Abstract
Introduction Currently PVM is the standard for developing parallel applications in workstation environments. One of its goals is to use the computational power of idling workstations. In practice many users refrain from opening their machine to other users' PVM processes. This is due to their experience that such a process, which usually requires a lot of resources (CPU and memory), increases the response time for short interactive commands, i.e. reduces his own productivity. In the following, we describe an approach which enhances existing queuing systems with a support for parallel PVM applications and allows the migration of PVM processes to other machines. Hence, users who start to work interactively on their machine are no longer bothered by resource consuming PVM processes. 2 Load Leveling with Queuing Systems The interaction of the user with the queuing system is based on the notion of jobs. Formally, a job is the obligation of the queuing
