Abstract

Techniques and mechanisms for capturing an image of processor state at one node of multiple nodes of a multi-processor platform, where the processor state includes some version of data which the node retrieved from another node of the platform. In an embodiment, a disruption of power is detected when a processor of a first node has a cached version of data which was retrieved from a second node. In response to detection of the disruption, the data is saved to a system memory of the first node as part of an image of the processor's state. The image further comprises address information, corresponding to the data, which indicates a memory location at the second node. In another embodiment, processor state is restored during a boot-up of the node, wherein the state includes the captured version of data which was previously retrieved from the second node.
