Projects like SETI@home have demonstrated the tremendous capabilities of Internet-connected commodity resources. The rapid improvement of commodity components makes the global computing platform increasingly viable for other large-scale data and compute-intensive applications. In this paper, we study how global computing can accommodate new types of applications. We describe a global computing model that captures resource characteristics and instantiate this model with data from several surveys and studies. We propose performance metrics for global computing applications and evaluate two scheduling mechanisms in simulation. We then draw conclusions concerning the development and enhancement of global computing systems. © 2002 IEEE.

We develop a novel framework for supporting e-science applications that require streaming of information between sites. Using a Synchronous Dataflow (SDF) model, our framework incorporates the communication times inherent in large scale distributed applications, and can be used to formulate the bandwidth allocation problem with throughput constraints as a multi-commodity linear programming problem. Our algorithms determine how much bandwidth is allocated to each edge while satisfying temporal constraints on collaborative tasks. Simulation results show that the bandwidth allocation by the formulated linear programming outperforms the bandwidth allocation by simple heuristics. © 2010 IEEE.

In distributed and high performance applications it it is necessary to discover the aggregate resource capabilities of the collaborating peers. Another requirement of these applications is to locate the resources meeting the given aggregate search criteria. In this paper we present an unstructured peer-to-peer approach to aggregate node selection for resource management. Our objective is to efficiently calculate the aggregate value and search the aggregate node whose attribute matches or falls in the proximity of this value. Our contribution also includes the inclusion of an explicit network for aggregate query routing. We evaluated our protocol for accuracy, efficiency and communication cost through detailed simulations. Copyright 2008 ACM.

This research discusses the performance evaluation of distributed database systems in a cloud computing environment Cloud computing environments allow data and applications to be stored and deployed on infrastructure located in different parts of the world. However, the use of distributed database systems in cloud computing environments can cause performance issues, such as complex data access and factors such as network latency, security, and scalability that affect system performance. Therefore, performance evaluation of distributed database systems is necessary to ensure effective data management across the infrastructure. The purpose of this research is to measure and understand the performance of distributed database systems in a cloud computing environment. This is important because proper performance evaluation is needed to ensure distributed database systems can operate effectively and efficiently in such environments. This research will analyze the features of distributed database systems, factors that affect performance, how to measure and compare system performance, and how to improve system performance. Analyzing the performance of distributed database systems in a cloud computing environment can help users choose the most appropriate and efficient cloud computing platform for their business needs and improve operational efficiency. © 2023 IEEE.

Dynamic loop scheduling (DLS) algorithms provide application-level load balancing of loop iterates, with the goal of maximizing application performance on the underlying system. These methods use run-time information regarding the performance of the application's execution (for which irregularities change over time). Many DLS methods are based on probabilistic analyses, and therefore account for unpredictable variations of application and system related parameters. Scheduling scientific and engineering applications in large-scale distributed systems (possibly shared with other users) makes the problem of DLS even more challenging. Moreover, the chances of failure, such as processor or link failure, are high in such large-scale systems. In this paper, we employ the hierarchical approach for three DLS methods, and propose metrics for quantifying their robustness with respect to variations of two parameters (load and processor failures), for scheduling irregular applications in large-scale heterogeneous distributed systems.

Using an interactive software environment for the parallelization of real-world scientific applications

international JOURNAL OF COMPUTER MATHEMATICS 2007年第2期84卷 167-175页

The parallelization of real-world compute intensive Fortran application codes is generally not a trivial task. If the time to complete the parallelization is to be significantly reduced then an environment is needed that will assist the programmer in the various tasks of code parallelization. In this paper the authors present a code parallelization environment where a number of tools that address the main tasks such as code parallelization, debugging and optimization are available. The ParaWise and CAPO parallelization tools are discussed which enable the near automatic parallelization of real-world scientific application codes for shared and distributed memory-based parallel systems. As user involvement in the parallelization process can introduce errors, a relative debugging tool (P2d2) is also available and can be used to perform nearly automatic relative debugging of a program that has been parallelized using the tools. A high quality interprocedural dependence analysis as well as usertool interaction are also highlighted and are vital to the generation of efficient parallel code and in the optimization of the backtracking and speculation process used in relative debugging. Results of benchmark and real-world application codes parallelized are presented and show the benefits of using the environment.

26th IEEE international Parallel and distributed Processing symposium (IPDPS) / Workshop on High Performance Data Intensive computing

Heterogeneity in secondary characteristics of different HPC target platforms is the focus of this paper. Clusters, grids, and (IaaS) clouds may appear straightforward to configure to be interchangeable - but our experiences with mainstream parallel codes for CFD demonstrate that secondary attributes - support software, interconnect type, availability, access, and cost - expose heterogeneous aspects that impact overall effectiveness of application execution. The emergence of clouds as alternatives to grids and local resources for parallel HPC codes portends "computing as a utility" in science and engineering domains. Our experiences provide preliminary insights into characterizing these different types of platforms to which users typically have access - and show where the tradeoffs can be, in terms of deployment effort, actual and nominal costs, application performance, and availability (both in terms of resource size and time to gain access). For our test application, we report that each of the platforms to which we had access had its particular benefits and drawbacks in terms of the above attributes. More generally, our experiences may provide an example preview into what developers and users can expect when selecting a "utility provider" and specific instance thereof for a particular run of their application.

Utility computing was a vision stated more than 40 years ago. It refers to the idea that computing resources and services can be delivered, utilized, and paid for as utilities such as water or electricity. The recent emergence of cloud computing is making this vision realizable. Examples of efforts in this area include Infrastructure as a Service (IaaS) providers like Amazon EC2 and Software as a Service (SaaS) providers like Google AppEngine and Microsoft Azure. More recently, there is a growing interest in the use of cloud computing for scientific computing, as evidenced by a large-scale funded project like Magellan, and new workshops. Copyright 2010 ACM.

Resources allocation and scheduling has been recognised as an important topic for business process execution. However, despite the proven benefits of using Cloud to run business process, users lack guidance for choosing between multiple offering while taking into account several objectives which are often conflicting. Moreover, when running business processes it is difficult to automate all tasks. In this paper, we propose three complementary approaches for Cloud computing platform. On the other side, elastic computing, such as Amazon EC2, allows users to allocate and release compute resources (virtual machines) on-demand and pay only for what they use. Therefore, it is reasonable to assume that the number of virtual machine is infinite while the number of human resources is finite. This feature of Clouds has been called "illusion of infinite resources". In this paper, we design an allocation strategy for Cloud computing platform taking into account the above characteristics. More precisely, we propose three complementary hi-criterion approaches for scheduling business process on distributed Cloud resources.
