Appeal No. 96-3124
Application 08/265,585
fault handler 204 shown in Figure 4, residing in each of
computers 10a through 10n shown in Figure 1, performs five
fault detection checks. We note that none of the five fault
detection checks is directed to specifically detect only a
power failure. We note that one of these five fault detection
checks, number 4, which determines if the task execution was
executed within a predeter-mined time would detect a computer
that has had a power failure. However, the check would not
know if the task was not executed timely because of a power
failure or because of another failure such as a software
error. Thus, Whiteside fails to detect a power failure as
well as fails to produce a power-failure signal.
Whiteside teaches in column 10, lines 47-56, that once
one
of the five fault detection checks determines an error, the
fault
handler 204 transmits an error message to the other computers,
and the other computers store the error message when received,
each computer decides if the computer identified by the error
