Multi-partition computer system, failure handling method and program therefor

A failure handling method for a multi-partitioned computer system in which a plurality of nodes are logically divided into a plurality of partitions, comprising:

• a node contained in one of said partitions performing steps of:
• upon receiving a packet, comparing the partition identification information uniquely assigned to its own partition against the partition identification information contained in the receive packet;
• and
• if these pieces of information do not match each other, judging and discarding said receive packet as an incorrect packet,
• wherein a crossbar which connects between said nodes performs the processes of:
• detecting an error in a packet received;
• extracting said partition identification information in the receive packet for which the error has been detected;
• and
• notifying the error to the partition having said partition identification information extracted.

A non-transitory computer readable medium storing a failure handling program executed on said node and a crossbar which connects between said nodes in a multi-partitioned computer system in which a plurality of nodes are logically divided into a plurality of partitions, wherein said failure handling program causes a node contained in one of said partitions, upon receiving a packet, to execute a processing of comparing the partition identification information uniquely assigned to its own partition against the partition identification information contained in the receive packet, and if these pieces of information do not match each other, judging and discarding said receive packet as an incorrect packet,

• wherein said failure handling program causes said crossbar to execute a processing of:
• detecting an error in a packet received;
• extracting said partition identification information in the receive packet for which the error has been detected;
• and
• notifying the error to the partition having said partition identification information extracted.
