Fault Tolerant Matrix Operations for Networks of Workstations Using Multiple

Recently, an algorithm-based approach using diskless checkpointing has been developed to provide fault tolerance for high-performance matrix operations. With this approach, since fault tolerance is incorporated into the matrix operations, the matrix operations become resilient to any single processor failure or change with low overhead. In this paper, we present a technique called multiple checkpointing to enable the matrix operations to tolerate a certain set of multiple processor failures by adding the capacity for multiple checkpointing processors. The results on a network of workstations have shown that this technique improves not only the reliability of the computation but also the performance of checkpointing. 1

Strategic Types and Peformances of Small Firms in Korea

This study attempts to identify the patterns of strategic behaviour of small firms in Korea in conjunction with their performance. Based on the data from 79 small firms across four industries, the results reveal that there appear to be four common strategic attributes cost efficiency, innovative differentiation, marketing differentiation, and asset parsimony and five strategic types of firms which have distinct combinations of these strategic attributes innovative, versatile, marginal, and reactive types. Each type of firm was also found to have different organisational characteristics and performance level. Finally, this study discusses the comparative management issue in the field of strategic management and offers some practical implications for managers of small firms.ope
