Utility Programs provided by IOHDF5

Thorn IOHDF5 provides the following utility programs:

• hdf5_recombiner
  Recombines chunked HDF5 datafile(s) into a single unchunked HDF5 datafile. By applying the -single_precision command line option, double precision floating-point datasets can be converted into single precision during the recombination.
• hdf5_convert_from_ieeeio
  Converts a datafile created by thorn IOFlexIO into an HDF5 datafile. Your thornlist must include this thorn in its thornlist in order to build the FlexIO-to-HDF5 utility program.
• hdf5_convert_from_sdf
  Converts a datafile created by thorn CactusIO/IOSDF or other Cactus-external programs into an HDF5 datafile. Your thornlist must include this thorn in its thornlist in order to build the SDF-to-HDF5 utility program.

All utility programs are located in the src/util/ subdirectory of thorn IOHDF5. To build the utilities just do a

  make <configuration>-utils

in the Cactus toplevel directory. The executables will then be placed in the exe/<configuration>/ subdirectory.

All utility programs are self-explaining - just call them without arguments to get a short usage info. If any of these utility programs is called without arguments it will print a usage message.
