Check/Modify Parameters
Thorn IOUtil
Parameters in Cactus can be either fixed or steerable. Steerable parameters are those which can be modified during a simulation. To change steerable parameters, edit the values and press the submit button. Before applying the new parameter value, Cactus will check that the parameter lies in the allowed range. Note that there is currently no log of parameters which have been modified.
The tables below show the parameter name, current value and description. The default value of each parameter is shown in brackets at the end of the description.
Steerable Parameters
The following parameters are steerable, but you do not have authorisation to change them. To change parameters you must first register on the Simulation Control Page.
| checkpoint_every | -1 | How often to checkpoint (-1) |
| checkpoint_file | checkpoint.chkpt | File name for regular checkpoint (checkpoint.chkpt) |
| checkpoint_ID_file | checkpoint.chkpt | File name for initial data checkpoint (checkpoint.chkpt) |
| checkpoint_keep | 1 | How many checkpoint files to keep (1) |
| checkpoint_on_terminate | no | Checkpoint after last iteration (no) |
| out_downsample_x | 2 | Factor by which to downsample output in x direction. Point (0,0,0) is always included. (1) |
| out_downsample_y | 2 | Factor by which to downsample output in y direction. Point (0,0,0) is always included. (1) |
| out_downsample_z | 2 | Factor by which to downsample output in z direction. Point (0,0,0) is always included. (1) |
| out_dt | -2 | How often to do output by default (-2) |
| out_every | -1 | How often to do output by default (-1) |
| out_single_precision | no | Output data in single precision ? (no) |
| parfile_update_every | 0 | How often to update the parameter file for steered parameters (0) |
| recover_file | checkpoint.chkpt | Basename of recovery file (checkpoint.chkpt) |
| verbose | standard | Level of screen output for I/O (standard) |

| filereader_ID_vars | all | List of variables to read in from the given initial data files (all) |
| new_filename_scheme | yes | Use the new filename scheme for output files ? (yes) |
