Safety-related challenges and opportunities for GPUs in the automotive domain
GPUs have been shown to cover the computing performance needs of autonomous driving (AD) systems. However, since the GPUs used for AD build on designs for the mainstream market, they may lack fundamental properties for correct operation under automotive's safety regulations. In this paper, we analyze some of the main challenges in hardware and software design to embrace GPUs as the reference computing solution for AD, with the emphasis in ISO 26262 functional safety requirements.Authors would like to thank Guillem Bernat from Rapita Systems for his technical feedback on this work.

Ethical and Social Aspects of Self-Driving Cars
As an envisaged future of transportation, self-driving cars are being
discussed from various perspectives, including social, economical, engineering,
computer science, design, and ethics. On the one hand, self-driving cars
present new engineering problems that are being gradually successfully solved.
On the other hand, social and ethical problems are typically being presented in
the form of an idealized unsolvable decision-making problem, the so-called
trolley problem, which is grossly misleading. We argue that an applied
engineering ethical approach for the development of new technology is what is
needed; the approach should be applied, meaning that it should focus on the
analysis of complex real-world engineering problems. Software plays a crucial
role for the control of self-driving cars; therefore, software engineering
solutions should seriously handle ethical and social considerations. In this
paper we take a closer look at the regulative instruments, standards, design,
and implementations of components, systems, and services and we present
practical social and ethical challenges that have to be met, as well as novel
expectations for software engineering.Comment: 11 pages, 3 figures, 2 table
Grand Challenges of Traceability: The Next Ten Years
In 2007, the software and systems traceability community met at the first
Natural Bridge symposium on the Grand Challenges of Traceability to establish
and address research goals for achieving effective, trustworthy, and ubiquitous
traceability. Ten years later, in 2017, the community came together to evaluate
a decade of progress towards achieving these goals. These proceedings document
some of that progress. They include a series of short position papers,
representing current work in the community organized across four process axes
of traceability practice. The sessions covered topics from Trace Strategizing,
Trace Link Creation and Evolution, Trace Link Usage, real-world applications of
Traceability, and Traceability Datasets and benchmarks. Two breakout groups
focused on the importance of creating and sharing traceability datasets within
the research community, and discussed challenges related to the adoption of
tracing techniques in industrial practice. Members of the research community
are engaged in many active, ongoing, and impactful research projects. Our hope
is that ten years from now we will be able to look back at a productive decade
of research and claim that we have achieved the overarching Grand Challenge of
Traceability, which seeks for traceability to be always present, built into the
engineering process, and for it to have "effectively disappeared without a
trace". We hope that others will see the potential that traceability has for
empowering software and systems engineers to develop higher-quality products at
increasing levels of complexity and scale, and that they will join the active
community of Software and Systems traceability researchers as we move forward
into the next decade of research
