Abstract

A resource management system can effectively shorten the runtime of batch jobs in a network of workstations (NOW). This is achieved with load balancing mechanisms to distribute the load equally among the hosts. To avoid conflicts between interactive users and batch jobs, a resource management system must be able to migrate batch jobs from an interactive host to an idle host. Common resource management systems offer process migration only for sequential jobs but not for parallel jobs. Within the SEMPA project a resource management system with batch queuing functionalities including checkpointing and migration is designed and implemented. We focus on PVM applications because PVM offers dynamic task management and an interface to resource management systems 1 . 1 Introduction Parallel scientific computing applications, e.g. in computational fluid dynamics, require a large amount of CPU time and memory. Therefore, they are often run on massively parallel systems. However, networks of wo...
