Possibilities for Active Messaging in PVM
Philip J. Mucci, Jack J. Dongarra · 1995
Active messaging is a communications model designed around the interaction of a network interface and its driving software in an operating system. By utilizing this model, the user can design applications that make better use of the available computing and communication resources. Currently, successful implementations exist only for a certain subset of workstations and network adapters. This paper is an exploration into a portable implementation of active messaging for possible inclusion to the PVM suite, a generalized framework for distributed computing. 1 Introduction Active messaging was first introduced at the University of California at Berkeley as a means to reduce the communication latency inherent in distributed computing. The idea was driven by the discrepancy in performance between traditional multiphase communication protocols and the actual access time of the network device. The concept of AM is as elegant as it is simple. When an AM arrives, the address of a user-defined...
