Energy Efficient Computing Workshop

Monday and Tuesday 15-16th September

Rutherford Appleton Laboratory

The Computational Mathematics Group from STFC's Scientific Computing Department is organising a workshop on Energy Efficient Computing. All are very welcome to attend but registration is mandatory.

The 2-day workshop is primarily aimed at software development teams embedded within CoSeC communities but is also suitable for wider audiences. The sessions will revolve around four key themes: Qualitative Algorithms, Community, Hardware, and Quantitative Practice and will be designed to share knowledge and start conversations around making energy-efficient choices.

Invited speakers

  • Wes Armour (Oxford University, UK)
  • Grey Ballard (Wake Forest University, USA)
  • Laura Grigori (EPFL - PSI, Switzerland)
  • Martin Juckes (STFC, UK)
  • Loic Lannelongue (University of Cambridge, UK)
  • Hatem Ltaief (KAUST, KSA)
  • Théo Mary (LIP6, Sorbonne University, France)
  • Kirsty Pringle (Software Sustainability Institute, The University of Edinburgh, UK)
  • Andy Turner (EPCC, University of Edinburgh, UK)
  • Garth Wells (Cambridge University, UK)
  • Zeyu Yang (Oxford University)

Registration

All are welcome, and there is no registration fee for attendance, but registration is mandatory - registration DEADLINE: 1st September 2025. Please register using this registration form.
Please bring a valid ID (BRP, Passport, Driving Licence, etc) to allow you onto the RAL site.
 
We will go out for dinner in the early evening of Monday. Attendees will pay for their meal. Please indicate on the form whether or not you'd like to join us when registering so we have a rough idea of the numbers.
 

Location

The postcode for the Rutherford Appleton Laboratory is OX11 0QX.

The nearest train station is Didcot, and the Thames travel X24/X34/X35 buses travel between Didcot Parkway Station and the Harwell Campus (~ 30 minute journey, with a bus every ~ 15 minutes). Taxis are also available at Didcot Parkway Station.

Detailed travel instructions are provided on the STFC "How to Find Us" page. The official website for the bus service can be used to plan your journey.

Talks will take place in the Pickavance Theatre building R22 on the main Rutherford Appleton Laboratory site. On arrival, please report to reception and they will direct you to the Pickavance Theatre. If driving, reception will direct you to a suitable place to park.
