Dr Tom Deakin is a Senior Research Associate in the High Performance Computing Research Group at the University of Bristol, led by Professor Simon McIntosh-Smith. Tom is the Chair of the Khronos SYCL Advisory Panel and member of the SYCL Working Group. Tom was a lecturer for Introduction to Computer Architecture at Bristol University in Autumn 2020. Tom completed his PhD in Leveraging Many-Core Technology for Deterministic Neutral Particle Transport at Extreme Scale in 2018, and has since continued working on unstructured mesh transport and performance portability on HPC architectures. In 2012, Tom graduated top of his class from the University of Bristol with first class honours with a MSc in Mathematics and Computer Science, winning the prize for Best graduating student in Computer Science and Mathematics. Tom has been involved in teaching an Introduction to High Performance Computing at the University of Bristol and given tutorials on parallel programming models at international conferences and private courses on OpenCL and OpenMP. Training material on OpenMP for Computational Scientists and HandsOnOpenCL can be found online.
