ABSTRACT:
A cpu-set type multiprocessor system allows a cpu of a cpu-set that has a hardware exception to disable itself and notify the system. The system assigns processes of the cpu-set that include the problem cpu to another cpu-set. The disabling of the problem cpu and transfer of the related processes to another cpu-set allows the system to failsoft so that other cpu-sets the multiprocessor system can continue to run and a recovery of the processes being run on the problem cpu-set occurs.
