Topic: Garbage collection (computer science)



  
 Garbage collection (computer science) - Wikipedia, the free encyclopedia
Garbage collection was invented by John McCarthy around 1959 to solve the problems of manual memory management in his recently devised Lisp programming language.
In contrast to tracing garbage collection, reference counting is a form of automatic memory management where each object has a count of the number of references to it, and the object's memory is reclaimed when the count reaches zero.
In computer science, garbage collection (also known as GC) is a form of automatic memory management.

 Talk:Garbage collection (computer science) - Wikipedia, the free encyclopedia
Being garbage collected is a property of an implementation of a language.
VM paging, time-slicing), the time taken by a collection cycle is a typically a linear function of 1) the number of live objects, 2) the number of bytes of live objects, 3) the number of pointers in live objects, and 4) the number of dead objects.
Certainly, most languages that use garbage collection (in fact, all other than those that can be conservatively collected through third-party tools) have no explicit free operation, and this is part of the design of the language more than an implementation detail.

The algorithm proposed is an extension of a garbage collection algorithm proposed by Baker.
The algorithm which is proposed has the objective of differentiating the special case of garbage collection for objects with short lives.
The intuition is, that if a generation-based garbage collection scheme focuses its effort on scanning recently created objects, then its scanning efforts will pay off more in the form of more recovered garbage, than if it scanned older objects.

 Garbage Collection
Garbage collection thus reduces "the base problem of not having a handle on the useful life of your objects" from a global one to a local one.
In a non-garbage collected language, in addition to determining doing this, each module must be aware of whether any other (including those which haven't been written yet) also accesses the object, and if not free it.
In a garbage collected language, it's the responsibility of each module to maintain It's data structures and arrange for them to only contain those objects which that module needs.

She is particularly interested in topics in the systems area of computer science, specifically parallel and distributed systems and programming languages.
Garbage collection was once the domain of “unconventional” programming languages such as Lisp and SmallTalk, while programmers working in mainstream languages managed their own memory.
Current garbage collectors employ a number of assumptions about the the way data is used that may not be true for programs written in an imperative style, particularly those programs that make heavy use of arrays and thus do not use pointers to provide indirection.

 Computer Science 68, Notes 02-20
All we need is an algorithm to compute the objects reachable from the root set.
Whenever a new pointer is created to an object, the object's reference count is incremented, whenever a pointer is removed, the object's reference count is decremented.
By contrast, a simple mark-sweep or copying collector adds no direct overhead to "y = z;" and "x = z;", since information about object liveness is only computed during the garbage collection process, and is not maintained in between collections.

With the continued growth of distributed systems as a means to provide shared data, designers are turning their attention to garbage collection, prompted by the complexity of memory management and the desire for transparent object management.
This thesis presents a new algorithm for distributed garbage collection and describes its implementation in the Network Objects system.
Partial tracing of the distributed graph involves only objects thought to be part of a garbage cycle: no collaboration with other processes is required.

Garbage collecting, libraries are even available for such uncooperative languages as C and C++.
The efficiency and correctness of garbage collection algorithms is henceforth going to be of concern to hundreds of thousands of programmers; those who really care about this could do no better than to start with Garbage Collection: Algorithms for Automatic Dynamic Memory Management...
And yet the answer is relatively easy - garbage collection; removing the clutter of memory management from module interfaces, which then frees the programmer to concentrate on the problem at hand rather than low-level book-keeping details.

In this talk, we present two new garbage collection algorithms that exploit object lifetime and pointer updates behavior in new ways to improve performance and pause times.
The increasing reliance on garbage collected languages requires high performance from the memory management system.
A hybrid collector then combines copying generational collection on the young objects and ulterior reference counting on the old objects to combine good throughput and low pause times.

 math lessons - Persistent data structure
In computing, a persistent data structure is a data structure which always preserves the previous version of itself when it is modified; such data structures are effectively immutable, as their operations do not (visibly) update the structure in-place, but instead always yield a new updated structure.
A better method is to exploit the similarity between the new and old versions to share structure between them, such as using the same subtree in a number of tree structures.
However, because it rapidly becomes infeasible to determine how many previous versions share which parts of the structure, and because it is often desirable to discard old versions, this necessitates an environment with garbage collection.
