​In order to create the CIUK programme we include a mix of invited presentations selected by the CIUK Scientific Advisory Committee and those selected from a call for presentations and evaluated by the CIUK Programme Committee. The standard of application received from our call for presentations was exceptionally high this year and that made the evaluation process very difficult. We received three times as many applications as spaces on the programme and they were all very interesting. However, we have now finalised the selection process and there is general consensus amongst our committee members that this is the strongest CIUK programme we have had in over thirty years. 

To view the recordings of the individual presentations please follow the links in the programme below.
Please note: the file sizes are quite large and the recordings make take a short time to load.

“Heterogeneous Computing: past, present and future”

ABSTRACT: Heterogeneous computing has been a part of HPC almost since the field began, but the current wave, which began 15 years ago, is the most significant revolution in the field since the commodity cluster. In this talk we will explore where this trend has come from, discuss its implications, and consider how our community needs to act in order to be ready for the era of heterogeneous Exascale supercomputers. We will also discuss related initiatives in the UK, such as ExCALIBUR and the UK’s Exascale programme.

BIO: Simon McIntosh-Smith is Professor of HPC at the University of Bristol, UK. He began his career in industry as a microprocessor architect, first at Inmos and STMicro in the 1990s, before co-designing the world's first fully programmable GPU at Pixelfusion in 1999. In 2002 he co-founded ClearSpeed Technology where, as Director of Architecture and Applications, he co-developed the first modern many-core HPC accelerators, which lead to the creation of the first modern heterogeneous supercomputers, such as Tsubame 1.0 at Tokyo Tech in 2006. He now leads the HPC Research Group in Bristol, where his research focuses on advanced computer architectures and performance portability. He leads the Isambard supercomputer service which combines Arm-based CPUs with a diverse range of CPUs and GPUs from all the main vendors.
