Lecturer in Advanced Computer Systems

University of Bristol


Dr Tom Deakin is a Lecturer in Advanced Computer Systems at the University of Bristol. Tom is part of the High Performance Computing Research Group, led by Professor Simon McIntosh-Smith. Tom’s work includes researching the performance portability of massively parallel High Performance simulation codes. Tom is the Chair of the Khronos SYCL Advisory Panel, SYCL Outreach Officer and member of the SYCL Working Group. 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 lectures for Computer Architecture and High Performance Computing at the University of Bristol, and has 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.
