       On 30 September – 4 October, 2019, Montenegro (Budva) hosted the regular JINR 27th
Symposium on Nuclear Electronics and Computing - NEC'2019. The symposium has been held since
1963. The organizers of the Symposium are JINR and CERN.

         All previous forums of this series were highly appreciated at their true value by the leading
specialists and companies involved. The information technologies make a significant contribution to the
automation of the physical experiment. The symposium topics covers the hybrid fields of research at the
junction of detector electronics and computer science, and they are significant interest to the scientific
community. Thus, NEC’2019 scientific program covered a wide range of issues and included the
following sections: Computing for Large Scale Facilities (LHC, FAIR, NICA, SKA, PIC, XFEL, ELI,
etc.); Distributed Computing. GRID & Cloud Сomputing; Research Data Infrastructures; on Detector &
Nuclear Electronics; Triggering, Data Acquisition, Control Systems;; Machine Learning Algorithms and
Big Data Analytics; Computations with Hybrid Systems (CPU, GPU, coprocessors) and the traditional
topic ̶ Innovative IT Education.

        The Symposium attracted more than 190 leading specialists in the field of advanced computing
and network technologies, distributed computing as well as GRID and cloud computing and nuclear
electronics from 13 countries and 30 institutions. In total, 32 sessions were held, the conference
participants heard 31 plenary and 109 sectional talks.

       Financial support for the conference was provided by the JINR and CERN Directorate. The
sponsors and partners of the conference were companies IBS Platformix, Supermicro Computer,
NIAGARA, Jet Infosystems, Intel, RSC Group, Cisco, Dell EMC, ITCost.

       The organizers of the NEC symposium traditionally paid a particular attention to young scientists
and specialists. Within the scope of the symposium the IT-School "Big Data mining and distributed
systems" was organized. 32 students and young scientists from the leading universities of Russia attended
the School.

       Presentations of the delivered reports, the electronic version of the Book of Abstracts as well as
conference photos are available on the official site of the Conference at http://nec2019.jinr.ru.
