    • Introduction to Grid Computing (I)End of 1998 the concept of "Grid computing" was introduced in the monograph "TheGrid: Blueprint for a New Computing Infrastructure" by I. Foster and C. Kesselman. 30 September 2012 Grid Computing Frameworks 4
    • Introduction to Grid Computing (II) ➔ The notion of grid computing: ➔ The term grid is chosen as an analogy to a power grid ! ➔ Grid computing is a special type of parallel computing ➔ How it differs from supercomputing? ➔ Few essential concepts related to grid computing: ➔ Utility computing ➔ Volunteer computing ➔ CPU scavenging ➔ Loosely coupled system ➔ Virtual supercomputers30 September 2012 Grid Computing Frameworks 5
    • Introduction to Grid Computing (III) ➔ grids typically share at least some of the following characteristics: ➔ They are numerous. ➔ They are owned and managed by different, potentially mutually-distrustful organizations and individuals. ➔ They are potentially faulty. ➔ They have different security requirements and policies. ➔ They are heterogeneous, e.g., they have different CPU architectures, run different operating systems, and have different amounts of memory and disk. ➔ They are connected by heterogeneous, multi-level networks. ➔ They have different resource management policies. ➔ They are likely to be geographically-separated (on a campus, in an enterprise, on a continent).30 September 2012 Grid Computing Frameworks 6

    • Grid Construction (IV)30 September 2012 Grid Computing Frameworks 12
    • Grid Frameworks (I) ➔ A software framework (or middleware) ➔ contains executables or tools ➔ provides inversion of control ➔ has a default behavior ➔ extensibility ➔ non-modifiable framework code30 September 2012 Grid Computing Frameworks 13
    • Grid Frameworks (II) ● Grid framework (or middleware), is a software stack that facilitates ● writing grid applications ● and manages the underlying grid infrastructure ➔ Grid frameworks can be categorized by the grid layers. ➔ Core middleware and toolkit: ➔ Globus, Gridbus (Alchemi, GridSim), UNICORE, Legion, GridGain, gLite ➔ User-level middleware and toolkit: ➔ SAGA, MetaMPI, Cactus, GrADS, Gridport, WebFlow, XtremeWeb30 September 2012 Grid Computing Frameworks 14
    • Globus Toolkit (I) ➔ Open source software toolkit for developing Grid applications ➔ The de facto standard for open source grid computing infrastructure ➔ Supported by industry leaders such as IBM, Intel, HP with others (The Globus Consortium) ➔ R&D project conducted by the “Globus Alliance” ➔ Work on the toolkit first began in 1996. Historically, the Globus Toolkit was used widely by three groups of people ➔ Grid builders ➔ Application developers ➔ Application framework developers30 September 2012 Grid Computing Frameworks 15
    • Globus Toolkit (II) ➔ Provides three main groups of services accessible through a security layer : 1. Resource Management 2. Data Management 3. Information Services30 September 2012 Grid Computing Frameworks 16
    • Globus Toolkit (III)Impact: Globus Toolkit have enabled many exciting new scientific and businessgrids. (Source: http://www.globus.org/alliance/impact/)30 September 2012 Grid Computing Frameworks 17
    • Gridbus Toolkit (I) ➔ Originated from Gridbus (GRIDcomputing andBUSiness) project. ➔ Toolkit for Service Oriented Grid and Utility Computing ➔ Supports development of grid infrastructure for eScience and eBusiness applications. ➔ Uses economic models (supply and demand) for efficient management of shared resources. ➔ Promotes commoditization of grid services at various levels: ➔ Raw resources level ➔ Application level ➔ Aggregated service level30 September 2012 Grid Computing Frameworks 18

    • Gridbus Toolkit (III)Impact: Gridbus Toolkit have enabled several exciting scientific and business grids.(Source: http://www.cloudbus.org/applications.html)● High Energy Physics and Grid Networks (BelleDataGrid): Melbourne School of Physics● NeuroGrid: Brain Activity Analysis on the Grid : Osaka University, Japan● KidneyGrid - Distributed Kidney Models Integration: Melbourne Medical School● Austronomy: Australian Virtual Observatory 30 September 2012 Grid Computing Frameworks 20
    • UNICORE (I) ➔ UNICORE (Uniform Interface to Computing Resources) ➔ is a ready-to-run Grid system including client and server software ➔ is part of the European Middleware Initiative. ➔ Project was initially funded by the Federal Ministry of Education and Research (BMBF) ➔ UNICORE was started before "Grid computing" ➔ developed by several European partners under the leadership of Jülich Supercomputing Centre. ➔ platform-independent, based on open standards and technologies such as Web Services ➔ mostly written in Java and is available as open source under BSD license and available at SourceForge. Current version is UNICORE 630 September 2012 Grid Computing Frameworks 21
    • UNICORE (II) ➔ The architecture of UNICORE 6 is three-layered in ➔ client layer, ➔ service layer ➔ and system layer UNICORE 6 Architecture30 September 2012 Grid Computing Frameworks 22
    • UNICORE (III)Impact: UNICORE6 has been the middleware of choice in numerous grids in EU.(Source: http://www.unicore.eu/community/projects/) 30 September 2012 Grid Computing Frameworks 23
    • Legion (I) ➔ Legion is an object-based metasystem developed at the University of Virginia. ➔ The software developed under the Legion project has been commercialized by a spin-off company called Avaki Corporation ➔ The Legion system uses an object-oriented approach. In the Legion system the following apply ➔ Everything is an object. ➔ Classes manage their instances ➔ Users can define their own classes ➔ The Legion interfaces are described in an Interface Definition Language (IDL).30 September 2012 Grid Computing Frameworks 24
    • Legion (II) ➔ Legion core objects support the basic services needed by the metasystem. ➔ Legion objects are independent, active, and capable of communicating with each other via unordered non-blocking calls. ➔ Some core objects in Legion are: ➔ Host objects: represent processors in Legion. ➔ Vault objects: represent persistent storage. ➔ Context objects: Context objects map context names to Legion object IDs ➔ Binding agents: A binding agent maps object IDs to physical addresses ➔ Implementation object: hides the storage details of object implementations ➔ Class object : is used to define and manage its corresponding Legion object. Class objects are given system-level responsibility.30 September 2012 Grid Computing Frameworks 25
