Thread control system and method in a computer system

摘要

The executing threads in CPU 100~103 are checked at random intervals in a specified range by interrupt execution modules 109~112, the results of the checks are stored in executing thread memory areas 113~116 and values of counters 117~120 that are corresponding to the executing threads are incremented. If the values of the counters 117~120 exceed specified values, applicable threads are judged to be operating abnormally and priorities of the applicable threads are lowered so as to prevent the abnormal operations of the threads.
