Process Migration in the Sprite Operating System
This paper describes a process migration facility for the Sprite operating system. In order to provide location-transparent remote execution, Sprite associates with each process a distinguished home node, which provides kernel services to the process throughout the process's lifetime. System calls that depend on the location of a process are forwarded to the process's home node. Performance mea...
متن کاملIssues in Process Migration
Process migration means moving a process in the middle of its execution from one processor or host to another, for a variety of reasons. Usually, processes are migrated with the aim of balancing the work load across the cluster so that the capacity of underutilized nodes are also exploited. The idea of process migration is borne out of the fact that in the over whelming cases of non migratory s...
متن کاملTransparent Process Migration for Personal Workstations*
The Sprite operating system allows executing processes to be moved between hosts at any time. We use this process migration mechanism to offload work onto idle machines, and also to evict migrated processes when idle workstations are reclaimed by their owners. Sprite's migration mechanism provides a high degree of transparency both for migrated processes and for users. Idle machines are identif...

متن کاملExperience with Process Migration in Sprite
This paper reports on experience with the Sprite process migration facility. Sprite provides transparent remote execution to support load sharing through the use of idle workstations. Process migration is used to reclaim workstations when their owners return. On Sun 3/75 workstations, the cost of selecting an idle host and invoking a remote process is about 400 milliseconds. This time is substa...
