Bringing together Mobile Agents and Data Analysis in PSEs

We explore an approach based on remote evaluation, rather than the traditional TCP/IP based remote procedure calls for parallelism on a network of workstations. The remote evaluation approach is embodied in mobile code -- referred to as a mobile agent. We investigate issues in employing mobile agents in problem solving environments (PSEs), with the Aglets workbench from IBM Research. A PSE is generally composed of various computational resources that need to interoperate efficiently. We propose a mechanism whereby mobile code can be used to migrate the computation, enabling complex communication and distribution patterns, and support interoperability between various distributed resources. An application based on a neural network is used to show the concepts involved. 1 Introduction Advances in networking technology and computational infrastructure have made it possible to build large meta-computing environments, that support distributed components for large scale, high per..
