How do clustered systems differ from the multiprocessor systems ?
Answers
Answer: Clustered systems are typically constructed by combining multiple
computers into a single system to perform a computational task distributed
across the cluster. Multiprocessor systems on the other hand could be a single
physical entity comprising of multiple CPUs. A clustered system is less tightly
coupled than a multiprocessor system.
Clustered systems communicate using messages, while processors in a
multiprocessor system could communicate using shared memory. In order for
twomachines to provide a highly available service, the state on the two
machines should be replicated and should be consistently updated. When one
f the machines fail, the other could then take‐over the functionality of the
failed machine.
