Computer architecture and method of operation for multi-computer distributed processing with finalization of objects

摘要

The present invention discloses a modified computer architecture (50, 71, 72) which enables an applications program (50) to be run simultaneously on a plurality of computers (M1, . . . Mn). Shared memory at each computer is updated with amendments and/or overwrites so that all memory read requests are satisfied locally. During initial program loading (75), or similar, instructions which result in memory being re-written or manipulated are identified (92). Additional instructions are inserted (103) to cause the equivalent memory locations at all computers to be updated. In particular, the finalization of JAVA language classes and objects is disclosed (162, 163) so finalization only occurs when the last class or object present on all machines is no longer required.
