A system and method to implement a resilient compute center. Parity bits are selected by a procedure using data derived by optimization using simulation of a single-channel system. The scaleable functional units have been optimized to execute mathematically intensive operations. Duplicate documents are included and excluded from the new set of documents based on a query independent metric for each such document. Extensive notes are provided for difficult phrases and words not normally found in a dictionary. A data string is selected from the at least one data string received, and technicaldiagnostic information related to the selected data string is retrieved.
