CERN openlab is a unique public-private partnership. It works to accelerates the development of cutting-edge ICT solutions for the worldwide LHC community, as well as wider scientific research. As part of its educational mission, CERN openlab runs a nine-week summer-student programme, with around 40 young researchers selected each year. The students attend a series of lectures, participate in research excursions, and work on ICT projects, gaining hands-on experience with the latest technologies. Together with partner-company Intel, CERN openlab established the Modern Code Developer Challenge. Through this, five of the 2017 summer students were invited to share their work. One lucky winner will be chosen to present their work at the Intel HPC Developer Conference and the SC17 conference, in November.
