This library is built on the unique Julia infrastructure for transpiling code to GPU backends, and years spent developing the JuliaGPU ecosystem that make it a joy to use. In particular, credit should go to the following people and work:

  • The Julia language design, which made code manipulation and generation a first class citizen: Bezanson J, Edelman A, Karpinski S, Shah VB. Julia: A fresh approach to numerical computing. SIAM review. 2017.

Much of this work was possible because of the fantastic HPC resources at the University of Birmingham and the Birmingham Environment for Academic Research, which gave us free on-demand access to thousands of CPUs and GPUs that we experimented on, and the support teams we nagged. In particular, thank you to Kit Windows-Yule and Andrew Morris on the BlueBEAR and Baskerville T2 supercomputers' leadership, and Simon Branford, Simon Hartley, James Allsopp and James Carpenter for computing support.
