METHOD FOR IMPROVING SYSTEM AVAILABILITY AFTER THE FAILURE OF PROCESSORS IN A PROCESSOR PLATFORM

摘要

When tasks are processed in a processor platform, the processing procedure is distributed over a logical chain of several processors of said processor platform. When one of the processors fails, the data is lost and the entire chain is left blocked for a considerable period. According to the inventive method, this problem is solved by forming another chain in which significant status-related data is transferred to the following processor. When restarted, the processor which failed can then reload said data and resume the status that it had before the failure.
