I assume Dumsani refers to simfactory. How do you change the parameter 
file that simfactory tells Cactus to use for a restart? I admit that in 
that case I usually go in and change the file in the output directory 
(simulations/name/...), but there must be a better way. I didn't have to 
do that so often, so I never bothers to find out myself.

Does simfactory actually observe a --parfile option on submission of a 
restart? It probably will not complain if you try, but does it actually 
do what you want?
