The Iridis Compute Cluster
The current Iridis 3 is our third generation cluster and is one of the largest computational facilities in the UK. Iridis provides High Performance Computing facilities in a professionally managed service environment and is available to the University's entire research community.
Access to Iridis
Iridis is primarily designed as a batch service for users who need to run either distributed memory parallel jobs, or multiple resource-intensive sequential jobs. If you are a researcher or postgraduate student and think that you have a good case for using Iridis, please fill in the online application form.
Iridis received an upgrade to 924 nodes in March 2012 and now comprises:
- 924 Intel Westmere compute nodes, each with two 6-core processors;
- 84 Intel Nehalem compute nodes with two 4-core processors;
- 11760 processor-cores providing over 105 TFlops peak;
- Standard compute nodes have 22 GB of RAM per node;
- 32 high-memory nodes with 45 GB of RAM per node;
- All nodes are connected to a high speed disk system with 110 TB of storage;
- All nodes are connected to an InfiniBand network for interprocess communication;
- Cluster is accessed via advanced scheduling and management system from Adaptive Computing;
Acknowledging the use of IRIDIS
When preparing a publication describing work that involved usage of Iridis, please ensure that you reference the Iridis cluster. Such recognition is important for acquiring funding for the next generation hardware, support services, data storage and infrastructure. The following text is suggested as a starting point. Please, feel free to augment or modify as you see fit.
''The authors acknowledge the use of the IRIDIS High Performance Computing Facility, and associated support services at the University of Southampton, in the completion of this work.''
In addition, we kindly ask you to notify us of any report, conference papers, journal article, theses which contain results which were obtained on Iridis by sending an email to email@example.com
