Semi-User-Level Communication Architecture

چکیده
This paper introduces semi-user-level communication architecture, a new high-performance light-weighted communication architecture for inter-node communication of clusters. Different from traditional kernel-level networking architecture and user-level communication architecture, semi-user-level communication architecture removes OS kernel from its message-receiving path while reserves an OS trapping on its message-sending path. No interrupt handling is needed. This new communication architecture doesn’t support user-level access to network interface. It provides good portability, security, and support for heterogeneous networking environment and usage of large memory. Semi-user-level communication architecture has been implemented on a SMP workstation cluster system called DAWNING-3000, which is interconnected through Myrinet. Communication performance results are given and overhead distribution is analyzed.

متن کاملAn Agent Model in a Multiagent System Architecture for Automating Distributed Systems
In this paper we discuss the conceptual foundation for a Multi-Agent System (MAS) which is being prototyped automate mission operations for unmanned scientific satellites. A basic agent model has been developed and is used to characterize the agents of the MAS. Using this model three classes of agents have been currently identified and incorporated into the MAS prototype. These are: the user in...
