It is not possible to pass the thorn or implementation name of a thorn that merely declares the parameter as used. + +While setting a new parameter value is immediately reflected in +Cactus' database, the value of the parameter is not changed +immediately in the routine that sets the new value: It is updated only +the next time a routine is entered (or rather, when the +\code{DECLARE\_CCTK\_PARAMETERS} is encountered the next time). It is +therefore advisable to set the new parameter value in a routine +scheduled at a time earlier to when the new value is required. \end{Discussion} \begin{SeeAlsoSection} |
