Lazy compaction in garbage collection - A simplified explanation of the abstract
This abstract first appeared for US patent application 17967214 titled 'Lazy compaction in garbage collection
Simplified Explanation
The patent application describes techniques for lazy compaction, including selecting multiple regions of memory for relocation, populating a lazy free list (LFL) with these regions, and using load barriers to relocate live objects from the LFL.
- Garbage collector selects multiple memory regions for relocation
- Garbage collector populates a lazy free list (LFL) with selected regions
- Allocator determines when the ordinary free list is depleted
- Region in LFL is selected when ordinary free list is depleted
- Load barriers relocate live objects from the region
- Region is allocated after load barriers are executed
Potential Applications
- Memory management systems
- Garbage collection algorithms
- Resource optimization in software development
Problems Solved
- Efficient memory compaction
- Optimizing memory allocation
- Minimizing fragmentation in memory management
Benefits
- Improved memory usage
- Enhanced performance of memory-intensive applications
- Reduced overhead in memory management operations
Potential Commercial Applications
Optimizing Memory Management in Software Development
Possible Prior Art
No known prior art.

Original Abstract Submitted
Techniques for lazy compaction are disclosed, including: selecting, by a garbage collector, multiple regions of a memory for inclusion in a relocation set; populating, by the garbage collector, a lazy free list (LFL) with the multiple regions selected for inclusion in the relocation set; subsequent to populating the LFL: determining, by an allocator, that an ordinary free list managed by the garbage collector is depleted; responsive to determining that the ordinary free list is depleted: selecting a region in the LFL; executing one or more load barriers associated respectively with one or more objects marked as live in the region, each respective load barrier being configured to relocate the associated object from the region if the associated object is still live; subsequent to executing the one or more load barriers: allocating the region.
