SYCL Failure Taxonomy Internship

Codeplay is known for being one of the leaders in the development of the SYCL™ standard and recently Codeplay has kick-started the design of SYCL SC, a version of SYCL targeted at safety-critical industries. In these industries, such as automotive, avionics, nuclear and rail, safety is paramount, because a bug in the software could lead to people being hurt. To be able to write safe, bug-free SYCL code engineers have to be well trained in the SYCL programming model. This means they need to not only need to learn how to write SYCL code, but also to anticipate pitfalls and sources of errors. To complement the existing SYCL tutorials and samples, we are looking to create a set of negative tests and to organise them into a failure taxonomy. However, instead of interface tests that misuse the SYCL API, the focus is on applications that compile without errors but fail at runtime, perhaps even non-deterministically, or only on specific types of hardware.

In addition to educating users about how NOT to write SYCL code, these tests can be incorporated into the test suites for the runtime, to ensure that the implementation handles the errors gracefully as far as possible. Error handling is a very important feature of software in a safety-critical context and has to be extensively tested to ensure that errors are caught and dealt with, which is why negative testing is essential to ensure the safety of this kind of software.

Also, if analysis shows that certain SYCL features are more likely than others to lead to errors, it might suggest that these should be removed from the upcoming SYCL SC specification, if possible.

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 3-6 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.

Responsibilities

  • Research and brain-storm the different ways a SYCL program can compile, but fail/crash/hang. Some failure modes may only present on certain devices, e.g. CPUs/GPUs/DSPs.
  • Develop an organised, categorised set of SYCL tests that (may) fail, according to the specification.
  • Analyse the failure modes to categorise them, writing up the taxonomy of failing tests in a document.
  • Write a minimal SYCL test for each, describing the type and reason for failure in the comments.
  • Prepare a blog post and/or presentation describing the effort and its results.

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.

  • Modern C++ experience
  • Experience writing applications for SYCL, OpenCL or CUDA

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 the differences between CPUs, GPUs, DSPs, etc.
