Abstract

When a computing system operates with multipleinstruction multiple-data (MIMD) streams, the overall system reliability is defined as the probability that at least, one path exists between each pair of the system nodes.

In this paper the reliability models of MIMD systems are classified as

  • 1.

    (1) a combinatorial model;

  • 2.

    (2) a state transition model;

  • 3.

    (3) a link enumeration model; and

  • 4.

    (4) a spanning-tree model.

These models are analyzed in such a unified manner that seven network configurations are considered. These configurations are star, tree, ring, dual-bus hypercube, normal hypercube, multiple global buses, and near-neighbor mesh. Hence, the corresponding structured Algol-like algorithms are given. The reliability evaluation of every interconnection is presented, taking into account the configuration size. Moreover, a comparison of models and configurations is emphasized to help in ranking them for MIMD operational conditions.
