We describe an algorithm that achieves garbage collection when performing concurrent rewriting. We show how this algorithm follows the implementation model of concurrent graph rewriting. This model has been studied and directly implemented on MIMD machines where nodes of the graph are distributed over a set of processors. A distinguishing feature of our algorithm is that it collects garbage con...

This paper describes the design and the evaluation of Complementary Garbage Collector that is a fundamental algorithm for the parallel and incremental garbage collector. Our algorithm is a combination of two types of fundamental algorithms, incremental update and snapshot-at-beginning, which are complementary to each other. The algorithm has the advantages of both types: great e ciency of the g...

Many of the current software systems rely on garbage collectors for automatic memory management. This is also the case for various software systems in real-time applications. However, a real-time application often requires an incremental working style of the underlying garbage collection, which renders the garbage collector more complex and less trustworthy. We present a formal verification of ...

1. Introduction Traditional batch garbage collection techniques lead to long delays in the programming execution. Different methods to reduce the delays have been suggested. These methods can be divided into two classes: those intended to give acceptable pauses in interactive programs (programs that interact with a user), and those intended for real-time programs. In an interactive program, it ...

800x600   introduction:  many items are needed for dressing including sterile dressing set, antiseptic and washing solutions, leucoplast tape, waste bin for infectious garbage, waste bin for noninfectious garbage, safe disposal trash for sharp cutting instruments, bedpan and sometimes drugs. all the items are laid out on a simple wheeled trolley. the multiplicity of items together with problems...

We present a new algorithm for garbage collection of the term stack in David H. D. Warren's abstract Prolog machine (WAM). The algorithm exploits the possibilities of using a large address space, with special attention paid to virtual memory behaviour. The time required for the algorithm depends linearly on the size of the areas in which garbage is collected. Pseudo-code is given for the whole ...

Garbage collectors perform two functions: live-object detection and dead-object reclamation. In this paper, we present a new technique for live-object detection based on run-time type reconstruction for a strongly-typed, polymorphic language. This scheme uses compile-time type information together with the run-time tree of activation frames to determine the exact type of every object participat...

C Project Description Programming languages that rely on garbage collection are becoming ubiquitous. Java and C# are especially popular. Both languages provide numerous software engineering advantages over languages like C and C++. The advantages of garbage collection include safety from accidental memory overwrites, protection from security violations, and the automatic prevention of space lea...

The complexity of systems for automatic control and other safety-critical applications grows rapidly. Computer software represents an increasing part of the complexity. As larger systems are developed, we need to find scalable techniques to manage the complexity in order to guarantee high product quality. Memory management is a key quality factor for these systems. Automatic memory management, ...
