IOHDF5 Parameters

Parameters to control the IOHDF5 I/O method are:

• IOHDF5::out_every (steerable)
  How often to do periodic IOHDF5 output. If this parameter is set in the parameter file, it will override the setting of the shared IO::out_every parameter. The output frequency can also be set for individual variables using the out_every option in an option string appended to the IOHDF5::out_vars parameter.
• IOHDF5::out_vars (steerable)
  The list of variables to output using the IOHDF5 I/O method. The variables must be given by their fully qualified variable or group name. The special keyword all requests IOHDF5 output for all variables. Multiple names must be separated by whitespaces.
  An option string can be appended in curly braces to a group/variable name. Supported options are out_every (to set the output frequency for individual variables) and hyperslab options (see section J2.5 for details).
• IOHDF5::out_dir
  The directory in which to place the IOHDF5 output files. If the directory doesn't exist at startup it will be created.
  If this parameter is set to an empty string IOHDF5 output will go to the standard output directory as specified in IO::out_dir.
