:speeds up XDS by chopping the DATA_RANGE into (2-99) pieces, and feeding each piece to a new process. That process may run on the local machine, or a different one (but this needs to be configured). Unless specifically set up for a given computer environment (e.g., at a synchrotron site), usually don't set ''both'' MAXIMUM_NUMBER_OF_PROCESSORS ''and'' MAXIMUM_NUMBER_OF_JOBS to values >1 !

Some amount of "overcommiting of resources" is OK, i.e. if you are the sole user of a Dual-core workstation, you may set both parameters to 2. Wolfgang Kabsch found that this utilizes the machine even a bit better than either MAXIMUM_NUMBER_OF_PROCESSORS=2 or MAXIMUM_NUMBER_OF_JOBS=2.
