Welcome to the website for the Newton HPC Program.
The Newton program is a joint effort between the Office of Research, the Office of Information Technology, and the departments of the University of Tennessee to establish a campus research computing environment.
We operate a general purpose cluster computing system designed for use by researchers at the University of Tennessee, Knoxville.
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.
Our mailing list USG_HPCC provides announcements and general interest discussion for Newton users. For support requests, please contact the OIT help desk at 974-9900 or at http://help.utk.edu/. Cluster user meetings are on the first Monday of each month: Meeting Schedule.
Announcements
We are preparing to soon shut down the old cluster head node newton.usg.utk.edu. If you still require use of this machine, please notify us as soon as possible so that we can make arrangements for you. The tentative date for shutdown will be Wednesday, May 6th.

We are planning to transfer 112 CPUs of the CMRG group to the new Newton cluster on March 1st at 4:00PM. Jobs running on these machines should be stopped or checkpointed before this time. Once the machines are installed in the new cluster and proper operation is verified, we will increase the priority of the CMRG group on the new cluster and announce the availability of the machines. This should take no more than a few hours.

There is a power outage and maintenance period planned from Saturday,
Oct. 11th at 6:00 AM to Monday, Oct. 13th at 12:00AM. We will be taking
advantage of this time to upgrade the Ethernet and Infiniband networks. Please take
appropriate measures to avoid loss of compute progress on your jobs.

The data backup and "Time Machine" historical file retention system is now online. See Data Backup 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 (Batch Queue).

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 Storage Application 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.
-- Gerald Ragghianti - 12 Jul 2007
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.
