Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee GRID (GRID). The pres

19、ent document is related to document 102-828 (GCM Interoperability Application Description). Introduction The purpose of the present document is to offer a standard, uniform way of describing grid resources, so as to make these resources available to grid-based applications. When building a grid, one

20、 is confronted to several problems, among which: choosing a grid framework, as many are available. when running a grid-enabled application, one must rewrite configuration directives when switching to a different grid framework. a grid can be built on widely different hardware infrastructures, from a

21、n heterogenous set of desktop machines to a dedicated cluster, or even any combination of those. grid infrastructures can also be very dynamic, it should be easy to add or remove machines, and such changes should be transparent to users. To simplify this, the GCM Interoperability Deployment standard

22、 offers a uniform way to describe grid resources, how they are connected to one another, how they can be activated, and how they can be accessed. A grid infrastructure is modelized with several entities: Host, Bridge, and Group (see definitions clause). By combining these entities, one can describe

23、the physical infrastructure of the grid, i.e. how the machines it includes are configured and networked together. The GCM has been first defined in the NoE CoreGRID (42 institutions). A reference Open Source implementation has been tested in the 4 previous GRID Plugtests organized from 2004 to 2007

24、by ETSI, and will also be part of the forthcoming 5thone in 2008. The GridCOMP EU project (FP6, started June 2006 to November 2008) is working to further assess and experiment with the specification. ETSI ETSI TS 102 827 V1.1.1 (2008-08) 7 1 Scope The present document describes an XML schema for des

25、cribing resources to be used in distributed and parallel infrastructures like enterprise and scientific grids and job schedulers. The standard will help enterprises and laboratories to manage large-scale computer and telecom infrastructures with the necessary virtualization. Its primary audience are

26、 grid system administrators who will need to write deployment descriptors for their grid. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

37、s and definitions apply: bridge: GCM Deployment concept that represents a machine through which multiple machines are accessed NOTE: A typical example is a cluster frontend (see frontend). certificate: electronic document which incorporates a digital signature to bind together a public key with an i

38、dentity - information such as the name of a person or an organization, their address, and so forth certificate authority: entity which issues digital certificates for use by other parties cluster: set of loosely-coupled machines working together so that they are seen as a single computer ETSI ETSI T

39、S 102 827 V1.1.1 (2008-08) 9 Core (CPU Core): processing unit within a processor chip, effectively seen as a CPU from the Operating System NOTE: For instance, a dual-core CPU will be seen as two CPUs by the OS. deployment descriptor: XML file following the schema specified in the present document, w

40、hich describes what grid resources are to be deployed and how frontend: in a physical network, a single machine acting as a gateway for a set of machines NOTE: This is often the case for machine clusters, where individual machines are not accessible directly. Grid Component Model (GCM): component ar

41、chitecture and framework for the portability, and reusability of Grid applications, the integration with SOA infrastructures, and providing interoperability of GRID systems group: GCM Deployment concept that represents a set of machines (i.e. hosts, see definition) and the grid protocol through whic

42、h they can be accessed NOTE: These machines may all be sharing the same configuration (OS type, installation path of executable etc.), but it may also only have the same grid protocol while having very different configurations. A group is generally used to represent a cluster. host: GCM Deployment c

43、oncept which represents a single physical machine on a network NOTE: A GCM Deployment model can be seen as a tree, and hosts are the leaves. Host Capacity (HC): number of programs or VM per Host NOTE: An indicator of the number of programs to be executed in parallel on a host. infrastructure: organi

44、zed set of processing resources which form a grid job scheduler: program which purpose is to manage a queue of program execution requests (jobs) in order to run them in turn, or at a specified time node: GCM Deployment concept that represents a location to execute a computation NOTE: At execution, a

45、 node is a place where a program or an activity can be executed. This can be a single physical machine (a host), or, in the case of a multi-processor / multi-core machine, a single processor or a single core within a machine. resource: processing unit which is a building part of the grid NOTE: A res

46、ource can either be a host (a single physical machine), a bridge (a frontend machine providing access to several others), or a group (a set of identical machines).

However, these indicators are by no means absolute. They can be tuned to take into account the specifications of the platform
