I like to use the term fault propagation a
lot. It has so many uses. When we talk about multiprocessor systems,
we think about fault propagation across a bus or other interconnect at
the electrical level, the protocol level and even at the service
level. It is bad enough if a fault in a piece of code manages to take
down the processor it runs on. It is multiplicatively worse if the
fault propagates to take down other processors directly or indirectly.
