Cirrus is a state-of-the-art HPC system running industry-standard Linux that provides an ideal platform for users to solve their computational simulation and modelling challenges.

Users are able to run their own codes as well as accessing a range of commercial software tools. These are accessed on an on-demand, pay-per-use basis and used to solve CFD and FEA simulation and modelling problems in sectors such as automotive, aerospace, energy, oil and gas, general engineering, life sciences and financial services.

This short video shows how users can easily access HELYX, a CFD package for engineering analysis & design optimisation produced by ENGYS, from their desktop. 

The system

Cirrus is a state-of-the art SGI ICE XA system with 280 compute nodes, utilising a superfast Infiniband interconnect.

There are 36 cores per node (18 cores per Intel Xeon “Broadwell” processor) providing 10,080 cores in total. Hyperthreading is enabled on each node providing a total of 72 threads per node. Each node has 256GB RAM. Three login nodes, with similar hardware and software environment to the compute nodes, are provided for general use.

Local Lustre storage is provided by a single Lustre filesystem with 406 TB of disk space and users will have access to EPCC's considerable data storage and archiving services.

The system is housed at EPCC’s Advanced Computing Facility at Easter Bush.


On-demand industrial access on Cirrus is charged at £0.0369 per core hour (exclusive of VAT).
