ORNL Chooses Moab on Cray XT3 Cluster, #10 Fastest in World

Cluster Resources, Inc.^TM announced earlier this month that Oak Ridge National Laboratory (ORNL) employed Moab Cluster Suite^® to manage its Cray XT3 Jaguar cluster, number ten in the Top500.org list, providing greater control and functionality.

ORNL's computing resources are among the fastest in the world. In order to provide optimal efficiency in utilization and more fine-tuned control, ORNL turned to Cluster Resources’ Moab technologies for a solution to manage job scheduling for their 5,294 node cluster.

“ORNL owns some of the most powerful hardware money can buy,” said David Jackson, CTO of Cluster Resources, Inc. “Adding Moab on top of their hardware empowers ORNL with one of the most powerful management tools available. We are pleased with how well Moab has worked on top of the Cray XT3 cluster to give administrators fine-tuned control. ORNL appears also to be pleased as they are now running Moab on their leadership-class computers.”

ORNL also uses Moab on “Phoenix”, a 1024 multi-streaming vector processor Cray X1E system, and “Ram”, a large SGI Altix system.

TORQUE* 2.1.0 AVAILABLE FOR DOWNLOAD

After more than five months of active development, TORQUE 2.1.0 is ready for immediate download. David Jackson, Chief Technology Officer at Cluster Resources, Inc., made the announcement earlier this month.

“There have already been over 6,000 downloads of the early releases of TORQUE 2.1.0 from leading sites representing commercial, government, and academic organizations and their feedback has been actively incorporated,” Jackson said. “The new release of TORQUE is more stable, more secure, more scalable, and more user friendly with improvements in virtually every aspect of operation.”

Details concerning updates and changes in the new version can be viewed at http://clusterresources.com/torquechangelog, and the new version can be downloaded at http://clusterresources.com/downloads/torque/.

“Many thanks go out to the dedicated contributors to the TORQUE project,” Jackson said. “It has become immensely successful, with over 10,000 downloads per month and use throughout all aspects of HPC. Please continue to let us know how we can make it even better!”

Cluster Resources, Inc. Announces Support and Maintenance Services for Gold Accounting and Allocation Manager

Cluster Resources, Inc. recently added Gold Accounting and Allocation Manager to its open source library. With the addition of Gold, Cluster Resources now maintains and supports three open source tools including TORQUE Resource Manager and Maui Cluster Scheduler^TM. In addition, two of Cluster Resources' commercial suites, Moab Cluster Suite^® and Moab Grid Suite^®, are both compatible with Gold.

Cluster Resources has hired the original developer of Gold, Scott Jackson, to assist with ongoing Gold enhancements and support.

“Gold represents a significant step in furthering the manageability and usability of supercomputers and computational grids.” said Jackson, Director of Software Engineering. “I created Gold to scale to clusters with tens of thousands of nodes and to manage the usage of hundreds of projects and users, while at the same time being reliable, secure and easy to use.”

Gold is an accounting system that tracks resource usage on high performance computers. Similar to a bank, accounts are established to pre-allocate available resources to specific users and projects within specified time frames to prevent overuse.

To find out more about Gold Accounting and Allocation Manager, visit www.clusterresources.com/gold. Gold is freely available to download from Cluster Resources' Web site, and users are welcome to subscribe to Gold's mailing list. To inquire about support for Gold, please either email Cluster Resources at info@clusterresources.com or call +1 (801) 873-3400.

DID YOU KNOW: Object Triggers

Moab can launch events or triggers based on certain events. For example, an administrator may want to send an email to the owner of a particular reservation when system usage drops below a specific threshold, or a user may want to launch an evaluation script five minutes before his job is scheduled for completion. Triggers can be associated with jobs, nodes, reservations or the core scheduler and enable actions to be taken when the specified event, offset and threshold criteria are satisfied.

There are three ways to create triggers. A trigger can be associated with a standing reservation, node or the scheduler by using the TRIGGER parameter with SRCFG, SCHEDCFG, or NODECFG. You can also add a trigger to an already existing reservation, node, job or the scheduler itself by using the mschedctl command. Or, to add a trigger to an administrative reservation, use the mrsvctl command.

For full instructions on how and when to use triggers, please visit www.clusterresources.com/triggers.
