DATASET NAME: NYX
DATASET OWNER’S NAME AND CONTACT: Sheng Di or Zarija, sdi1@anl.gov
ARRAY DIMENSION: 3D
Dimension sizes: 512x512x512
DATA NATURE (INTEGER or DECIMAL,…): CECIMAL
PHYSICAL DESCRIPTION OF THE DATASET:
compressible cosmological hydrodynamics simulation code (Nyx): https://ccse.lbl.gov/Research/NYX/
The Nyx simulation data are post-analysis data composed of 3D arrays in space (such as dark matter density and temperature).

Some datasets such as the dark matter density of NYX are better to be transformed to log-scale because they have very large value ranges while a large majority of data are fairly small (close to 1 or 0).
So, we put two versions of the datasets in the benchmark (original data and log-scale data).
