System for assigning boot strap processor in symmetric multiprocessor computer with watchdog reassignment |
摘要 |
A boot strap assignment system is disclosed for a symmetric multiprocessor computer in which the role of the boot strap processor is assigned to one of the working processors by a central agent as part of power-on configuration. The system includes a system management processor which monitors the operation of the multiprocessor computer and controls a switching circuit that selectively transmits the boot strap assignment signal from the central agent to the working processors. Since the management processor monitors environmental conditions and shut-down events, it can predict the failure of working processors and assign the bootstrapping function appropriately. A watch dog timer is also provided in case the bootstrapping fails so that another working processor can be assigned the task of booting up the computer.
