Appeal No. 1997-4120 Page 2
Application No. 08/347,341
BACKGROUND
The invention at issue in this appeal relates to
synchronizing processors. In systems having multiple
processors that process related tasks and exchange data with
each other, processing must be synchronized. The invention
synchronizes changes in the state of operation of the
processors and ensures that the processors execute jobs
synchronously. According to the invention, the first
processor to reach a synchronization point while executing a
process enters a data set into a common storage area.
Interrupt controllers associated with the processors detect
the entry and send interrupt signals to the processors to
initiate a synchronous job or to change the processors’ state
of operation.
