| 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.
