1. A computing system comprising: a system management node; a plurality of computing nodes, each computing node having a BIOS (Basic Input/Output System) and at least one processor chip having an error register and a processor; a management controller at each computing node; at least one buffer at each computing node, wherein the management controller of a respective computing node that includes the at least one buffer is configured to extract error data from the at least one buffer without accessing through the at least one processor chip of the respective computing node; wherein the BIOS of each computing node is configured to instruct the processor of the at least one processor chip to read error data from its error register and write the error data into the at least one buffer of the respective computing node; and wherein the system management node is configured to receive the error data from each of the management controllers.
