Abstract: An apparatus for handling a failed processor of a multiprocessor system including at least two processors interconnected by processor interconnects for facilitating transactions of the processors. The at least two processors include a first processor set as a default boot processor in response to a boot up operation of the multiprocessor computer, and a second processor. The apparatus includes: a baseboard management module for detecting and receiving health information of the processors; a multiplexer coupled to the baseboard management module and respectively to the processors, the multiplexer being operative to switch between the processors; and a processor ID controller coupled to the baseboard management module and respectively to the processors. In response to the health information indicating the first processor has failed, the processor ID controller sets the second processor as the default boot processor and the baseboard management module enables the multiplexer to switch to the second processor.

Abstract: A method for handling a failed processor of a multiprocessor system, the multiprocessor system comprising at least two processors interconnected by processor interconnects for transactions between processors, the processors comprising a first processor and a second processor, the first processor being set as a default boot processor in response to a boot-up operation of the multiprocessor system. The method comprises: detecting and receiving, via a baseboard management module, health information of the at least two processors; providing a multiplexer operative to switch between the at least two processors, the multiplexer being coupled to the baseboard management module and respectively to the at least two processors; and, in response to the health information indicating the first processor has failed, setting, via a processor ID controller, the second processor as the default boot processor and enabling, via the baseboard management module, the multiplexer to switch to the second processor.
