5 Jan 2018 Brussels - The European Commission site runs a news item "OSIRIS: unravelling the mysteries of plasmas in astrophysics and in the laboratory" and the need of running this plasma code on HPC systems. OSIRIS is a fully relativistic, electromagnetic particle-in-cell (EM-PIC) framework. Researchers have performed some of the largest numerical plasma simulations in supercomputers worldwide.
OSIRIS is being used in more than 30 institutions by more than 150 researchers worldwide. Written in Fortran 2003 and C, its code is massively parallel, with demonstrated parallel scalability up to 1,6 million cores and sustained petascale performance in production runs, the news item says.
