During the year 2017, the CRESCO high performance computing clusters have provided more than 30millions hours of “core” computing time, at a high availability rate, to more than one hundred users, supporting ENEA research and development activities in many relevant scientific and technological domains. In the framework of joint programs with ENEA researchers and technologists, computational services have been provided also to academic and industrial communities.

This report, the ninth of a series started in 2008, is a collection of papers illustrating the main results obtained during 2017 using the CRESCO/ENEAGRID HPC facilities. The significant number of contributions proves the importance of the HPC facilities in ENEA for the research community. The topics cover various fields of research, such as materials science, efficient combustion, climate research, nuclear technology, plasma physics, biotechnology, aerospace, complex systems physics, renewable energies, environmental issues, HPC technology. The report shows the wide spectrum of applications of high performance computing, which has become an all-round enabling technology for science and engineering.
