Abstract

WebCom is a metacomputer based on the Condensed Graphs model of computing. Within this model, applications are represented as directed acyclic graphs with the nodes representing tasks and arcs their sequencing constraints. This paper presents the job management system used in WebCom. We describe the techniques required to apply common job management concepts, such as suspension, migration and monitoring, to the execution of applications expressed as Condensed Graphs.
