In computer programming, resource management refers to techniques for managing resources (components with limited availability).. Computer programs may manage their own resources [which?] by using features exposed by programming languages (Elder, Jackson & Liblit (2008) is a survey article contrasting different approaches), or may elect to manage them by a host – an operating system or ...
Banker's algorithm is a resource allocation and deadlock avoidance algorithm developed by Edsger Dijkstra that tests for safety by simulating the allocation of predetermined maximum possible amounts of all resources, and then makes an "s-state" check to test for possible deadlock conditions for all other pending activities, before deciding whether allocation should be allowed to continue.
Resource acquisition is initialization (RAII) [1] is a programming idiom [2] used in several object-oriented, statically typed programming languages to describe a particular language behavior. In RAII, holding a resource is a class invariant , and is tied to object lifetime .
The problem often arises in resource allocation where the decision-makers have to choose from a set of non-divisible projects or tasks under a fixed budget or time constraint, respectively. The knapsack problem has been studied for more than a century, with early works dating as far back as 1897. [1]
The Stack Resource Policy (SRP) is a resource allocation policy used in real-time computing, used for accessing shared resources when using earliest deadline first scheduling. It was defined by T. P. Baker. [1] SRP is not the same as the Priority ceiling protocol which is for fixed priority tasks (FP).
Memory pooling is the use of a pool for memory management that allows dynamic memory allocation by preallocating a number of memory blocks with the same size called the memory pool, and is an alternative to dynamic memory allocation by techniques such as malloc and C++'s operator new which can suffer from fragmentation because of variable block ...
Resource allocation is the process by which a computing system aims to meet the hardware requirements of an application run by it. [1] Computing, networking and energy resources must be optimised taking into account hardware, performance and environmental restrictions. [ 2 ]
In Computer Science, Optimal Computing Budget Allocation (OCBA) is a simulation optimization method designed to maximize the Probability of Correct Selection (PCS) while minimizing computational costs. First introduced by Dr. Chun-Hung Chen in the mid-1990s, OCBA determines how many simulation runs (or how much computational time) or the number ...
