processor writes to the common storage area and all the
processors see an identical value in some portion of the data
set concurrently.” (Examiner’s Answer at 6.)
We cannot find that Kametani and Papadopoulos teach or
would have suggested the “wherein" clauses of claim 4. The
claim recites in pertinent part the following limitations:
wherein, to synchronize changes in the state of
operation of the processors and/or to handle
processor jobs in a synchronous manner, a data set
is able to be entered into said common storage area
of each of said plurality of memories by the
processor that first reaches a predetermined
synchronization point during execution of a process;
wherein said interrupt controllers detect a
change in said data set, said controllers providing
interrupt signals that are fed to said processors,
through which means, according to an identifier in
the entry in the common storage area, a change in
the state of operation of said processors and/or a
synchronous job processing is able to be initiated
....
In short, the claim specifies that when one of a plurality of
processors enters data into a common storage area, interrupt
