“…We made our measurements on a collection of about 40 10-MIPS workstations all running the Sprite operating system [9,12]. Four of the workstations served as file servers, and the rest were diskless clients.…”

We analyzed the user-level file access patterns and caching behavior of the Sprite distributed file system. The first part of our analysis repeated a study done in 1985 of the BSD UNIX file system. We found that file throughput has increased by a factor of 20 to an average of 8 Kbytes per second per active user over 10-minute intervals, and that the use of process migration for load sharing increased burst rates by another factor of six. Also, many more very large (multi-megabyte) files are in use today than in 1985. The second part of our analysis measured the behavior of Sprite's main-memory file caches. Client-level caches average about 7 Mbytes in size (about one-quarter to onethird of main memory) and filter out about 50% of the traffic between clients and servers. 35% of the remaining server traffic is caused by paging, even on workstations with large memories. We found that client cache consistency is needed to prevent stale data errors, but that it is not invoked often enough to degrade overall system performance.

“…Early landmark systems, such as V [9], Sprite [35], Accent [39], and LOCUS [37], implemented native operating system facilities for migrating processes between nodes on a tightly coupled cluster. Glunix [14] provides facilities for managing applications on a tightly connected networks of workstations.…”

In this paper, we describe the design and implementation of a distributed operating system for ad hoc networks. Our system simplifies the programming of ad hoc networks and extends total system lifetime by making the entire network appear as a single virtual machine. It automatically and transparently partitions applications into components and dynamically finds them a placement on nodes within the network to reduce energy consumption and to increase system longevity. This paper describes our programming model, outlines the design and implementation of our system and examines the energy efficiency of our approach through extensive simulations as well as validation of a deployment on a physical testbed. We evaluate practical, power-aware, general-purpose algorithms for component placement and migration, and demonstrate that they can significantly increase system longevity by effectively distributing energy consumption and avoiding hotspots.

“…These aspects include enviroimental variables, and resources allocated or read from the operating system. These problems have been studied at length elewhere [3,11]. Moreover, these problems are not specific to thread migration systems, but apply to any distributed environment, including PVM, MPI, and any DSM.…”
