|Redundancy
|Multiple redundancy and backup at components and devices level; device-as-a-whole level redundancy is optionaland seldom used|Redundancy at components and devices level; device-as-a-whole level redundancy is optionaland sometimes used|Data and power redundancy could be achieved by practices and external devices like RAID, ECC RAM, UPS etc., otherwise no. Device-as-a-whole level redundancy is always usedif better reliability needed
|Redundancy relying on large amounts of nodes, each node itself is not redundant; Software has to be programmed in a way to handle tasking reordering and data consistency in case of node failing
|Not a priority; nodes aren't redundant and software seldom considers node failing as tasks are usually parallel to make use of peak performance
|Least concerned; programs are usually specifically built for specific supercomputer; sometimes supercomputers are even built for a specific task (e.g. Anton series)
