Design, analysis, and simulation of I/O architectures for hypercube multiprocessors

Several issues concerning the design of an I/O (input/output) system for a multiprocessor such as a hypercube are examined. A methodology is proposed for connecting the I/O processors to such a system for efficient I/O access. The effect of I/O communication on the multiprocessor network is analyzed. Different disk organizations that can be employed within such a system are evaluated to see which organization has a better performance. It is observed that parallelism in serving an I/O request plays a dominant role in the scientific workload. The problem of mapping specific data structures such as matrices onto the disks so that the data can be accessed efficiently is considered
