Flexibility E. All of these This led to so-called parallelism where multiple processes could run at the same time. As in Section 4, labeled transition systems form the basis for both a total-order and a partial-order framework. The basic semantic equivalence that is used throughout the chapter is bisimilarity [51]. F. None of these, A. It provides a set of compiler directives to create threads, synchronize the operations, and manage the shared memory [177]. Parallel computing The user can analyse in a shorter and interactive way, the programme behaviour from the point of view of performance, estimating the influence of different parameters involved in the design. Developing software for homogeneous parallel and distributed systems is considered to be a non-trivial task, even though such development uses well-known paradigms and well established programming languages, developing methods, algorithms, debugging tools, etc. F. All of these Engineering Dan C. Marinescu, in Cloud Computing, 2013. One discussion is centered around linear-time semantics versus branching-time semantics. C. Efficiency NVIDIA took a similar approach, co-designing their recent generations of GPUs and the CUDA programming environment to take advantage of the highly threaded GPU environment. Furthermore, we show how to obtain a non-interleaving variant of such a process algebra. S4 architecture is inspired by the MapReduce model. The programs using OpenMP are compiled into multithreading programs [163]. D. Many Client machines The resource manager is the authority that arbitrates resources between all the applications in the system. The chapter is written in the style of a tutorial. E. All of these Finally, the chapter covers composability bounds and scalability. 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. These data need to be processed, stored, and allow the users to access them directly. F. None of these,  26: Even under failure conditions Providing Quality of Service (QoS) assurance is the responsibility of, A. Dependability Developing software to support general-purpose heterogeneous systems is relatively new and so less mature and much more difficult. 18: Uniprocessor computing devices  is called__________. The idea is to have a global resource manager and per-application master. In the case of Apache Hadoop there are custom services and cluster infrastructure solutions devoted to offering a comprehensive parallel processing framework for MapReduce applications. 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. In this section we review other parallel computing and programming frameworks. Atomicity: Updates either succeed or fail, that is, the system avoids partial results. HDFS supports large data-sets across multiple hosts to achieve parallel processing. In particular, it adopts the standard Petri-net mechanism for handling causalities.

The data stream within S4 is a sequence of events. B. The adapter is responsible for the conversion of raw data into events before delivering the events into the S4 cluster. There are various kinds of fair policies in the traditional HPC and grid computing, including round-robin [62], proportional resource sharing [63], weighted fair queuing [64], and max-min fairness [65]. As seen in the main conclusions presented in surveys of parallel programming models [180] and performance comparison studies [163], OpenMP is the best solution for shared memory systems, MPI is the convenient option for distributed memory systems, and MapReduce is recognized as the standard framework for big data processing. Grid computing is the use of widely distributed computer resources to reach a common goal. A processing node is the host of processing elements (PEs) which perform data processing tasks on events. Choosy [67] extends the max-min fairness by considering placement constraints. F. All of these C. Internet of things Single system image: A client will see the same view regardless of the server to which it is connected. E. All of these Parallel and Distributed Computing. In contrast, YARN [15] divides resources into containers (ie, a set of various resources like memory and CPU) and tries to guarantee fairness between queues. C. Centralized computing The relation between cause addition and sequential composition, which is the most important operator for specifying causal orderings in process algebra, is studied. D.

Fatos Xhafa, in Intelligent Data Analysis for e-Learning, 2017. A. In [119] the authors present a collection of Hadoop case studies contributed by members of the Apache Hadoop community. Therefore in this section, we look at the main features offered by the Apache Hadoop project for cluster infrastructure requirements. Although the Apache Hadoop project includes many Hadoop-related projects, the main modules are the Hadoop MapReduce and Hadoop distributed file system (HDFS) . If a node’s status is reported as unhealthy the node is blocked and no further tasks will be assigned to this node. Hadoop provides services for monitoring the cluster health and failover controls. 13: Data access and storage are elements of  Job throughput, of __________. Section 4 introduces a class of Petri nets called labeled P/T nets.

Parallel and distributed computing has offered the opportunity of solving a wide range of computationally intensive problems by increasing the computing power of sequential computers. Parallel computing provides concurrency and saves time and money. Moreover, the data are used to make decisions about user preferences. J.C.M. E. All of these B. The present project is the result of the evolution of a previous simulator (PSEE) developed upon a simple model. It is shown how labeled transition systems can be used to obtain both a total-order view of concurrent systems and a partial-order view, where the latter is based on the notion of step bisimilarity. A distributed system consists of more than one self directed computer that communicates through a network. E. All of these The framework of labeled transition systems is used to formalize the notion of a process and bisimilarity of processes.

Mainframe computers According to The Apache Software Foundation [176], ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. With the aim of tackling this limitation, the Facebook team explored back-end data architectures and the role Hadoop can play in them. The simultaneous growth in availability of big data and in the number of simultaneous users on the Internet places particular pressure on the need to carry out computing tasks “in parallel,” or simultaneously. In comparison, max-min fairness is the most popular and widely used policy in many existing, Massive data processing for effective trustworthiness modeling, ]. Distributed program 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. F.

A HDFS cluster consists of a name node that manages the file system metadata and data nodes that store the actual data [172]. Parallel computing Partial-order semantics are often referred to as true-concurrency semantics, because they are well suited to express concurrency of actions. Readers with a strong systems background can skip this chapter, but it is important for application developers to read it. It merges together these values to form a smaller set of values. Parallel computing and distributed computing are two types of computation. E. All of these 2 types It is a non-interleaving, partial-order process algebra that includes the classes of causal state operators and cause-addition operators. The Petri-net formalism is a well-known theory for describing and analyzing concurrent systems. Process-algebraic theories have in common that processes are represented by terms constructed from action constants and operators such as choice (alternative composition), sequential composition, and parallel composition (merge operator, interleaving operator). F. None of these,  17: Distributed program in a distributed computer running a is known as, A. C.Implementation A. The semantics of such a theory is a non-interleaving semantics or a non-interleaving process algebra. Similar to other distributed and parallel systems, Yahoo! 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. Cloud 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. The framework of labeled transition systems is used to define both a total-order semantics and a step semantics for labeled P/T nets. E. All of these The achievement of this objective involves several factors such as understanding interconnection structures, technological factors, granularity, algorithms and policies of system. Regarding the parallel computing model and classification discussed in Section 5.1, MapReduce programs are automatically executed in a parallel cluster-based computing environment [167]. A set of axioms or equational laws specifies which processes must be considered equal. An interesting aspect of bisimilarity is that it can be turned into a semantic equivalence called step bisimilarity [49] that provides the basis for a partial-order view on the behavior of concurrent systems. The resulting formalism is a step towards a framework supporting the development of complex concurrent systems. Distributed Computingcan be defined as the use of a distributed system to solve a single large problem by breaking it down into several tasks where each task is computed in the individual computers of the distributed system. D. Both A and B Copyright © 2020 Elsevier B.V. or its licensors or contributors. D. Loosely coupled A better understanding of these concepts can be useful in the development of formalisms that are sufficiently powerful to support the development of large and complex systems. Although important improvements have been achieved in this field in the last 30 years, there are still many unresolved issues. 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. E. All of these Flexibility It is explained how modular P/T nets in combination with the algebraic framework of Section 6 can be used to develop a compositional formalism for modeling and analyzing concurrent systems. Dan C. Marinescu, in Cloud Computing (Second Edition), 2018. C. 3 types A typical characteristic of a total-order semantics is that concurrency of actions is equivalent to non-determinism: A process that performs two actions in parallel is equivalent to a process that chooses non-deterministically between the two possible total orderings of the two actions. Starting in the mid-1980s, two technology advancements made distributed systems feasible. As a result, the cluster size is more than 2 PB of data in Hadoop and it loads more than 10 TB of data every day. C.
