Find out more about our research computing service


The PEARL service, provided through a collaboration between The Alan Turing Institute and Science and Technology Facilities Council, is a state-of-the-art GPU-based system for AI and machine learning research. The system includes two NVIDIA DGX2 nodes, and a 600TB storage, linked by a fast interconnect. The system has several thousands of GPU cores, and a large amount of memory to support most AI or machine learning operations, such as training on large datasets. You can see the full specs of the system below.

The system was commissioned in 2019 through The Alan Turing Institute's AI for Science and Government programme and hosted by the Rutherford Appleton Laboratory, Science and Technology Facilities Council.

The system is accessible only to researchers of The Alan Turing Institute, Science, Technology Facilities Council and their collaborators, for research falling under the AI for Science theme.

PEARL is only available for scientific and academic research purposes, and primarily intended for The Alan Turing Institute and STFC staff, and in some cases their collaborators. Access to PEARL is different depending on whether you are a member of staff at STFC/The Alan Turing Institute or an external collaborator, and this will be verified.

For Turing and STFC staff access please fill in the application form below, and once approved we will contact you.

If you are not a member of the Turing or STFC, you will have to contact your collaborator at the Turing or STFC, prior to submitting the form.
