STFC's Scientific Computing Department has over thirty years' experience in the design, implementation and development of world leading scientific software. It is internationally recognised as a centre for parallelisation, optimisation and porting of existing software to leading edge and novel architecture systems. In addition to domain expertise in a wide range of disciplines the Department also has strong software engineering and numerical algorithms expertise.

Following recent capital investments from UK government the Department has established the Hartree Centre in collaboration with IBM. This outward facing centre offers a range of services including collaborative software development and access to a range of novel hardware platforms (98,304 core Blue Gene/Q, Blue Gene Active Storage, iDataPlex, NextScale, ARM, nVidia Tesla GPU, Intel Phi and Maxeler MPX-X).

For access to the Hartree Centre machines and support in your research projects, please contact: David Holder, Head of Programme Support Office, The Hartree Centre, STFC Daresbury Laboratory, WA4 4AD: e-mail:; tel: 01925 603120.

Phase-1 Computer Systems

The Hartree Centre has a heterogeneous collection of computational, storage, and networking resources. Each resource is designed to fulfill a specific requirement in the field of high performance and scientific computing, and using the right resources for each task is an essential part of getting the most out of any project.

Procurement in early 2012 included refurbishment of the existing HPCx computer room at Daresbury Laboratory. It is now split into two to form a state-of-the art data centre, half with water cooling, and half with conventional air cooling.

Phase-1 computer systems were Invicta (aka Blue Wonder), Bantam and Bifort (aka Blue Joule). These have now been de-commssioned to make way for more efficient and highly performing architectures.

Phase-2 Computer Systems

There is a Flash time-lapse video showing the installation during March 2014 here: external link: .

The login cluster for Iden and Napier is named Calcott.

Iden - iDataPlex and Xeon Phi Cluster (Blue Wonder Phase-2)

Napier - NextScale Cluster (Blue Wonder Phase-2)

Scafell Pike

This was installed in the HDR. It included 22 racks and 80+ pallets of equipment with water and electrical hook ups. The Impact & Engagement team are arranging time lapse footage of the installation for sharing at a future date.


The Joint Academic Data Science Endeavour (JADE), an NVIDIA DGX-1 system owned by the University of Oxford and run as part of a Tier-2, EPSRC-funded consortium has been installed at the Hartree Centre. We will host and support the system in partnership with Atos, who are providing the hardware. JADE will be the largest GPU facility in the UK supporting world-leading research in machine learning.

If you would like to organise an event at the Hartree Centre such as a workshop, training course or tour then please see external link: where there is a link to an Event Proposal Form. Visualisation suites and Brunner-Mond can also be booked via this form or you can send an email to the Hartree Centre Service Desk at

A list of events can be seen on the STFC Events Booking page at: external link:

Visualisation Suite

The visualisation suite comprises two parts: the Surround Wall (or Curved Wall) in the Leverhulme room; and the Quad Wall in the Crosfield room, which is adjacent to the training suite. These facilities support full 3D active stereo and a wide range of visual applications.

For more information, see here: external link: .

Training Suite

The training suite in the Brunner-Mond room consists of several rows of desks with a total of around 50 workstations. There are two presenters' areas with separate workstations and projectors onto wall mounted screens. This is primarily designed as an area for hands-on computer based training. There are separate facilities for seminars, lectures and workshops.
