Abstract

The present invention provides a new multi nodal computer system comprising a number of nodes on which chips of different types reside. The new multi nodal computer system is characterized in that there is one clock chip per node, each clock chip controlling only the chips residing on that node said chips being appropriate for sending a check stop request to the associated clock chip in case of a malfunction. A new check stop handling method is characterized in that depending on the source of the check stop request the clock chip that received the check stop request initiates a system check stop, a node check up, or a chip check stop.
