A remote execution facility allows a user of a workstation-
based distributed system to offload programs onto idle
workstations, thereby providing the user with access to
computational resources beyond that provided by his personal
workstation. In this paper, we describe the design and
performance of the remote execution facility in the V
distributed system, as well as several implementation issues of
interest. In particular, we focus on network transparency of
the execution environment, preemption and migration of
remotely executed programs, and avoidance of residual
dependencies on the original host. We argue that
preemptable remote execution allows idle workstations to be
used as a "pool of processors" without interfering with use by
