Transparent Process Migration: Design Alternatives and the Sprite Implementation

The paper describes the process migration mechanism used in the Sprite operating system to offload work onto idle machines, and also to evict migrated processes when idle workstations are reclaimed by their owners. The authors have made trade-off between four factors while designing and implementing the mechanism: transparency, residual dependencies, performance and complexity. The authors clai...

Transparent Process Migration: Design Alternatives and the Sprite Implementation

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...

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...

Experience 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...
