Architecture to transform data during transfer
HDF5 release 1.8 has a new feature that allows arithmetic operations (add/subtract/multiply/divide) to be performed on individual data elements as they are being written to/read from a file. A need has been expressed for transforms to perform operations on data aggregates, such as data reduction operations, node reordering on unstructured grids, or structured-to-unstructured grid conversions. An architecture is described in the accompanying talk that describes how this comprehensive approach might work.
