Local Resource Managers LRM
From BeSTGRID
Contents |
[edit] Introduction
The term Local Resource Manager (LRM), serves as a placeholder name for a number of technologies that all manage, within an institition-local context as opposed to managing interactions initiated externally, computational resources.
The equivalent term for those technologies that manage externally initiated interactions is Gateway.
The various technologies that can be described as LRMs perform a common enough set of management operations that allow those who deploy and adminster them, to talk in generic terms about those operations. The use of the term Local Resource Manager performs a similar function for the software packages themselves.
The management operations of an LRM, within a computational grid context, will usually include, but need not exclusively be limited to, the scheduling of computational tasks across the computational resources.
[edit] BeSTGRID's LRM technologies
The various presentations of overviews of technologies deployed within BeSTGRID
suggest that the following LRMs are currently in widespread use:
[edit] Condor
[edit] Project Homepage
http://www.cs.wisc.edu/condor/
states that:
The goal of the Condor® Project is to develop, implement, deploy, and evaluate mechanisms and policies that support High Throughput Computing (HTC) on large collections of distributively owned computing resources.
It is developed by the Condor Team at the University of Wisconsin Madison
[edit] BeSTGRID's Precis
Condor is often used to build cycle scavenging grids, these grids typically make use of lab or staff machines when the main user isn't actively using them. This allows a large pool of potentially underutilised resources to be harnessed and able to do useful computations.

[edit] PBS/Torque
[edit] Project Homepage
http://www.clusterresources.com/pages/products/torque-resource-manager.php
states that:
TORQUE is an open source resource manager providing control over batch jobs and distributed compute nodes.
TORQUE is based on an original product called Portable Batch System (PBS) and whilst the two names are still in use and seemingly interchangeable, PBS is more likely to refer to a now commericially maintained version, although the company which currently distributes PBS Professional, also have OpenPBS which they don't mantain.
[edit] BeSTGRID's Precis
Torque is the LRM of choice for the two main providers of computational grid resources within BeSTGRID, the Universities of Auckland and Canterbury.

[edit] Sun Grid Engine
[edit] Project Homepage
http://gridengine.sunsource.net
states that:
The Grid Engine project is an open source community effort to facilitate the adoption of distributed computing solutions. ... the Grid Engine project provides enabling distributed resource management software for wide ranging requirements from compute farms to grid computing.
References to Sun Grid Engine as simply Grid Engine may increase, following Oracle's takeover of Sun Microsystems, who initially open-sourced their Codine product as SGE. The SGE acronym seems likely to live on for a while, not least because of the visibility of the term within its operating environment.
[edit] BeSTGRID's Precis
SGE is the default LRM for Rocks clusters, Rocks itself being a popular, packaged, operating system distribution aimed at simplifying the administration of clusters.
