SYCL is a C++-based heterogeneous programming standard for accelerator computing and oneAPI is an open-source ecosystem that includes SYCL support and library integration. The oneAPI framework provides a full stack of compilers, runtimes, libraries and tools for developing heterogeneous applications for various different domains. Within that framework Codeplay implements and maintains support for SYCL on NVIDIA and AMD GPUs. A big part of this effort is optimizing the SYCL compiler such that the generated code has comparable performance to the native CUDA and HIP compilers. This internship will involve identifying areas where applications are not matching native performance due to missing compiler optimizations, and then creating implementations of those optimizations in the NVIDIA and AMD LLVM compiler backends.

The ideal candidate will be someone who has a strong interest in compilers and/or performance optimizations, and who is able to progress on tasks autonomously while sharing progress or blockers with their team.

This internship is on offer for a duration of 3-6 months. Although we usually offer internships for the summer, we are delighted to accept applications for longer or shorter internships and many of our interns have stayed with us to do university placement years or have become permanent members of our team.

The position is temporary and will be based at our head office in central Edinburgh. The successful candidate must, by the start of their employment, have successfully obtained the right to work in the UK.

Starting salary - Competitive & Negotiable

Responsibilities

You will:

• Work as part of a development team supporting oneAPI on NVIDIA and AMD GPUs.
• Work on the implementation of SYCL on NVIDIA and AMD targets.
• Learn about SYCL, DPC++, Clang, and LLVM from experienced engineers.
• Design and implement compiler optimizations for the DPC++ compiler such as function inlining, loop unrolling, code generation and diagnostics.
• Contribute patches to the DPC++ project or upstream LLVM.
• Follow and contribute to performance guidelines for targeting NVIDIA and AMD GPUs with DPC++.
• Build and run SYCL benchmarks as part of an iterative process to evaluate the performance of DPC++ and the impact of any improvements.
• Identify possible additional benchmarks for evaluating the performance of DPC++, with the support of the rest of the team.

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)

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.

• C++ development experience.
• Some level of compiler experience, e.g. coursework or research project.
• Good written English and communication skills.
• Working knowledge of source control and configuration management tools.

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.

• Knowledge of Clang or LLVM.
• Knowledge of NVPTX or AMDGCN.
• Knowledge of heterogeneous programming, e.g. CUDA, SYCL, OpenCL, etc.
• Knowledge of parallel architectures, such as GPUs.
• Knowledge of build systems (e.g. CMake) and compiler tool-chains.
• Experience working in a team.
