method for improving system availability in the event of a prozessorplattform processors

摘要

The processing of tasks in a processor platform is carried out by distributing the processing procedure over a logical chain of a number of processors in the processor platform. If one of the processors fails, the data is lost and the whole chain remains blocked for a relatively long time. The invention provides a remedy for this by forming a further chain in which significant data relating to state is transferred to the subsequent processor. When restarted, the failed processor can then load this data again and thereby assume a state as before the failure.
