Utility programs provided by IOFlexIO

Thorn IOFlexIO provides the following utility programs:

• ieee_recombiner
  Recombines chunked IEEEIO datafile(s) into a single unchunked IEEEIO datafile.
• ieee_merge
  Merges the contents of its input files into a single output file.
  This might be useful for IOFlexIO datafile created by different runs.
• ieee_extract
  Extracts a hyperslab from all datasets of the input file.
  You can select a hyperslab by specifying an origin and an extent (eg. 128x128x128+32+32+32 selects a 128-cubed hyperslab with origin (32, 32, 32)).
• ieee_convert_from_cactus3
  Converts Cactus 3 IEEEIO datafiles into Cactus 4.
  It also takes a textfile as input with mapping information for variable names.
• ioinfo
  Displays the contents of an IEEEIO datafile (number of datasets stored, datatype, rank, dimenions, and number of attributes for each dataset).

All utility programs are located in the src/util/ subdirectory of thorn IOFlexIO. 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.
