Scheduling algorithm

software errors and electro-magnetic effects. Therefore, fault-tolerance is an inherent requirement of systems when accurate results are needed even in the occurrence of faults. In the fault-tolerance area, redundancy is employed to mask or otherwise work around these faults, in this manner preserving a certain desired level of functionality. Generally, redundancy is defined as the deployment of spare resources (spatial) for the application. Permanent faults are generally tolerated by hardware redundancy, which is also known as modular redundancy (MR), where cloned tasks are running concurrently on multiple processing units. Broadly, three different techniques are used for implementing temporal redundancy based fault-tolerance in task scheduling: checkpointing, recovery block and recovery through…

The first is the prevention strategy which prevents deadlock from occurring at all by preventing one of the four conditions from coming to pass; most commonly it eliminates the circular waiting condition by making the processes adhere to some hierarchical order (Muhammad, 2011). The avoidance strategy attempts to anticipate when deadlock will happen by using algorithms that determine whether or not the CPU should allocate resources to processes or not, based on conditional statements; in short,…

Abstract— The P vs NP problem is still one of the greatest unsolved problem in Mathematics and computer Science. This survey paper is intended to explain what P vs NP problem is and what are the advances that have been made to solve this problem and How closer are we to solve this problem and what is its status i.e. Is P = NP? Keywords— Polynomial, Non - Determinsitic, P, NP, NPC Reductions, Reducibility, Reductions, certificate, complexity I. INTRODUCTION What is P vs NP? Why it is important to…

I became interested with an Information Security Analyst because my father is one. Every take your child to work day I would wake up early with my dad and run to his car excited to go to his office for the day. The building is a plain, brown brick building, but every time I saw it, I instantly got excited. Walking into the office everyone knew my name, I would always wave at everyone I saw. The secretary always gave me a lollipop and called me her “Little bundle of sunlight”. I would then go…

“It definitely sharpened my interest in language, the way people used language, slang words, speech patterns. There 's a big advantage to being the outsider” (1). This is a quote by Amy Heckerling, and it explains how speech patterns often go unnoticed by people of a certain group. A person with a southern accent believes that their accent is the normal, and a person with a Boston accent does not think they have one. Clive Thompson’s article “He and She; What’s the Real Difference?” explains an…

The ability to understand programming and all of its algorithms will grant anybody the power to keep up with technology. This is why elementary schools need computer science classes integrated into their curriculum. Teaching young children how to program will evolve the world in new ways by allowing these individuals to create new applications and technology. Since there are not any computer science related courses offered in elementary schools, they are restricted from the opportunity to learn…

In the article, “Grace Murray Hopper – Programming Pioneer”, author V. Rajaraman summarizes the life and accomplishments of Grace Murray Hopper, a woman who is credited for several major computer and technology developments. Rajaraman goes into extensive detail about Hopper’s early life, such as how Hopper focused heavily on her education in order to receive a PhD in Mathematics at Yale University which soon lead her to become a math professor at Vassar College. Rajaraman also mentions how…

paper is like designing the functionality and architecture of the code. Employing various ways to support an argument is like adapting known algorithms to suit specific purposes. And proofreading and revising a paper is like testing, debugging, and improving the code. Last summer at Cornell, I led weekly supplementary seminars for the Fundamental Programming Concepts course. Initially, I included many questions about the ins and outs of language-specific syntax and semantics in the worksheet.…
