Message Passing is a popular mechanism used to enable inter-process communication in parallel and distributed computing. Many complex scientific and engineering applications that are executed on clusters have been developed based on this communication model. Due to the huge amount of computing power being wasted in desktops, there is an increasing interest in using these computers to execute complex applications. However, most of the current middleware systems are aimed at executing only embarrassingly parallel applications, i.e. with no inter-process communication. Moreover, most existing middleware systems are based on Linux. Nevertheless, it is well-known that the desktop machines in the world are predominantly based on the Windows operating system. Hence, in this work we present the design implementation and evaluation performance of a Windows-based implementation of two message passing models, Message Passing Interface (MPI) and Bulk Synchronous Parallel (BSP), over the Alchemi grid computing framework. © 2006 ACM.

Journal of grid computing 2005年第3-4期3卷 171-200页

作者： Yu, Jia Buyya, Rajkumar Grid Computing and Distributed Systems (GRIDS) Laboratory Department of Computer Science and Software Engineering The University of Melbourne Melbourne Vic. Australia

With the advent of grid and application technologies, scientists and engineers are building more and more complex applications to manage and process large data sets, and execute scientific experiments on distributed resources. Such application scenarios require means for composing and executing complex workflows. Therefore, many efforts have been made towards the development of workflow management systems for grid computing. In this paper, we propose a taxonomy that characterizes and classifies various approaches for building and executing workflows on grids. We also survey several representative grid workflow systems developed by various projects world-wide to demonstrate the comprehensiveness of the taxonomy. The taxonomy not only highlights the design and engineering similarities and differences of state-of-the-art in grid workflow systems, but also identifies the areas that need further research. © Springer Science+Business Media, Inc. 2006.

Utility computing has been anticipated to be the next generation of computing usage. Users have the freedom to easily switch to any commercial computing service to complete jobs whenever the need arises and simply pay only on usage, without any investment costs. A commercial computing service however has certain objectives or goals that it aims to achieve. In this paper, we identify three essential objectives for a commercial computing service: (i) meet SLA, (ii) maintain reliability, and (iii) earn profit. This leads to the problem of whether a resource management policy implemented in the commercial computing service is able to meet the required objectives or not. So, we also develop two evaluation methods that are simple and intuitive: (i) separate and (ii) integrated risk analysis to analyze the effectiveness of resource management policies in achieving the required objectives. Evaluation results based on five policies successfully demonstrate the applicability of separate and integrated risk analysis to assess policies in terms of the required objectives. © 2007 IEEE.

The advent of service-oriented grid computing has resulted in the need for grid resources such as clusters to enforce user-specific service needs and expectations. Service Level Agreements (SLAs) define conditions which a cluster needs to fulfill for various jobs. An example of SLA requirement is the deadline by which a job has to be completed. In addition, these clusters implement job admission control so that overall service performance does not deteriorate due to accepting exceeding amount of jobs. However, their effectiveness is highly dependent on accurate runtime estimates of jobs. This paper thus examines the adverse impact of inaccurate runtime estimates for deadline constrained job admission control in clusters using the Earliest Deadline First (EDF) strategy and a deadline-based proportional processor share strategy called Libra. Simulation results show that an enhancement called LibraRisk can manage the risk of inaccurate runtime estimates better than EDF and Libra by considering the risk of deadline delay. © 2006 IEEE.

In this work, we present two perspectives of grid computing by using two different grid middleware as examples: an Enterprise grid using Xgrid and a Global grid with gridbus. We also present the integration of Enterprise and Global grids by proposing the integration of gridbus Broker with diverse enterprise grid middleware including Xgrid, PBS, Condor and SGE. The sample performance results demonstrate the usefulness of this integration effort. © Springer-Verlag Berlin Heidelberg 2005.

Efficient scheduling is a key concern for the effectual execution of performance driven grid applications, such as workflows. Many list heuristics have been developed for scheduling workflows in centralized grid environment. However, in this paper, we present a distributed list heuristic for decentralized scheduling of workflow applications in global grids. The simulation results show that the proposed scheduling approach is scalable with respect to increased workload on the system. © 2009 IEEE.

Dependable workflow scheduling in global grids

In this paper, a reputation-based grid workflow scheduling algorithm is proposed to counter the effect of inherent unreliability and temporal characteristics of computing resources in large scale, decentralized grid overlays. The proposed approach builds upon structured peer-to-peer indexing and overlay networking techniques to create a scalable wide-area networking of grid sites for supporting dependable scheduling of applications. The scheduling algorithm considers reliability of a grid resource as a statistical property, which is globally computed in the decentralized grid overlay based on dynamic feedbacks or reputation scores assigned by individual service consumers (grid Resource Brokers). The proposed algorithm can dynamically adapt to changing resource conditions and offer significant performance gains as compared to traditional approaches in the event of unsuccessful job execution or resource failure. We evaluate and demonstrate the feasibility of our approach through an extensive trace driven simulation. The results show that our scheduling technique can reduce the makespan up to 50% and successfully isolate the failure-prone resources from the system. © 2009 IEEE.

International Conference on Advanced computing and Communications (ADCOM)

作者： Rajkumar Buyya Grid Computing and Distributed Systems (GRIDS) Laboratory University of Melbourne Australia

grid computing, one of the latest buzzwords in the ICT industry, is emerging as a new paradigm for Internet-based parallel and distributing computing. Despite a number of advances in grid computing, resource management and application scheduling in such environments continues to be a challenging and complex undertaking. This is due to geographic distribution of grid resources owned by different organizations with different usage policies, cost models and varying load and availability patterns with time. This tutorial introduces fundamental principles of grid computing and computational economy and discusses how they impact on emerging computational and data grid technologies. It identifies resource management challenges and introduces new challenges and requirements introduced by the grid economy on grid service providers (GSPs) and grid service consumers. The tutorial presents a service-oriented grid architecture inspired by computational economies and demonstrates how it can be realized by leveraging the existing grid technologies and building new economic-oriented capabilities and components. We present solutions to these challenges based on our experience in designing and developing market-oriented gridbus technologies such as grid Market Directory, grid Bank, grid Service Broker, Workflow Engine, and SLA-based enterprise grid Resource Allocation system. Case studies on the use of gridbus middleware in the creation of various e-science and e-business applications and their deployment on national/international utility-oriented grids along with its impact on emerging cloud computing paradigm will also be highlighted.

Peer-to-Peer (P2P) computing is said to be the next wave of computing after client-server and web-based computing. It provides an opportunity to harness a lot of idle peer-resources such as desktop computers across the Internet, for solving large-scale computing applications. Each peer is autonomous and it needs incentive for sustained contribution of its resources to P2P applications. In addition, a flexible and efficient job scheduling is needed to harvest the idle computing power as cheaply and economically as possible. This paper introduces an economic based job scheduler for mapping jobs to resources in P2P computing environment. The scheduler has been implemented with the Compute Power Market (CPM) system developed using Sun JXTA P2P technology. Our scheduler can be configured depending on users’ quality of service requirements such as the deadline and budget constraints. Our scheduler follows a hierarchy scheme. The design allows multiple consumers and multiple providers to schedule and run jobs. To allow wider support for a wide variety of applications, the system is designed to allow easy ‘plug in’ of user applications. © Springer-Verlag Berlin Heidelberg 2004.
