Welcome to the website for the Unix Systems Group high performance computing operations. USG operates a general purpose cluster computer system designed for use by researchers at the University of Tennessee, Knoxville.
The research compute cluster, commonly referred to as the Newton cluster, is a joint effort between OIT and departments at the UT Knoxville campus to establish a campus research computing environment. The Newton cluster provides a compute environment for general research computing for faculty, staff, and students. The cluster performs functions such as general research computing and also code testing and fine tuning, prior to use at larger computing clusters such as ORNL’s compute facilities.
We have two mailing lists to serve the HPC user community: USG_HPCC for announcements and general interest discussion, and HPC_HELP for individual support requests. Cluster user meetings are on the first Monday of each month: MeetingSchedule.
Announcements
The data backup and "Time Machine" historical file retention system is now online. See DataBackup for how to access your backup data.

We have created a new LSF queue called "testing" which is designed to enable quick testing of parallel code. We have included 2 dedicated machines in this queue with a total processor count of 16 (BatchQueue).

The university has provided funds for us to purchase a 24TB storage server to augment the existing disk-based storage on the cluster. The server is a Sun Fire X4500 (Thumper) and consists of an innovative combination of a 4-core Opteron server and 48 attached SATA hard disks using the ZFS file system for redundancy and performance. We will be making this available for global access on the cluster through NFS shares of various sizes for maximum 6 month durations. Visit StorageApplication to request space on this device.

The cluster is currently back online and operational with the exception of one storage array (/data6). We are currently investigating this problem and with provide further information when it is available. Update: replacement parts for the affected array should be installed on Monday.

There will be power outage in the early morning of the July 22nd to do maintenance on the backup power system. The queue will be drained of jobs 24 hours in advance, but if you have a long running job it may be killed. We will take the opportunity to do an upgrade of the Ethernet switch as well.

We are planning a number of changes to the cluster in order to increase ease of use for users and administrators. However, since the cluster is currently in use we will make every effort to minimize interruption to cluster operations. Any changes that will affect end users will be announced via the USG_HPCC mailing list.
