External timer interrupts are used to signal the saving and restoring o the status of a unit of work during the operation of a data processing system which may have plural central processors. This allows one processor to be executing more than one unit of work concurrently. When an interrupt occurs, the status of the current unit of work which is executing on the processor is saved in the control blocks which represent the unit of work. The interrupt is then serviced, and a unit of work is dispatched. The dispatched unit of work may or may not be the one which was executing at the time of the interrupt.
