Stuttgart (DE) hosted the HiPEAC Computing Systems Week from Oct 25 to Oct 27, 2017. Considering that in Stuttgart are located large automotive companies, such as Bosch, Daimler, and Porsche, and about 1500 SMEs, the focus of this event was on mobility. Mobility is of crucial interest for computing community in Europe. According to Sandro D’Elia, Programme Officer in the Technologies and Systems for Digitising Industry Unit of the EC DG CONNECT, in 2022 an average car will comprise electronic components worth € 6000. The trend towards cooperative and autonomic mobility poses many Big Data challenges that we need to address in the upcoming period. Therefore, five European projects (CHIPSET, Mobility4EU, SISSDEN, OPTIMUM, BalticSatApps) and a large Swedish company (Södra) met in Stuttgart to discuss about “Big Data in Mobility and Transport.” Presentations of participants highlighted various complementary aspects including, computer science methods and infrastructures for Big Data, visions for future of mobility in Europe, security aspects, and multi-modal vehicle routing optimization. During discussion we discovered areas for future cooperation, and future dialogue between participants (such as, AIT and Sördra) was planned. We are grateful to HiPEAC for providing an excellent meeting infrastructure. We thank all presenters and hope to come back to the HiPEAC CSWs in the future.
