....calculation which will be able to take over. This solution requires the nodes in the graph to be deterministic, and for the messages to be delivered to both of the nodes in the same order. The former problem is application specific, and the latter problem has been addressed in a number of systems [BC91, vRHB94] Unfortunately, this approach leads to a factor of two slowdown over the non replicated implementation. A second approach to handling processing node failures is to duplicate the inputs to nodes. If the data is saved on a separate node, then it can be re played at a new node started to ....

....master brings the issue of robustness, and it also causes traffic concentration. For a group where members are sparsely populated in the network, the heartbeat may not be able to synchronize all participants. Therefore, MTP does not scale well to large group size and network size. 2. 5 ISIS ISIS [13] [14] provides two set of protocols, CBCAST and ABCAST, to achieve causal data ordering and total causal data ordering, respectively. It relies on the underlying reliable multicast mechanism to guarantee data 8 delivery. The causal data order in ABCAST is determined by a virtual time comparison. ....

....River solves the additional problem of ensuring that these applications perform robustly even when underlying hardware and software components perform erratically. Although previous work has addressed how to design large scale systems that can tolerate correctness faults in individual components [7, 17, 32, 34], little work has focused on how to design systems that tolerate performance faults, where a performance fault is the unexpected low performance of a component within the system. Within clusters, performance faults are commonplace [2] especially for modern disks. Some of the reasons static and ....

We are using a predecessor of CORBA, ISIS C , developed partly in house in association with the ISIS project [Birman Cooper 1991].

....with only the main goals of the specific application (the service) the programmer must also take care of all the aspects related to the replication. It would be very useful to have tools to help in the handling of such aspects. Such tools do exist. It is, for example, the case of the ISIS system [BJS87, BC91]. ISIS is a distributed toolkit that provides a group abstraction and a set of reliable broadcast protocols that makes the handling of replicates an easy job. Failure detection and membership management are handled in a coherent way with message delivery. However, the current version of this ....

....CSP [Hen90] does distinguish transmitter from receiver. It has multiway synchronisation, and indeed a notion of broadcasting, but a strange one where speakers can synchronise but listeners cannot. Programming. Examples are hard to find. Even literature that describes broadcast as a primitive [BC91] gives no examples of use. It is perhaps relevant that the computation model of CBS can be classified as multiple instruction single data stream , a class usually regarded as empty. It turns out however, that some of the examples in this paper are re inventions, reported earlier in [HT92, YLC90, ....

....environments, not only must such systems perform correctly, but they must also operate with high performance. Much of the previous work in distributed computing has addressed the design of large scale systems that function correctly, in spite of correctness faults of individual components [18, 49, 82, 86]. However, there has been little development of techniques to tolerate performance faults unexpected performance fluctuations from the components that comprise the system. Due to this shortcoming, many systems are overly sensitive to performance variations, in that global performance is high if ....

Fortunately, much of the previous work in the field of distributed computing has addressed the design of large scale systems that can tolerate such correctness faults in individual components [18, 24, 49, 61, 82, 86, 107, 114]. The practical notion behind such work is that distributed and parallel systems consist of both hardware and software components that will periodically fail; a system that works continuously on top of such unreliable components must be designed to operate in spite of such failures. A good example ....

....is the time since file f was last used, and n(f) is the number of times file f was used. The first term therefore captures the relative age of the executable in comparison with other files, while the second captures its importance. Both terms are in the range [0, 1] so the score is in the range [0, 2]. The executables with the highest score is evicted, until the desired disk space is cleared. Thus jobs that were run repeatedly are allowed to stay longer, out of anticipation that they will be used again. 6 Conclusions Our first conclusion is that building communication systems is hard, and ....

A cooperation space of a group includes all tools provided by OSACA to exchange messages between group members. Point to point message sending, broadcast, totally ordered broadcast (as in ISIS [Birman 90] are some of them. In the basic form, a broadcast consists in sending a message to all the group members. Nevertheless, one can easily find lots of applications which often need some kind of communication primitives that allow a group member to send a message to a restricted set of other ....

We mention PVM [13] HeNCE [1] Isis [2], MPI [4] and EcliPSe [10] as example of such software systems. At the present time, heterogeneous workstation clusters are not ideal replacements for supercomputers, mainly because of their low interconnection bandwidth and reliability.
