Abstract: Embodiments include apparatuses, methods, and systems of routing network containing a set of sources, a primary destination, a set of secondary destinations, and one or more routing elements. A routing element includes an input port, a set of output ports including a primary output port and a set of secondary output ports, and a control unit. The control unit is arranged to select a secondary output port to deliver a received message when the intended destination of the message is a secondary destination and the secondary output port is in a functional state. Otherwise, the control unit is arranged to select the primary output port to deliver the received message to the primary destination when the intended destination is the secondary destination and the secondary output port that reaches the secondary destination is in a nonfunctional state. Other embodiments may also be described and claimed.

Abstract: Techniques of debugging a computing system are described herein. The techniques may include generating debug data at agents in the computing system. The techniques may include recording the debug data at a storage element, wherein the storage element is disposed in a non-core portion of the circuit interconnect accessible to the agents.
