MULTIPROCESSOR SYSTEM, TASK SCHEDULING METHOD AND TASK SCHEDULING PROGRAM

摘要

PPROBLEM TO BE SOLVED: To avert a system down due to a closed state of a processor during execution of an unrecoverable code. PSOLUTION: An operating system reads processor failure information 50 when it is determined that a task contains an unrecoverable code 54 based on attribute information contained in a task header 100. The operating system determines, when the occurrence of correctable failure in a processor (own processor) to which the task is assigned is discovered, whether the correctable failure is caused in all processors including the own processor or not. When a processor without the occurrence of the correctable failure is present, the operating system performs replacement processing of a task execution-scheduled queue. The operating system instructs the processor without the occurrence of the correctable failure (or the processor to which the task including the unrecoverable code 54 is newly assigned) to execute the task.
