I am describing architecture for computing. Units work together in a group. More units can be added as needed. More units in a group mean that the group can handle more data.
I want to write something like this:
If the group is overloaded, a new unit can be added to take over a part of a job.
However, I'm not sure about the phrase "to take over a part of a job". Is it correct in this context? Or would you express it differently?
