| Summary: | distributed resource management in multicomputer systems used for database and multimedia applications. We first study the design issues to support distributed processor management in a failure-prone multicomputer system. We develop a distributed processor management framework based on a distributed information structure, a reliable processor coordination mechanism, and fault-tolerant processor allocation and deallocation procedures. Based on this framework, resource management processes will not be blocked by faulty nodes or links and only fault-free processors are allocated to tasks. In addition to possessing a fault-tolerant design, our scheme can also achieve comparable or better performance than existing centralized schemes. We then propose the dual-mode communication architecture to enhance the performance of interconnection networks for database applications. We develop a new virtual channel management technique to meet the performance requirements of both short and long messages. Our work highlights the effect of message length on network performance and addresses the necessity of using different channel allocation mechanisms for messages of different lengths. Our study shows that with the same amount of additional hardware support, the dual-mode scheme is superior over existing routing approaches, when message lengths vary in a wide range. |
