HPC-SIG Meeting, 21th – 22nd May 2025, Cambridge

Meeting convened in the fantastic West Hub in sunny Cambridge. The meeting was very well attended by over 50 delegates from across UK institutions, as well as the same number of online participants. A wide range of topic were covered with a focus on the bleeding edge of HPC at the University of Cambridge and the DAWN data centre. The meeting was a great success and we would like to thank all the speakers and delegates for their contributions, as well as the University of Cambridge for hosting us.
