differences. + +Once somebody has added a new machine to the database it is very easy for +everybody else to use that machine. + +It uses the concept of a master source tree, that gets copied to the +supercomputer using rsync. + +Single commands will then configure and build Cactus, submit simulations, +check the status of simulations, stop simulations and delete simulations. + +Simfactory guards
