IBM RELEASES GRID TOOLBOX
What is IBM Grid Toolbox?
The IBM Grid Toolbox is a set of installable packages that includes the
Globus Toolkit 2.2 with additional documentation and custom installation
scripts written for IBM eServer hardware running AIX and Linux. IBM
LoadLeveler (AIX 5.1) enablement as an alternative job manager is
provided.
The IBM Grid Toolbox is an integrated set of tools and software that
facilitate the creation of grids and applications that can exploit the
advanced capabilities of the grid using a combination of this toolbox and
other technologies.
The IBM Grid Toolbox can be used in the following ways:
- To allow a site that wants to participate in a computational grid to
contribute resources to a grid's pool of resources
- To provide access to other grid resources without contributing any of a
site's own resources, that is, assuming that the appropriate access policies
have been negotiated with the owners of the other resources
- To provide other services, such as single sign-on authentication, without
needing to contribute computational resources.
How does it work?
The components of the IBM Grid Toolbox can be used either independently or
together to develop useful grid applications and programming tools.
The IBM Grid Toolbox components are as follows:
Globus Resource Allocation Manager (GRAM):
- The GRAM provides resource allocation and process creation, monitoring,
and management services.
- GRAM implementations map requests expressed in a Resource Specification
Language (RSL) into commands to local schedulers and computers.
- Access to GRAM is available through the gatekeeper, the access-regulation
tool.
Grid Security Infrastructure (GSI):
- The GSI provides a single sign-on authentication service, with
support for local control over access rights and mapping from global to local
user identities.
- GSI may be used independently and, in fact, has been integrated into
numerous programs that are independent of the rest of the Grid
Toolbox.
Monitoring and Discovery Service (MDS):
- The MDS is an integrated information service distributed across Grid
Toolbox-enabled resources that provides information about the state of the
grid infrastructure.
- The service is based on the Lightweight Directory Access Protocol
(LDAP).
Global Access to Secondary Storage (GASS):
- The GASS service implements a variety of automatic and programmer-managed
data movement and data access strategies, enabling programs running at remote
locations to read and write local data.
Globus Replica Catalog:
- The replica catalog provides mappings between logical names for files or
file collections and one or more copies of the objects on physical storage
systems.
Grid Toolbox I/O:
- Grid Toolbox I/O provides an interface to TCP, UDP, and file I/O. It
supports both synchronous and asynchronous interfaces, multithreading, and
integrated GSI security.
Simple CA:
- The Simple CA provides a personal certificate authority (CA) for testing
and developing grids and grid applications.
