The Isambard service collaborates with Bath, Bristol and Cardiff universities to create a network of computational researchers. The University of Bath is very excited to collaborate with GW4 in this project and believes that collaboration allows larger and more complex research to be experimented with and explored quicker and more securely. The collaboration will be an opportunity to expand the existing computational research community and develop a network of HPC users. The Advancing Research Computing Department are developing workshops to get students and academics started on using Isambard very soon.
The GW4 Alliance, together with Cray Inc. and the Met Office, has been awarded £3m by EPSRC to deliver a new Tier 2 high performance computing (HPC) service for UK-based scientists. This unique new service, named ‘Isambard’ after the renowned Victorian engineer Isambard Kingdom Brunel, will provide multiple advanced architectures within the same system in order to enable evaluation and comparison across a diverse range of hardware platforms. Isambard is a HPC service provided by GW4 and the UK Met Office. The system is funded by EPSRC and is one of six Tier-2 HPC facilities in the UK.
Isambard is a Cray XC50 system which comprises 10,496 cores and is one of the world's first production Arm-based supercomputers. Each of the 164 compute nodes contains two 32-core Cavium ThunderX2 processors running at 2.1 GHz and has 256 GB of DDR4-2666 memory. The nodes are connected via Cray Aries interconnect with a Dragonfly topology. A Cray Sonexion 3000 storage cabinet provides 480 terabytes of Lustre storage.
