Computer architecture and method of operation for multi-computer distributed processing and coordinated memory and asset handling
First Claim
1. A method of running simultaneously on a plurality of computers at least one application program each written to operate on only a single computer but modified by a modification routine to run simultaneously on the plurality of computers, said computers being interconnected by means of a communications network, said method comprising the steps of:
- (i) executing different portions of said application program(s) on different ones of said computers and for each said portion creating a like plurality of substantially identical objects each in the corresponding computer.

Abstract
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 addition, the initialization of JAVA language classes and objects is disclosed (162, 163) so all memory locations for all computers are initialized in the same manner. The finalization of JAVA language classes and objects is also disclosed (162, 163) so finalization only occurs when the last class or object present on all machines is no longer required. During initial program loading (75), or similar, instructions which result in the application program (50) acquiring (or releasing) a lock on a particular asset (50A, 50X-50Y) (synchronization) are identified. Additional instructions are inserted (162, 163) to result in a modified synchronization routine with which all computers are updated.
