8 Schedule

This section lists all the variables which are assigned storage by thorn CactusWave/IDScalarWaveCXX. Storage can either last for the duration of the run (Always means that if this thorn is activated storage will be assigned, Conditional means that if this thorn is activated storage will be assigned for the duration of the run if some condition is met), or can be turned on for the duration of a schedule function.
