This requirement cannot be satisfied by an external file server. Once solution is to employ an internal parallel I/O subsystem, in which I/O nodes with DASD are linked wo the same interconnection network that connects the compute nodes. The option of increasing the number of I/O nodes together with the number of compute nodes allows for a balanced architecture. Indeed, most multicomputer vendors provide internal parallel I/O subsystems as part of their product offerings. However, these systems typically attempt to preserve a Unix-compatible interface, hiding or abstracting the parallelism. New interfaces may be required to fully utilize the capabilities of Parallel I/O.}, comment = {A very nice survey of multiprocessor file systems issues. Published version of feitelson:pario-tr.} }
