PURPOSE:To improve the reliability of a fault processing function for a composite computer system using plural computers, by providing a deciding function for collation, diagnosis and majority to each computer. CONSTITUTION:A computer system link (CSL)6 is provided with a device number register 7 which stores the device numbers of CSLs of other computers, an address register 9 which has a communication with an instruction register 5 via a memory bus 2 for a physical address, a data register 10 which stores the data to be exchanged with other computers, and a coincidence detecting part 8 which detects the coincidence between the value of the register 7 and that of the register 9. The CSL6 is connected to a CSL of another computer via an interface bus 11. An instruction OP of the register 5 can access freely to the local memory of another computer by a physical address PA and via the CSL6. |
