Management


Area Director: Andre Merzky

The Management Area covers the management of essential grid operating components, such as policies, processes, equipment, and data, for overall effectiveness of grid systems, storage, applications, and services.

Access to Remote Instrumentation in a distributed environment – Working Group (ARI-WG)
Group Information
Group Type: Working Group
 
Group Description
This working group is spawned by RISGE-RG and will focus its effort on providing a Shared Information Model (SIM) and defining concrete interfaces for accessing remote instruments. There is a need in the community for accessing remote instruments by using standard interfaces that are well defined and specified by standard approaches/procedures. The main purpose of this working group will be to standardize approaches in remote access interfaces to instruments through our SIM. Target devices are all kind of instruments including distributed sensor networks. As such, it concerns mostly the services for steering and monitoring instrument resources, granting security and authorization (policy), accessing combined or multiple devices, performing a calibration phase, and also services for acquiring data from instruments ,operating on files and streams.
 
Group Focus and Scope
The initial RISGE-RG collected a number of use cases which are published in the RISGE-RG Document “RISGE-RG Collection of Use Cases? (GFD-I.168). The effort of this working group will be focused initially on these use cases, also taking into account the standards and use cases in the field of sensors (OGC – SWE) and the CIMA interface and implementation. During its work, the group will consider the outcome of other groups such as SAGA, OGSA ByteIO, and GLUE.
One of the main objectives to be achieved is simplicity of the interfaces, which will create the standard SIM to assure reliable implementations.
The group will work on the recommendation document (Specification 1.0) for defining interfaces in the new SIM for accessing the remote instruments.
The WG will also continue to identify projects outside OGF with similar focus and goals and will seek their input in the development and implementation of the services.

Distributed Computing Infrastructure Federation Working Group (DCIFED-WG)
Group Information
Group Type: Working Group
Group Secretary(s): Andy Edmonds
 
Group Description
The purpose of this group is the development and spread-out of a practical set of protocols and formats to interface between different types of Distributed Computing Infrastructures in a secure, SLA-managed manner. We will focus on the federation of such DCIs for two usage scenarios: (1) delegation of workload from one domain into the other, covering job description, submission, and monitoring; and (2) leasing of resources, including resource definition, provisioning, and monitoring. The work of this group will base on existing protocols and standards in order to ensure fast delivery and highest possible synchronization with other groups.
 
Group Focus and Scope
Infrastructure federation is becoming an increasingly important issue for modern Distributed Computing Infrastructures (DCIs): Dynamic elasticity of quasi-static Grid environments, incorporation of special-purpose resources into commoditized Cloud infrastructures, cross-community collaboration for increasingly diverging areas of modern e-Science, and Cloud Bursting pose major challenges on the technical level for many resource and middleware providers. Especially with respect to increasing cost of operating data centers, the intelligent, yet automated and secure sharing of resources is a key factor for success.

The DCI Federation Working Group (DCIfed-WG) will, after initial research, deliver a specification for the automatically negotiated, SLA-secured, dynamically provisioned federation of resources and for Grid- and Cloud-type infrastructures. The scope of the specification will include (1) the delegation of workload from one domain into the other, covering job description,
submission, and monitoring; and (2) leasing of resources, including resource
definition, provisioning, and monitoring.

This group will focus on the creation of a specification for compute-centric federation. This is both necessary and sufficient to allow for interoperable implementations.

DCIfed aims to address the needs of different stakeholders:
* Providers to incorporate dynamic elasticity into their DCI based on current demand;
* Aggregators to provide a simplified view on infrastructure federations;
* Integrators to offer advanced management services beyond the boundaries of current infrastructure types;
* Vendors to use DCI-abstracted data centers in an application-driven, on-demand fashion;
* Users to benefit from otherwise separate infrastructures in a coherent, unified, and transparent way.

The scope will be limited to the high-level federation of DCIs with respect to delegation of workload and leasing of resources. This includes means for describing, negotiating, and agreeing upon the service provided and consumed by the federated systems; the description, submission, and monitoring of workload; the definition, provisioning, and monitoring of resources. Data management details beyond providing endpoints for transfer are excluded; the same holds for network management details beyond the absolute necessities for leasing a resource (i.e. providing a publicly accessible IP).

There are a number of existing standards within OGF which shall serve as basis for the full protocol, interface, and data representation documents for DCIfed:

* WS-Agreement
* JSDL
* GLUE
* OGSA-BES
* OCCI
* UR

GLUE Working Group (GLUE)
Group Information
Group Type: Working Group
 
Group Description
The GLUE Working Group will provide a recommendation for an abstract information model which is expressed via a schema independent of information system implementations. The schema will define the set of attributes and attribute semantics, the relationship between the attributes and the syntax for attribute values where applicable.
 
Group Focus and Scope
Focus

The main purpose of the schema is to facilitate interoperation between Grid infrastructures via enabling the development of interoperating Grid middleware components and as such the schema will be designed in response to existing use cases. The focus will be on use cases which span multiple Grid infrastructures that may rely on different middleware. The collected use cases will be published as a live document.As a starting point for the work, existing schemas such the Glue Schema 1.3 and Nordugrid Schema will be considered. The abstract schema definition will enable concrete schema to be rendered in various formats. These renderings will be the reference implementations for the available information services.

Scope

The schema will be based on the already existing Glue schema (version 1.3), which is already being used in many production Grids. The work will be a major revision of this schema and the result will become Glue version 2.0. This schema should consider the existing use cases of the Glue schema 1.3, NorduGrid schema, the CIM vendor extension from NAREGI and others. Additional use cases will be collected, evaluated and prioritized.

Goals

The goal of the GLUE-WG is to define a specification document defining the abstract schema GLUE 2.0 satisfying the collected use cases. Moreover, reference implementations for the main Grid Information Services should be provided.

Usage Record WG (UR-WG)
Group Information
Group Type: Working Group
 
Group Description
In order for resources to be shared, sites must be able to exchange basic accounting and usage data in a common format. This working group proposes to define a common usage record based on those in current practice.
