In an information system which includes a local site including a cache file server coupled with a host computer, and a remote site including a remote file server coupled with a surrogate processing computer, a method determines whether each of one or more files of data for a data processing request is cached or not. If yes, the method executes data processing for each cached file to produce results in local site. If no, the method includes creating a file list of files to be processed in remote site; sending the file list and processing program to the surrogate computer; if the processing is sufficiently effective to be done by the surrogate computer, receiving results of the processing executed in remote site, and, if not, then receiving an unprocessed file list from remote site and executing data processing in local site and receiving any results already executed in remote site.
