DATASET NAME: QMCPACK DATASET OWNER’S NAME AND CONTACT: Dingwen Tao (dingwen.tao@anl.gov) ARRAY DIMENSION (1D, 2D,…): 4D Dimension sizes: original data: 115x69x69x288 preconditioned data: 288x115x69x69 DATA NATURE (INTEGER, DECIMAL,…): DECIMAL ROW AND COLUMN NAMES: PHYSICAL DESCRIPTION OF THE DATASET (DIMENSION 1: TIME, DIMENSION 2: SPACE X, DIMENSION 3: SPACE Y, DIMENSION 4: TEMPERATURE, …: DIMENSION 1: x, DIMENSION 2: y, DIMENSION 3: z, DIMENSION 4: orbital index ENDIAN FORMAT (LITTLE, BIG): LITTLE PRECISION (DOUBLE, SINGLE): SINGLE ADDITIONAL GRAPHS: Further description: The original raw data are 115x69x69x288 in dimensions. However, according to the users, the data would become smoother in space after preconditioning, so they suggest to compress preconditioned data instead of original data. They are the same dataset, and the only difference is the different orders of the data in space.
