach 1:
The patent implements partial observation where entities only check the generation number when needed, rather than continuously monitoring all B-tree contents. Entities cache the generation number and only perform comparisons when work assignment events are expected, reducing unnecessary computational resource consumption while maintaining full trackability of work processes
Data Source
AI summary
Technology described herein is related to work coordination through use of a system B-Tree system. An example method can comprise implementing, by a system comprising a processor, an exclusive lock in a lock domain that identifies a data structure representative of a system B-tree (SBT) of an SBT system, updating, by the system, an SBT generation number associated with the SBT, resulting in a first version of the SBT generation number, executing, by the system, in response to execution of a lock loss call back at the SBT, a comparison of the first version of the SBT generation number with a second version of the SBT generation number to determine a change of version of the SBT generation number, and identifying, by the system, a work assignment associated with the change of version of the SBT generation number.
