ARCHER is the UK's high-end computing service, funded by EPSRC and NERC. It is available for use by academia and industry in the UK and Europe.

ARCHER is a Cray XC30 machine consisting of 4920 compute nodes. Each node is made up of two 2.7 GHz, 12-core Ivy Bridge processors, and either 64 or 128 GB of memory. This provides a total of 118,080 cores in the system. Nodes are connected through Cray's Aries interconnect technology. ARCHER also provides a serial queue for compilation and other tasks. The file systems are split into:

  • /home: A small backed-up space.
  • /work: A larger region optimised for fast access from the compute nodes. It is intended for temporaray storage of simulation, and is not backed-up.
  • /nerc: The Research Data Facility archive for long term storage. The RDF also has a dedicated processing system - the Data Analytic Cluster (DAC).

For more information about the ARCHER service, including the hardware and software available see the webpage:


UMUI based UM versions installed on ARCHER are: 6.1, 6.6.3, 7.3, 7.8, 8.2, 8.4, 8.5, 8.6

Rose/Cylc based UM version available include the 10.x and 11.x series.

For all UM versions, whether using the UMUI or Rose, runs are submitted via PUMA.
