Preemptable remote execution facilities for the V-system

摘要: A remote execution facility allows a user of workstation-based distributed system to offload programs onto idle workstations, thereby providing the with access computational resources beyond that provided by his personal workstation. In this paper, we describe design and performance in V system, as well several implementation issues interest. particular, focus on network transparency environment, preemption migration remotely executed programs, avoidance residual dependencies original host. We argue preemptable workstations be used "pool processors" without interfering use their owners significant overhead for normal programs. general, conclude cost is modest compared similar amount computation service dedicated "computation engines".
