A parallel computer system comprising a plurality of processing elements and an input/output system interconnected by a communications network. The input/output system includes a plurality of input/output devices connected to the communications network for receiving messages from, and transmitting messages to, the processing elements over the communications network. The processing element during the storage operation generates a series of messages for transmission over the communications network to successive input/output devices. Each message includes a data item from one of a series of storage locations. The processing element generates for each stripe of a selected number of data items a check value for transmission in a message to another of the input/output devices. During a reconstruction operation, the processing element receives the data items and the check values from at least some of the input/output devices and performs a reconstruction operation in connection with each check value and a stripe of data values for which the check value was generated during the storage operation thereby to reconstruct data items stored in at least one other of the input/output devices.

Parallel computer system including parallel storage subsystem including

A computer comprising a plurality of processing elements and an input/output processor interconnected by a routing network. The routing network transfers messages between the processing elements and the input/output processor. The processing elements perform processing operations in connection with data received from the input/output processor in messages transferred over the routing network and transferring processed data to the input/output processor in messages over the routing network, the processing elements being connected as a first selected series of leaf nodes. The input/output processor includes a plurality of input/output buffers connected as a second selected series of leaf nodes of the routing network for generating messages for transfer over the routing network to a series of processing elements forming at least a selected subset of the processing elements during an input/output operation.
