Standard Parameters

Here we describe a few of the standard parameters used by IOUtil to control output.

• IO::out_dir
  The name of the directory to be used for output. All the I/O methods described here will write by default to this directory (which itself defaults to the current working directory). Individual methods have parameters which can direct their output to a different directory.

• IO::out_criterion
  The criterion that decides when to output. The default is to output every so many iterations (see IO::out_every).

• IO::out_every
  How often, in terms of iterations, each of the Cactus I/O methods will write output. Again, individual methods can set their own parameters to override this. The default is to never write output.

• IO::out_dt
  How often, in terms of simulation time, each of the Cactus I/O methods will write output. Again, individual methods can set their own parameters to override this. The default is to never write output.
