Appeal No. 1997-0760
Application No. 08/003,000
DECISION ON APPEAL
This is a decision on appeal from the examiner's final
rejection of claims 20 through 23, 29, and 30, which are all
of the claims pending in this application.
Appellants' invention relates to an integrated software
architecture that efficiently executes programs on a highly
parallel multiprocessor system. More specifically, the
architecture includes a multithreaded operating system which
provides two levels of scheduling. Claim 20 is illustrative
of the claimed invention, and it reads as follows:
20. An integrated operating system program for controlling
execution of a plurality of multithreaded computer programs in
a multiprocessor system having a plurality of tightly-coupled
processors that share a common memory and a common atomic
resource allocation mechanism, the plurality of multithreaded
computer programs comprising one or more executable processes,
the integrated operating system program comprising:
multithreading scheduling means to be executed
simultaneously on one or more of the processors for
distributively scheduling execution of executable processes;
and
user-side scheduling means to be compiled with the
executable processes, the user-side scheduling means and
executable processes comprising an executable computer program
for scheduling the execution of other executable processes and
for examining one or more work request queues stored in the
