Abstract: A method for discovery of a cluster of objects in an arbitrary undirected graph. A subset of the objects is determined by performing a random walk starting from a first object of the objects and following a plurality of random edges of subsequent objects, the subset comprising the first object and the subsequent objects. An enlarged subset is determined by enlarging the subset to include other objects well-connected to the subset. It is determined whether the enlarged subset is a cluster.

Abstract: Various approaches are described for auditing integrity of stored data. In one approach, a data set is provided from a client to a storage provider, and the data set is stored at a first storage arrangement by the storage provider. An auditor determines whether the data set stored at the first storage arrangement is corrupt without reliance on any part of the data set and any derivative of any part of the data set stored by the client. While the auditor is determining whether the data set stored at the first storage arrangement is corrupt, the auditor is prevented from being exposed to information specified by the data set. The auditor outputs data indicative of data corruption in response to determining that the data set stored at the first storage arrangement is corrupt.

Abstract: Various embodiments of the present invention are directed to photonic interconnects that can be used for on-chip as well as off-chip communications between computer system components.
