ABSTRACT:
Embodiments of the invention are generally related to retrieving debug data from a plurality of nodes of a parallel computer system. To retrieve debug data, a message may be broadcast from a service node of the system to each of the plurality of nodes via a first network, the message indicating a debug operation that is to be performed. A node of the plurality of nodes may transfer an interrupt signal to the rest of the plurality of nodes via a second network. Upon receiving the interrupt signal, the plurality of nodes may perform the debug operation comprising transferring the debug data to the service node via a third network.
