HACC super big dataset single-precision (float32) number of data points/values: 1621417608 The complete dataset consists of 500 time steps, with each time step containing approximately one trillion particles and occupying about 31 TB. For each particle, the dataset includes multiple variables, such as x, y, z, vx, vy, and vz. Dataset #27035 here contains only the spatial coordinates (x, y, z) in a particular region and represents just 1/768 of the data from time step 499. The SDRBENCH-EXASKY-HACC-data-sbig-size.tar.gz contains only one small region of the full dataset (timestep:499) at that scale.
