摘要
In a computer system for parallelly executing a plurality of tasks by sharing a plurality of resources in a data base of a computer, a use sequence of the resources to be used by each task is inputted to the computer prior to the execution of the tasks. A possibility of deadlock due to sharing of common resources amojng the tasks is checked based on the information on the use sequence, and a deadlock avoidance information table is prepared. When the task issues a start request, the deadlock avoidance information table is referred and the start of the task which has the possibility of the deadlock is delayed.
