Abstract
A method, apparatus, and program for systematically testing the functionality of all connections in a multi-tiered bus system that connects a large number of processors. Each bus controller is instructed to send a test version of a snoop request to all of the other processors and to wait for the replies. If a connection is bad, the port associated with that connection will time out. Detection of a time-out will cause the initialization process to be halted until the problem can be isolated and resolved.
