CLOCK SYNCHRONIZATION METHOD OF DISTRIBUTED MULTIPLE PROCESSING SYSTEM WITH LOOSELY COUPLED STRUCTURE

摘要

establishing a system clock control block 21 in a system clock operating processor; performing an environment construction for clock synchronization by the first operating the system clock control block 21 in the processor to establish a local clock control block 22 in SMP 7 originated in FEP 2, 3 and BEP 4, 5 as a transaction processor; driving a local clock control block 22; generating a system standard clock in a system clock control block to re-control a local clock in order to accord the system standard clock by operating the local clock control block 22 in the processor as a standard clock to receive a change- finished message from the local clock control block 22 in all processors to output it into a clock synchronization result output device.
