Abstract:
1. A method of retrieving debug data from a plurality of nodes of a parallel computer system, each node comprising at least one processor and memory, the plurality of nodes comprising at least one first node, a plurality of second nodes coupled with the first node, and a third node, comprising: broadcasting a message from a service node of the computer system to the plurality of nodes via a first network connecting the service node to the plurality of nodes, wherein the message indicates a debug operation to be performed by the plurality of nodes; generating an interrupt signal at the third node; transferring the interrupt signal from the third node to remaining nodes of the plurality of nodes via a second network coupling each node of the plurality of nodes to at least one other node; and at each of the second nodes, in response to receiving the interrupt signal, performing the debug operation comprising transferring debug data from the second node to the respective first node.
