Abstract: Systems and methods may provide for inserting one or more preemption instructions while compiling a computer program. The one or more preemption instructions being inserted within a preemption window in the computer program reduces the number of live registers at each preemption instruction position. Further, the preemption instruction instructs which registers are to be saved at a particular program position, typically the registers that are live at that program position. The compiled program may be run in an execution unit. A preemption request may be made to the execution unit and executed at a next available preemption instruction in the program being run in the execution unit.
