Data B. High-peripheral computing, 22: Peer-to-Peer leads to the development of  technologies like, A. C. Distributed application B. Peer-to-Peer E. All of these Grid computing is the use of widely distributed computer resources to reach a common goal. OpenMP threads management is based on the POSIX threads standard (Pthreads), which is defined as a set of interfaces (functions and header files) for threaded programming. Centralized computing The run-time framework takes care of the details of partitioning the input data, scheduling the program’s execution across a set of machines, handling machine failures, and managing the required intermachine communication. Mesos [16] enables multiple diverse computing frameworks such as Hadoop and Spark sharing a single system. Distributed vs. D. Both A and B A processing node is the host of processing elements (PEs) which perform data processing tasks on events. B. Moreover, the data are used to make decisions about user preferences. This methodology involves a shorter and more flexible development cycle than the same in the real system. The MapReduce framework was originally proposed by Google in 2004, since then, companies such as Amazon, IBM, Facebook, and Yahoo! Cause-addition operators allow for the explicit specification of causalities in algebraic expressions. G. None of these, 16: Resources and clients transparency that allows movement within a system is called, A.Mobility transparency D. Flexibility Total-order semantics are often confused with interleaving semantics. The achievement of this objective involves several factors such as understanding interconnection structures, technological factors, granularity, algorithms and policies of system. The most important aspect of simulation methodologies is to yield behaviour and results close to the real system. Rackspace currently hosts email for over 1 million users and thousands of companies on hundreds of servers. Minicomputers 1: Computer system of a parallel computer is capable of A. The Reduce function accepts an intermediate key (produced by the Map function) and a set of values for that key. In a total-order semantics, actions of a process are always totally ordered, whereas in a partial-order semantics, actions may occur simultaneously or causally independent of each other. Thus, a total-order semantics abstracts from the causal dependencies between actions. A. Adaptivity A… Each of these programming environments offers scope for benefiting domain-specific applications, but they all failed to address the requirement for general purpose software that can serve different hardware architectures in the way that, for example, Java code can run on very different ISA architectures. B. Parallel computing and distributed computing are two types of computation. B. S4 architecture is inspired by the MapReduce model. Therefore in this section, we look at the main features offered by the Apache Hadoop project for cluster infrastructure requirements. A branching-time semantics distinguishes processes with the same ordering of actions but different branching structures. In Section 9, the algebraic framework of Section 6 is extended with a class of so-called cause-addition operators. 15: Broader concept offers Cloud computing .to select which of the following. The fundamental idea of MRv2 is to split up the two major functionalities of the JobTracker into resource management and job scheduling. Yahoo! A process-algebraic theory with an expansion theorem is called an interleaving theory; the semantics of such an algebraic theory is called an interleaving semantics or an interleaving process algebra. Specific implementations of MPI exist, such as OpenMPI, MPICH and GridMPI [180]. Therefore, a trade-off solution between detail and complexity must be reached. F. None of these,  26: Even under failure conditions Providing Quality of Service (QoS) assurance is the responsibility of, A. Dependability 6 C. Centralized computing A computing grid can be thought of as a distributed system with non-interactive workloads that involve many files. Then an impact of the current computer software (object-oriented principles) and hardware (parallel and distributed computing) developments on integrating interconnected submodels is highlighted. This Hadoop cluster contains 15 nodes with three 500-GB disks each. Baeten, T. Basten, in Handbook of Process Algebra, 2001. E. All of these The main tool corresponds to an event-driven simulator that uses synthetic descriptions of a parallel programme and a parallel architecture. F. None of these. Grid computing Cloud organization is based on a large number of ideas and on the experience accumulated since the first electronic computer was used to solve computationally challenging problems. F. All of these Single system image: A client will see the same view regardless of the server to which it is connected. We use cookies to help provide and enhance our service and tailor content and ads. In a linear-time semantics, two processes that agree on the ordering of actions are considered equivalent. This class of operators is inspired by the way causalities are handled in Petri-net theory. The present project is the result of the evolution of a previous simulator (PSEE) developed upon a simple model. The adapter is responsible for the conversion of raw data into events before delivering the events into the S4 cluster. D. Distributed computing The chapter is written in the style of a tutorial. D. HTC The above discussion also makes clear that, for semantics of non-algebraic languages for describing concurrent systems, the characterization interleaving versus non-interleaving is not meaningful. Centralized computing Centralized memory E. All of these However, such processes may differ in their branching structure, where the branching structure of a process is determined by the moments that choices between alternative branches of behavior are made. Fig. S4 (Simple Scalable Stream Processing System) is a distributed real-time data processing system developed by Yahoo. a distributed computing system. E. All of these The HDFS is the primary distributed storage used by Hadoop applications. The resulting formalism is a step towards a framework supporting the development of complex concurrent systems. The resource manager and per-node slave manager (ie, node manager) form the data-computation framework. 5.2 shows a schema that illustrates the MapReduce main features and basic flow process. Hundreds of daily jobs are run performing operations such as log file analysis and chart generation. C. Parallel computing Business Gain the practical skills necessary to build Distributed Applications and Parallel Algorithms, focusing on Java based technologies. The components are rack-aware regarding network topology and storage model. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism. F. None of these. The chapter combines and extends some of the ideas and results that appeared earlier in [2,4], and [8, Chapter 3]. B. Cyber cycle S4 is capable of scaling to a large cluster size to handle frequent real-time data [11]. The Map/Reduce functions are as follows [167]: The Map function takes an input pair and produces a set of intermediate key/value pairs. 3: Simplifies application’s of three-tier architecture is ____________. As pointed out in [2], the term “interleaving” originates from one specific class of formal languages for describing concurrent systems, namely process algebras. According to Dean et al. In distributed computing, a single problem is divided into many parts, and each part is solved by different computers. Cyber Crime Solved MCQs Questions Answers. In addition to the basic R-Swoosh algorithm, the research group at InfoLab has also developed other algorithms intended to optimize ER performance in parallel and distributed system architectures. C. Tightly coupled A HDFS cluster consists of a name node that manages the file system metadata and data nodes that store the actual data [172]. The per-application master is in charge of negotiating resources from the resource manager and working with the node managers to execute the tasks [171]. Parallel processes A. E. All of these 18: Uniprocessor computing devices  is called__________. Master the theory of Distributed Systems, Distributed Computing and modern Software Architecture. As in Section 4, labeled transition systems form the basis for both a total-order and a partial-order framework. Parallel and Distributed Computing MCQs – Questions Answers Test” is the set of important MCQs. However, unlike MapReduce which has a limitation on scaling, Yahoo! A distributed cloud is an execution environment where application components are placed at appropriate geographically-dispersed locations chosen to meet the requirements of the application. The most important issues discussed in this manual are: The cluster requires exclusive machines for master services, NameNode and ResourceManager. 3 F. All of these Among them, we summarize the most significant case studies. Typically, just zero or one output value is produced per Reduce invocation. The semantics of a formal language for describing the behavior of concurrent systems defines a process for each expression in the formal language. First, there was the development of powerful microprocessors, later made even more powerful through multi-core central processing units (CPUs). Cloud computing is used to define a new class of computing that is based on network technology. –Clouds can be built with physical or virtualized resources over large data centers that are centralized or distributed. This company provides managed systems and email services for enterprises. An algebraic theory without an expansion theorem is said to be non-interleaving. Nowadays the theory, design, analysis, evaluation and application of parallel and distributed computing systems are still burgeoning, to suit the increasing requirements on high … 2C Distributed and Cloud Computing From Parallel Processing to the Internet of Things Kai Hwang Geoffrey C. Fox Jack J. Dongarra AMSTERDAM † BOSTON † HEIDELBERG † LONDON NEW YORK † OXFORD † PARIS † SAN DIEGO SAN FRANCISCO † SINGAPORE † SYDNEY † TOKYO Decentralized computing B. In other words, the MapReduce model arises as a reaction to the complexity of the parallel computing programming models, which consider the specific parallel factors involved in software development processes. The basic semantic equivalence that is used throughout the chapter is bisimilarity [51]. D. Business J.C.M. The idea is to have a global resource manager and per-application master. 5 types Partial-order semantics are often referred to as true-concurrency semantics, because they are well suited to express concurrency of actions. Two expressions in a formal language describe the same system if and only if they correspond to equivalent processes in the semantics, where the equivalence of processes is determined by a so-called semantic equivalence. IBM proposed the use of message-passing-based software in order to take advantage of its heterogeneous, non-coherent cell architecture and FPGA based solutions integrate libraries written in VHDL with C or C++ based programs to achieve the best of two environments. In Section 3, the basic semantic framework used throughout this chapter is defined. One discussion is centered around linear-time semantics versus branching-time semantics. Parallel computing F. None of these. D. Loosely coupled Distributed process The main goals and guarantees of ZooKeeper are summarized in [176] as follows: Sequential consistency: Updates will be applied in the order that they were sent. Decentralized computing Management B. The Hadoop documentation project offers a specific manual about Hadoop Cluster Setup [176]. C. Efficiency As long as the computers are networked, they can communicate with each other to solve the problem. B. Some of the topics covered in the first few sections of the chapter discuss the global state of a process group, communication protocols and coordination, logical clocks, message delivery rules, and causal history. In addition, we do not claim that the approach of this chapter is the only way to obtain a process-algebraic theory with a partial-order semantics. D. Both A and B Decentralized computing B. The programs using OpenMP are compiled into multithreading programs [163]. C. Parallel computing Quincy [68] is a fair scheduler for Dryad that achieves a fair scheduling of multiple jobs by formulating it as a min-cost flow problem. The remainder of this chapter is organized as follows. D. Both A and B C. Space-based In addition to the cluster infrastructure defined above, there is an additional project intended to enhance the cluster management services, namely, Apache ZooKeeper [176] enables highly reliable distributed coordination. E. All of these Along with the development of the large number of formal languages for describing concurrent systems, an almost equally large number of different semantics has been proposed. The existence of additional control services deployed in dedicated machines, Web App Proxy Server and MapReduce Job History Server. However, in [2], it is shown that it is possible to develop both process-algebraic theories with an interleaving, partial-order semantics and algebraic theories with a non-interleaving, total-order semantics. Adaptation E. All of these D. Tightly coupled With the aim of tackling this limitation, the Facebook team explored back-end data architectures and the role Hadoop can play in them. Distributed and Cloud Computing: From Parallel Processing to the Internet of Things offers complete coverage of modern distributed computing technology including clusters, the grid, service-oriented architecture, massively parallel processors, peer-to-peer networking, and cloud computing. Microcomputers B. Parallel and Distributed Computing MCQs – Questions Answers Test" is the set of important MCQs. F. All of these Another important theme of this chapter is the study of concepts known from Petri-net theory [53] in the process-algebraic framework developed in this chapter. C. Internet of things For example, in distributed computing processors usually have their own private or distributed memory, while processors in parallel computing can have access to the shared memory. Media mass E. All of these To obtain this goal, a careful model is necessary. As presented in Section 5.3.3, we can consider Hadoop in general terms as a framework, a software library, a MapReduce programming approach or a cluster management technology. Parallel and Distributed Computing MCQs – Questions Answers Test. Cloud computing is based on a large number of ideas and the experience accumulated since the first electronic computer was used to solve computationally challenging problems. As heterogeneous systems are becoming unavoidable, many of the major software and hardware manufacturers start creating software environments to support them.AMD proposed the use of the Brook language developed in Stanford University, to handle streaming computations, later extending the SW environment to include the Close to Metal (CTM)and the Compute Abstraction Layer (CAL) for accessing their low level streaming hardware primitives in order to take advantage of their highly threaded parallel architecture.
