Best practices with HDF5 and Datasets - Mathematica Stack Exchange

WebBasically, your best case disk-read speed and your worst case disk read speed for a given slice of your dataset will be fairly close with a chunked HDF dataset (assuming you chose a reasonable chunk size or let a library choose one for you). With a simple binary array, the best-case is faster, but the worst-case is much worse. WebNumerical Data. Huge numerical datasets are routine for the Wolfram Language. Its powerful array primitives make large-scale array manipulation both easy to specify and highly efficient. And its integrated collection of state-of-the-art algorithms makes a broad range of sophisticated data analysis immediately accessible.
