Timely access to detailed climate change scenarios is particularly vital
in developing countries, where economic stresses are likely to increase
vulnerability to potentially damaging impacts of climate change. In
order to help address this need the Met Office Hadley Centre has
developed PRECIS, a regional climate modelling system which can be run
on a personal computer (PC). The aim of PRECIS (Providing Regional
Climates for Impacts Studies) is to allow developing countries, or
groups of developing countries, to generate their own national scenarios
of climate change for use in impacts studies. This will allow transfers
of technology and ownership resulting in much more timely and effective
dissemination of expertise and awareness than if results are simply
handed out from climate model experiments run in developed countries. In
addition, countries using PRECIS are in a better position to validate
the model using their ownhistorical meteorological observations

It then goes on to discus installation having pre-installed Linux and
Fortran (Intel).

In another mention for Linux we have this take from "MOSAC and SRG
Meetings 2015" :-

Introduction:
At the time of MOSAC/SRG last year, we had just secured funding for a
major investment in HPC and signed a contract with Cray. We outlined the
plans for a staged implementation of the new supercomputer, and the
broad shape of how we planned to exploit it scientifically. Huge amounts
of work this year have gone in to the technical implementation,
culminating in the successful operational transition from the IBM to
Phase 1a of the Cray in August. This excellent progress – and further
refinement of our science plans – means that we believe that we are well
placed to exploit the major enhancements in capability that will come
over the next 18 months.
Implementation
Phase 1a of the Cray (1088 Cray XC40 nodes, with Intel Haswell
processors) provides, as expected, broadly like-for-like performance
relative to the IBM which it replaced. Operational transition on August
25th was achieved comfortably ahead of the deadline of the end of the
IBM contract. It is split across the two existing computer halls, and
includes the collaborative MONSooN system (jointly funded by the Met
Office and NERC) which has proved so valuable in enabling joint work
with academia.
Timelines and expectations for Phases 1b and 1c remain as described last
year. Phase 1b will expand the existing 1a systems (with Intel Broadwell
processors) to give around a x6 uplift in compute capacity in March
2016. Phase 1c will follow a year behind, and take the total increase
relative to the IBM to around x15. It will be located on Exeter Science
Park (just across the motorway), and works on the new IT hall and
collaborative space have commenced.
In parallel we have been working on the required developments to the
downstream systems, commensurate with the HPC enhancements. The mass
archive is currently being upgraded, with a Phase 2 further upgrade
planned for early 2017. By 2020 we envisage a more than 10-fold increase
in the total size of the archive (currently 32 PB in each hall). In
parallel, the Scientific Processing and Intensive Compute Environment
(SPICE) project will deliver a replacement of the existing Enterprise
Linux Server hardware and associated storage capabilities, and a radical
change in middleware and toolsets that will enable science to perform
more efficiently by making better use of available compute and storage
resources. The intent is the provision of a highly capable and scalable
compute installation which will enable a range of non-HPC scientific
data processing, including capability for post processing of model
outputs, research and development activities, collaborative work and
routine administration including code building and the preparation of
data for visualisation. Phases 1 and 2 are planned to be operational in
March 2016 and March 2017 respectively, and their design has benefited
significantly from close links to the NERC JASMIN facility.

Do you know what they use if for? Probably not for weather forecasting
algorithms.
