Abstract
Abstract The present invention finds application in the field of multi-computers, and more particularly to the collection of data from nodes in a multi-computer system. The multi-computer includes a number of nodes for performing computing and data transfer functions, each node communicating with one or more other nodes in the multi-computer through a message routing network. Each node includes a measurement device for measuring predetermined events occurring within each node. The system includes a concentrator bus for communicating measurement data packets produced by the measurement device, and a concentrator node for outputting a multiplexed serial sequence of the measurement data packets in response to a parallel asynchronous input of the measurement data packets received over the concentrator bus from the nodes. The multiplexed serial sequence of measurement data packets is communicated over a collection bus to a collection node that demultiplexes and processes the measurement data packets.
