Abstract
A computer system having a CPU which executes instructions and uses resources of the computer system as the instructions are being executed. A monitoring device of the computer system monitors the quantity of resources used by the execution device and outputs a signal indicating that a limiting threshold of the use of the computer system resources has been approached, reached, or exceeded. Once the system resource limiting threshold has been reached, the executing process in the CPU is interrupted and data associated with the executing program is saved in a first save area. If a user of the computer system does not take any action after a predetermined period of time, the saved data associated with the executing program is moved to a second save area which has a slower access time than the first save area. After another predetermined period of time has elapsed without input from the user indicating a resume of the previously executing program, the saved data is further moved to a different storage area having a slower access time than the second storage area. The saved data is used to restart the execution of the instructions which have been interrupted, upon the input of a restart command from a user, so that the computer does not have to re-execute the previously executed instructions.
