Glossary

Component	Description	More Info
Cluster	A collection of machines, called hosts, on which Grid Engine system functions occur.	See CONFIGURING CLUSTERS.
Master Host	The master host is central component of OGE. The master host runs the master daemon and usually also runs the scheduler. The master host requires no further configuration other than that performed by the installation procedure. By default, the master host is also an administration host and a submit host.	For information about how to initially set up the master host, see Oracle Grid Engine Installation and Upgrade Guide to install the master host. For information about how to configure dynamic changes to the master host, see Oracle Grid Engine Administration Guide for configuring hosts.
Master Daemon	The master daemon does the following: Accepts incoming jobs from users. Maintains tables about hosts, queues, jobs, system load, and user permissions. Performs scheduling functions and requests actions from execution daemons on the appropriate execution hosts. Decides which jobs are dispatched to which queues and how to reorder and reprioritize jobs to maintain share, priority, or deadline	See Oracle Grid Engine Administration Guide for configuring hosts.
Execution Host	Systems that have permission to run Grid Engine system jobs. These systems host queue instances, and run the execution daemon. Execution hosts are systems that have permission to execute jobs. Therefore, queue instances are attached to the execution hosts.	An execution host is initially set up by the installation procedure, as described in Oracle Grid Engine Installation and Upgrade Guide to install execution hosts. For installation planning guidance, see Oracle Grid Engine Installation and Upgrade Guide for host system requirements. See Oracle Grid Engine Administration Guide for more information on managing your cluster.
Execution Daemon	The execution daemon receives jobs from the master daemon and executes them locally on its host. An execution daemon is responsible for the queue instances on its host and for the running of jobs in these queue instances. Periodically, the execution daemon forwards information such as job status or load on its host to the master daemon.	See Oracle Grid Engine Administration Guide for configuring hosts.
Scheduler	The scheduler is responsible for prioritizing pending jobs and deciding which jobs to schedule to which resources.	For more information on the scheduler, see Oracle Grid Engine Administration Guide for managing the scheduler.
Administration Host	Administration hosts are hosts that have permission to carry out any kind of administrative activity for the Grid Engine system.	See Oracle Grid Engine Administration Guide for configuring hosts.
Submit Host	Submit hosts enable users to submit and control batch jobs only. In particular, a user who is logged in to a submit host can submit jobs with the `qsub` command, can monitor the job status with the `qstat` command, and can use the Grid Engine system OSF/1 Motif graphical user interface QMON, which is described in QMON, the Grid Engine System's Graphical User Interface.	See Oracle Grid Engine Administration Guide for configuring hosts.
Shadow Master Host	Shadow master hosts reduce unplanned cluster downtown. One or more shadow master hosts may be running on additional nodes in a cluster. In the case that the master daemon or the host on which it is running fails, one of the shadow masters will promote the host on which it is running to the new master daemon system by locally starting a new master daemon.	See Oracle Grid Engine Installation and Upgrade Guide for information about how to install the shadow master host.
DRMAA	The optional Distributed Resource Management Application API (DRMAA) automates Grid Engine functions by writing scripts that run Grid Engine commands and parse the results.	See Automating Grid Engine Functions Through DRMAA.
ARCo	The optional Accounting and Reporting Console (ARCo) enables you to gather live reporting data from the Grid Engine system and to store the data for historical analysis in the reporting database, which is a standard SQL database.	For more information, see Using the Accounting and Reporting Console.
SDM	The optional Service Domain Manager (SDM) module distributes resources between different services according to configurable Service Level Agreements (SLAs). The SLAs are based on Service Level Objectives (SLOs). SDM functionality enables you to manage resources for all kind of scalable services.
