LOCK-FREE UNORDERED IN-PLACE COMPACTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18468642 titled 'LOCK-FREE UNORDERED IN-PLACE COMPACTION
Simplified Explanation
The abstract describes techniques for lock-free, unordered in-place compaction of an array, involving generating a new array with valid and invalid data entries from an original array and replacing invalid entries with valid ones.
- Techniques for lock-free, unordered in-place compaction of an array:
* Receiving a first array with data entries * Generating a second array with valid and invalid data entries * Storing index positions of valid and invalid entries in the second array * Determining invalid entries in the first portion of the first array * Determining valid entries in the second portion of the first array * Replacing invalid entries with valid entries in the first array
Potential Applications
The technology could be applied in database management systems, file systems, and memory management systems.
Problems Solved
This technology solves the problem of efficiently compacting arrays without locks, allowing for better memory management and performance.
Benefits
- Improved memory usage
- Enhanced performance
- Simplified array compaction process
Potential Commercial Applications
"Efficient Array Compaction Techniques for Improved Performance and Memory Management"
Possible Prior Art
There may be prior art related to array compaction techniques in database systems or memory management systems.

Original Abstract Submitted
Various embodiments include techniques for lock-free, unordered in-place compaction of an array. The techniques include receiving a first array that includes a first plurality of data entries, generating a second array that includes a second plurality of data entries, and storing, in the second array, respective index positions of valid data entries included in the first array and invalid data entries included in the first array. The techniques further include determining invalid data entries included in a first portion of the first array based at least on the index positions, determining valid data entries included in a second portion of the first array based at least on the index positions, and replacing contents of the invalid data entries included in the first portion of the first array with contents of the valid data entries included in the second portion of the first array.
