PURPOSE:To provide a close coupling multiprocessor with high reliability by performing processor relief and instruction retrying processing based on a loading circumstance and an error frequency circumstance of a system when an error for which retrying instruction is possible occurs. CONSTITUTION:Following control is performed, that is the retrying of instruction retrying is applied to a logical unit in which the error occurs only when it is decided that both no high loading state and no error occur frequently by monitoring circuits 111, 211 when a retrial enabling error occurs and the processor relief is performed in the other case than the above-mentioned in the close coupling multiprocessor system having both the monitoring circuits 111, 211 which monitor the loading circumstance and error generating circumstance of the logical units (CPU) 100, 200 and a processor relief function. |
