RISC-V Simulator and OpenCL Integration Internship

Codeplay has a software platform called Acoran, that is designed to support C++ programming on a wide-range of hardware devices.  These devices include some RISC-V targets and simulators, in this project we would like to add support for an additional academic multi-core RISC-V simulator.  This project should allow us to test higher RISC-V core counts on a simulator than has previously been possible – this is of particular interest for the kind of massively-parallel programming models that Codeplay specializes in.  Also, this simulator uses 32-bit RISC-V cores, our previous RISC-V work has targeted 64-bit cores.

The Acoran platform includes an implementation of the heterogeneous C++ programming standard SYCL, ComputeCpp, and a toolkit for running that on new devices via OpenCL or Vulkan, ComputeAorta.  ComputeAorta does this by providing well-documented internal interfaces.  This project will involve porting those interfaces to the new RISC-V simulator; using existing test-suites to determine the completeness of the simulator and implementation pair; and creating a demonstration for the new port.

Please Note: Due to COVID-19 we are following the Scottish Government Roadmap and, although we are operating normally, we have not yet returned to the office.

The successful candidate should be able to work from home for the duration of the office closure. The position is a temporary internship. The successful candidate must be able to demonstrate the existing right to work in the UK.

Although this internship is on offer for a duration of 3 months, we are delighted to accept applications for longer internships and many of our interns have stayed with us to do university placement years or have become permanent members of our team.


  • Understand how ComputeAorta's internal interfaces work.
  • Port of boot code required to boot a program on the new simulator.
  • Create a new implementation of the simulator shim, tested on existing internal testsuites.
  • Run OpenCL and SYCL testsuites on top of simulator, documenting pass rates and areas of failures.  100% pass rate is not required inside this internship.
  • Choose some interesting demo application, e.g. SYCL-ONNX, that should work on the new simulator and resolve any issues stopping it from running.
  • Potentially, aid in improving our documentation for porting our software to new simulator or hardware targets.

What We Offer

Codeplay is internationally recognized as being at the forefront of software development technology. Working at Codeplay offers unique opportunities and challenges to learn new technologies and to get involved in shaping the software industry. Codeplay's projects range from: creating tools and tool sets (optimizing compilers, debuggers, profilers, programming models & APIs, test systems/suites, etc.) for brand-new unannounced next-generation hardware; developing and optimizing current machine learning (TensorFlow™) and computer vision applications; research and development into lowering the power consumption of mobile devices; and contributing to new programming models and software standards (e.g. C++, SYCL™, OpenCL™, Vulkan® and SPIR™-V).

Codeplay Software is a world pioneer in enabling acceleration technologies used in AI, HPC and automotive. Codeplay was established in 2002 in Edinburgh, Scotland and developed some of the first tools enabling complex software to be accelerated using graphics processors. Today, most AI software is developed using graphics processors designed for video games, and more recently specialised AI and computer vision accelerators. Codeplay continues to work with global technology leaders to make the latest complex AI systems programmable using open-standards based programming languages and allows application developers to quickly bring software to the market.  Codeplay is also deeply involved with the definition of open standards, especially OpenCL™, SPIR™, SYCL™, and Vulkan™ through The Khronos Group, and MISRA C++ for automotive.

  • A friendly and relaxed working environment where colleagues respect and support each other.
  • Learn from experienced colleagues: our staff frequently give company-wide knowledge-sharing presentations on new software and technology trends, personal projects and other relevant subjects.
  • Great career prospects within a growing company
  • Newstart mentoring scheme
  • Flexible working hours
  • Frequent company social events (social nights, pot luck lunches, gaming, karting, outdoor adventures, and more) (Post-COVID!)

Required Skills

The ideal candidate is a self-motivated individual who can work through a problem from start to finish, meet deadlines as required to support software projects, and has the ability to work under pressure. You will be working on technology that is seldom announced to the public and could be several years away from public release, so confidentiality is critical. You should be able to work both independently and collaboratively within teams of varying skill sets and expertise. You should be welcoming towards, and able to adapt to, the introduction of new technologies, responsibilities and projects, as Codeplay works with cutting-edge technology and takes on a diverse range of projects.

  • Excellent programming skills.
  • Some level of C++ experience.
  • Some level of experience working with large code-bases.
  • A keen interest in systems programming, e.g. compilers, simulators, emulators, operating systems, etc.
  • A desire to work within a small and focussed team.
  • Excellent written and spoken communication skills.

Beneficial Skills

Knowledge and/or experience of any of the following would be useful for the role, but are not essential. You must be able to learn new skills, but will be given support from Codeplay's team to get you up to speed.

  • Coursework or experience involving compilers or assembly, such as a compiler or computer architecture course.
  • Any form of low-level or systems programming, e.g. operating systems, development on embedded boards, etc.
  • Knowledge of OpenCL or SYCL, or any other parallel programming model.
  • Experience with build automation tools, such as CMake.
  • Experience with testing software, whether writing new tests or making using of existing test-suites.
