Abstract
A network of computer node interface to globally addressable memory system that provides persistent storage of data exchange periodic connectivity information. The exchanged connectivity information provides information regarding node failure to other nodes in the system, and the surviving nodes use the information to determine which node, if any, has ceased functioning. Various processes are used to recover the portion of the global address space for which the failed node was responsible, including RAM directory, disk directory, or file system information. Additionally, nodes may be subdivided into groups and connectivity information is exchanged between nodes belonging to a group. Each group then exchanges group-wise connectivity information and failures may be recovered.
