Portrait of Simon Cooksey

Simon Cooksey

Research Fellow in Programming Languages


I am in the PLAS research group. My specific research interests are on the semantics of systems programming languages. I am currently working on porting the Rust programming language to the Morello platform. My other work is on improving the specification of the memory consistency model of C/C++ and I have on-going collaboration with ISO C++ committee.

Internship at NVIDIA

As an intern at NVIDIA I extended the Memory Consistency Model for NVIDIA's virtual instruction set (PTX) to support ``memory proxies''. This enables writing well defined programs which mix generic load and store operations with specialised load and store operations for texture, surface and constant accesses.

If you are a PhD Student who is interested in what an internship can offer for your research, feel free to email me and ask questions.

Research interests

I am a member of the following research groups:
