[edit] Standards implementation
The Globus Toolkit is an implementation of the following standards:
- Open Grid Services Architecture (OGSA)
- Open Grid Services Infrastructure (OGSI) -- originally intended to form the basic “plumbing” layer for OGSA, but has been superseded by WSRF and WS-Management.
- Web Services Resource Framework (WSRF)
- Job Submission Description Language (JSDL)
- Distributed Resource Management Application API (DRMAA)
- WS-Management
- WS-BaseNotification
- SOAP
- WSDL
- Grid Security Infrastructure (GSI)
The Globus Toolkit has implementations of the OGF-defined protocols to provide:
- Resource management: Grid Resource Allocation & Management Protocol (GRAM)
- Information Services: Monitoring and Discovery Service (MDS)
- Security Services: Grid Security Infrastructure (GSI)
- Data Movement and Management: Global Access to Secondary Storage (GASS) and GridFTP
[edit] Compatible third-party software
A number of tools can function with Globus Toolkit, including:
- WebCom and WebCom-G [2]
- Nimrod tools for meta-scheduling and parametric computing
- Gridbus Grid Service Broker
- Grid Portal Software such as GridPort, OGCE and GridSphere
- Grid Packaging Toolkit (GPT)
- MPICH-G2 (Grid Enabled MPI)
- Network Weather Service (NWS) (Quality-of-Service monitoring and statistics)
- Condor (CPU Cycle Scavenging) and Condor-G (Job Submission)
- HPC4U Middleware (Fault Tolerant and SLA aware Grid Middleware)
- GridWay metascheduler
XML-based web services offer a way to access the diverse services and applications in a distributed environment.
[edit] Globus distributions
In 2004 Univa Corporation began providing commercial support for the Globus Toolkit using a business model similar to that of Red Hat.
[edit] Job schedulers
GRAM (Grid Resource Allocation Manager), a component of the Globus Toolkit, officially supports the following job schedulers or batch-queuing systems:
- Portable Batch System, a computer software job scheduler that allocates network resources to batch jobs.
- Condor High-Throughput Computing System, a software framework for coarse-grained distributed parallelization of computationally intensive tasks.
- Load Sharing Facility, a commercial computer software job scheduler.
Unofficial job schedulers that can be used with the Globus Toolkit:
- Sun Grid Engine, an open source batch-queuing system, supported by Sun Microsystems. Globus does not officially support SGE, but third parties offer methods to integrate it:
- The London e-Science Center has created a "Transfer-queue over Globus (TOG)" package and provides instructions on how to configure a Globus Toolkit 2 or 3 or a Globus Toolkit 4 server so that it can submit jobs for execution on a local Sun Grid Engine installation.
- Other commercial solutions are available for integrating SGE into Globus Toolkit also.
