Abstract: A method, service and search system for network resource address repair are provided. The method which may be provided as a service over a network, includes: receiving a network resource address that is incorrect; dividing the network resource address into a host address and a path within the host address; searching for the host address, and repairing the host address if an error is found; and, if the host address if found or repaired, searching for the path. A search system is provided which includes a means for activating a network resource address repair if a network resource address is incorrect; and a means for repairing a network resource address. The means for repairing a network resource address includes inputting the host address or the path separately into the query processing means of the search engine.

Abstract: A method and system for use by a cache-less component contained in a group of two or more components each having access to shared data stored in a shared segment of memory connected to the components, at least one of which is cache-less. Synchronization of the components in the group is assured by detecting memory accesses performed by components in the group. Upon detecting that any one of the components accesses data in the shared segment of memory, a state associated with the data is set to a first value.
