Rethinking Compilation

A 5 lecture course delivered at ACACES 2023 investigating new compiler approaches for a heterogeneous world. Topics covered include machine learning, equality saturation, program embeddings, graph neural networks, neural program synthesis, neural machine translation and large language models.

PhD positions

I am interested in recruiting students in any of the areas covered by my research interests or current projects. I am also open minded - if you have a great idea you would like to pursue - get in touch!

Research Interests

The primary research questions I am interested in are: (i) how can compiler technology best exploit the potential of high performance heterogeneous architectures (ii) how can we best design high performance heterogeneous to meet emerging applications.

My research interests include:

  • Heterogeneous Code discovery and Optimisation. I am interested in how we can use diverse techniques including constraint analysis, program synthesis and machine learning to discover code patterns that match heterogeneous hardware and automatically tune them.
  • Neural Machine Translation and Neural Synthesis I am interested in how transformer based models can aid translation from one programming language to another and how program behaviour can be exploited to drive automatic synthesis of high level code.
  • Deep Neural Network system stack. I currently investigate how to optimise deep learning training and inference based on real world device constraints. I am interested in a cross-stack approach incorporating Bayesian Optimisation at the model layer and a device specific optimisations at the hardware layer to unify neural architecture search and program transformation.
  • Software Defined Hardware. I currently investigate how to map languages such as Python to flexible hardware (e.g. coarse-grain reconfigurable architectures). I am interested in both how software may be adapted to fit hardware and hardware reshaped for software.
  • Auto-parallelising compilers. I am currently investigating the use of dynamic, probabilistic analysis in conjunction with machine learning to develop a new approach that gives future proof scalable code for multi-cores.
  • GPGPU multi-core platforms. I am interested in how we can use smart compiler analysis and adaptation to exploit the potential of such architectures for compute and graphics workloads.
  • Machine learning based optimisation. I'm interested in how predictive modelling and feature generation can be used to automate the design of compilers
  • Compiler/Architecure co-design space exploration. We are investigating the use of predictive models to predict the best compiler optimisations for any architecture
  • Very High level programming languages. I am interested in how languages such as Matlab, which provide great expressive power may be implemented on multi-cores
