Should say basically do not have what similarities, the starting point is different, or high performance computing, parallel computing, is in order to break through the single resource limitation, let more machines to complete a task together, and the cloud, is usually through virtualization technology, let the excess resources of a single physical machine independent, isolation for multiple tasks, their starting point is different, even opposite, but cloud computing now category is very wide also, so there will be some areas of overlap, such as cloud cluster server can again, and then a little like the parallel computing, but the cloud server cluster in general are used to provide network services, rather than computing services,
