The CaTCaN group is well supported by a diverse range of computing platforms. For development work and pilot calculations the group maintains its own cluster in the School of Chemistry. For more computationally demanding applications the group makes extensive use of the University of Nottingham's High Performance Computing facilities. In addition the group is actively involved in the EPSRC funded MidPlus regional HPC initiative, which helps foster links between industry and academic that make use of HPC facilities.
The CaTCaN group runs two local clusters. Crow, a heterogenous cluster used by the group for development and testing featuring range of different compute machines including intel and AMD linux platforms as well as facilities for Nvidia CUDA computing. A second cluster Hartree is operated by the Teale group and features 120 AMD compute cores with 256Gb of RAM per node. Hartree was established by a Royal Society Equipment grant in 2013.
The University of Nottingham HPC Service: Minerva
The University of Nottingham runs a high-performance computing service, Minerva. This service offers 46 teraFLOPs of computing power to users across the university. The service features high speed parallel Panasas storage as well as specialised high memory nodes and GPU computing nodes. This substantial and flexible resource underpins simulations performed by research groups across the university, including CaTCaN.
The MidPlus Initiative
The MidPlus regional HPC resource was created in January 2012 through a £2M investment in e-Infrastructure from the EPSRC and £1.5M investment from four partners: University of Nottingham, University of Warwick, University of Birmingham and Queen Mary, University of London. The partners share new HPC compute and data services. These resources complement and significantly extend the resources offered by the University of Nottigham Minerva HPC service.
National and European Computing Facilities
For very large-scale applications computing resource can be requested on National and European level supercomputing facilities. This includes Archer the UK's largest supercomputer. These facilities provide access to cutting edge computing resources and training allowing applications at the forefront of today's computational capabilities on a global scale.
