OPTIMIZING YOUR COMPUTE RESOURCES
NEWS / ANNOUNCEMENTS
Cluster Resources, Inc. is proud to celebrate the anniversaries of its two flagship products this year. 2006 marks the 10-year anniversary of the 1996 creation of Maui, as well as the five-year anniversary of Moab, created in 2001.
“The creation of Maui, and later Moab, has unleashed enormous potential for supercomputing,” said Dave Jackson, developer of both Maui and Moab. “Both products have been part of the tremendous evolution in the clustering scene over the years, and both have proven flexible enough to adapt to cluster changes, continually improving optimization.”
Moab expands upon the success of Maui's open source cluster scheduling capabilities by improving the cluster, grid, and utility management tools. Moab also provides organizations with a flexible architecture and intelligent scheduling to increase utilization of resources.
To learn more about what Cluster Resources is doing with Moab, Maui and other products, go here.
Cluster Resources has officially moved to its new headquarters located in Provo, Utah. More than double the size of its previous facilities, Cluster Resources' new location will aid the company's rapid growth in terms of employees, general infrastructure and testing facilities.
“Our new offices will provide greater convenience for our customers and partners,” said Amber Webb, Communications Manager at Cluster Resources. “The location, amenities and room for additional growth will aid in our endeavor to provide the best possible service.”
Cluster Resources, which experienced more than 100 percent growth in the past year, wishes to thank our customers and partners for their continued support as we have expanded our products and services. We also wish to thank everyone for your patience during the move.

HP certified earlier this month Cluster Resources' Moab Cluster Suite on its XC Clusters, providing customers using the popular Linux-based XC cluster with a comprehensive and simple workload management and scheduling solution. The certification confirms that Moab is fully compatible with HP XC Clusters.
"HP has designed a cluster environment that is simple to use, yet powerful, and provides high quality for the price," said Bruce Toal, director, Marketing and Solutions HPC, HP. "When Moab Cluster Suite
is added into the HP XC software stack, users can have greater control over how their resources are utilized and can now have the capability to integrate XC resources into a grid of multiple, possibly heterogeneous, systems and clusters all running different schedulers and grid tools.”
Cluster Resources invites all current and prospective XC Cluster users who are unfamiliar with Moab to learn more here. Any additional questions can be answered by Cluster Resources' support staff at +1 (801) 873-3400. You can purchase Moab Cluster Suite through Cluster Resources or HP. More information about HP XC Clusters is available at www.hp.com/go/clusters.
Cluster Resources is pleased to announce the launch of a research study aimed to discover best practices of the Top500 and other leading supercomputing sites regarding their requests for proposals. The goal of the study is to provide the HPC community with the results to facilitate improved communication and overall satisfaction between customers and vendors.
“As sites look to update and add to their supercomputing resources, finding the best strategies and solutions for their needs can be a difficult task,” said Nick Ihli, Technical Marketing Manager. “We want to provide the supercomputing community with those tools that will aid sites in achieving the greatest return on their investments.”
The study is anticipated to extend throughout the coming year, beginning with academic sites and progressing on to government and commercial sites. Results from the study will be published as each phase is completed.
Organizations who have implemented a grid system connecting their multiple clusters can easily experience job scheduling cycles that slow down the user interface due to randoms bursts of job submissions from one or more end users. The slowdown is a result of the resource manager notifying the scheduler each time a job is submitted. The scheduler, in an attempt to minimize response time, will start a new scheduling cycle to determine if the newly submitted job can run. However, this process slows down the system for two reasons. First, each individual job will be scheduled on a first come first serve basis. Second, a heavy load is placed on the resource manager because it has to contact the scheduler for every job submission and then wait for a response from the scheduler before it proceeds to the next job submitted.
These problems can be resolved by implementing Moab's Job Aggregation Time feature. Job Aggregation Time specifies the minimum amount of time the scheduler should wait after receiving a job event until it should process that event. For example, if a user were to submit 1000 new jobs simultaneously, administrators could specify that Moab would wait a predetermined amount of time between scheduling cycles when job events have been received. This parameter allows sites to process job events in groups decreasing total job scheduling cycles and allowing the scheduler to make more intelligent choices by aggregating job submissions and choosing between the jobs.
