This application is to provide necessary storage for all co-investigators in the large-size SNIC allocation, project SNIC 2023/1-48 "Large Scale Simulations in Biomolecular and Material Science". The project deals with large-scale molecular dynamics simulations of molecular systems consisting of the order of 10^5 atoms on the multiple-microsecond time scale, requiring to keep the atomistic trajectories, and ab-initio molecular dynamics simulations which require to keep electron density distributions for representative snapshots of the simulated system. Both types of tasks require extensive disk space of the order of terabytes which is outside the default user quota.
