....for both tasks and files. The gradient descent paradigm is used to make on line load balancing decisions for tasks, and balancing is based on redistribution of files so as to maintain 4 an equal file load at all nodes. Other work on dynamic task assignment using process migration includes [Ba91, Be89, Es90, Jo90, So87, Ba91, Ba85, Ku91, So87, Xu92] . 3 Framework for the Two Problems of Task Assignment and Transaction Clustering The task assignment problem addresses the clustering of a set of tasks on a set of processors so as to optimize system performance. Therefore we first describe the formal environment within which this problem is ....

....the Sprite operating system [10] does not provide this level of indirection it uses an rpc based communication system so a transparency violating home node is necessary to deal with location dependent calls. However, no systems offer complete freedom from residual dependencies. Joosen et al. [15] argue that only Charlotte [2] and the V System [25, 26] can be said to offer transparent process migration, though even these systems impose certain restrictions on programmers. They also maintain that to get useful benefits from migration it should be restricted to systems with little or no ....

....processor organization, configuration of communication switch, etc. This paper only addresses the design issues of process migration in loosely coupled systems. Process migration has been a useful and a desirable feature in distributed systems. Smith [14] Jul et al. 15] and Joosen and Verbaeten [16] summarize the benefits of process migration facilities as follows: Reconfiguration long running processes will not face problems of system shutdown or system failures; in such cases these processes could be migrated to other available machines. Load balancing moving processes across the ....
