Web23 okt. 2009 · Classical mark-and-sweep is sometimes modified so that the sweep phase compacts the free space by "sliding" non-garbage objects. This is called "mark-sweep-compact". This is fairly complicated but: PRO - no pointer write overhead PRO - cyclic data is collected PRO - storage management concurrency bottlenecks can be easily avoided … Once the unreachable set has been determined, the garbage collector may simply release the unreachable objects and leave everything else as it is, or it may copy some or all of the reachable objects into a new area of memory, updating all references to those objects as needed. These are called "non-moving" and "moving" (or, alternatively, "non-compacting" and "compacting") garbage collectors, respectively.

Web3 mei 2015 · mark is called to mark memory location/object as in use.

WebG1 is planned as the long-term replacement for the Concurrent Mark-Sweep Collector (CMS). Comparing G1 with CMS reveals differences that make G1 a better solution. One difference is that G1 is a compacting collector. Also, G1 offers more predictable garbage collection pauses than the CMS collector, and allows users to specify desired pause … WebMark-Sweep-Compact algorithms solve the shortcomings of Mark and Sweep by moving all marked – and thus alive – objects to the beginning of the memory region. The downside of this approach is an increased GC pause duration as we need to copy all objects to a new place and to update all references to such objects.
