Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for cooperative fault tolerance and load balancing. In one aspect, a method includes receiving a request from an entity wherein the request includes metadata specifying a plurality of non-responsive servers to which the entity sent the request but that could not process the request; determining that the data processing apparatus is not a current home server for the entity based on information cached in the data processing apparatus, wherein the current home server is a server within a plurality of preferred servers that processes requests for the entity and, in response thereto: assigning the data processing apparatus as the current home server so that the entity will send subsequent requests to the data processing apparatus for processing; and sending a response to the entity.

Abstract: A system for identifying and sorting integrated circuit devices based on an encrypted Fuse ID information such as manufacturing and test information stored in the integrated circuit device, includes a test fixture for receiving an integrated circuit device to be identified and sorted. The system further includes a portable, user friendly processor communicatively coupled to the test fixture to read the stored encrypted device identification data from the integrated circuit device and decrypt the read encrypted Fuse ID information, and to compare the decrypted device identification data to a previously entered sort criteria and to identify and sort the integrated circuit device based on the outcome of the comparison.
