The research group Formal Methods and Tools at the University of Twente (Enschede – The Netherlands) is looking for a PhD researcher (4 years) to work on the EU Strep project CARP (Correct and Efficient Accelerator Programming), funded by the European Union.
Within the context of the CARP project, the PhD student will work
in particular on:
– requirements analysis for accelerator programming
– the formal semantics of an intermediate programming language for
describing accelerator algorithms
– developing logic-based verification techniques for this intermediate
programming language, taking into account common accelerator programming
In recent years, massively parallel accelerator processors, primarily
GPUs, have become widely available to end-users. Accelerators offer
tremendous compute power at a low cost, and tasks such as media
processing, simulation, medical imaging and eye-tracking can be
accelerated to beat CPU performance by orders of magnitude. Performance
is gained in energy efficiency and execution speed, allowing intensive
media processing software to run in low-power consumer devices.
Accelerators present a serious challenge for software developers. A
system may contain one or more of the plethora of accelerators on the
market, with many more products anticipated in the immediate future.
Applications must exhibit portable correctness, operating correctly on
any configuration of accelerators, and portable performance, exploiting
processing power and energy efficiency offered by a wide range of devices.
The overall aims of CARP are to design techniques and tools for correct
and efficient accelerator programming:
– Novel & attractive methods for constructing system-independent
– Advanced code generation techniques to produce highly optimised
system-specific code from system-independent programs
– Scalable static techniques for analysing system-independent and
system-specific accelerator programs, both qualitatively and quantitatively
The PhD candidate we are looking for is expected to work on the
development of tools and techniques for correct accelerator programming.
Within the consortium an intermediate programming language for
accelerator programming will be developed. The PhD candidate is expected
to develop a solid formal semantics for this language, together with
appropriate verification techniques. An important focus of the
verification work is that it will focus on bug finding, without too many
false negatives, rather than on developing full correctness proofs. For
the verification, it is expected that the logical basis will be
permission-based concurrent separation logic. Sometimes the intermediate
programming language will not provide the required efficiency, and
programs will be written in a low-level language as OpenCL. Therefore,
the verification techniques also will be extended to this lower level.
An enthusiastic PhD student with an MSc degree in Computer Science (or
an equivalent qualification). The candidate should have a thorough
theoretical background, a demonstrable interest in program semantics and
verification, and some knowledge about multithreaded programming (in
We are looking for a researcher with an independent mind who is willing
to cooperate in our team. It is understood that he or she works on the
topics listed above, and contributes to the expected deliverables for
the project. Further we ask for good communicative and good
collaboration skills. Candidates should be prepared to prove their
English language skills.
As a research outcome we expect publications, (prototype) tools, and a
