Cactus Parameters Request : HTTPD

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.

pause	no	Pause ? (no)
refresh_seconds	-1	Page refresh time seconds (-1)
single_step	no	Do one step then pause ? (no)
steering_frequency	1	How many iterations between steering events (1)
terminate	no	Kill the simulation ? (no)
timeout_seconds	0	Polling timeout seconds (0)
timeout_useconds	0	Polling timeout micro-seconds (0)
until_expression	iteration+40 < time*100	Pause if this expression evaluates to true. (iteration+40 < time*100)
until_expression_active	no	Use until_expression parameter ? (no)
until_it	0	Pause at this iteration (0)
until_it_active	no	Use until_it parameter ? (no)
until_time	0	Pause after this simulation time (0)
until_time_active	no	Use until_time parameter ? (no)
verbose	no	Print information about HTTP requests (no)

Fixed Parameters

hunt	yes	Should the server hunt for a port if the specified one is taken ? (yes)
port	5555	HTTP port number to use (can be overridden by shell variable HTTPD_PORT) (5555)
provide_pages	yes	Should the server provide any pages ? (yes)
queue_length	4	Listen queue length (4)
use_pthreads	yes	Use a threaded implementation if possible ? (yes)
