we present an approach to design of fault tolerant computing systems. in this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. code combining techniques are very effective, which one of these codes are turbo codes. the algorithm-based fault tolerance techniques that to detect errors rely on the c...

We present a peer logging system for reducing performance overhead in fault-tolerant distributed shared memory systems. Our system provides fault-tolerant shared memory using individual checkpointing and rollback. Peer logging logs DSM modification messages to remote nodes instead of to local disks. We present results for implementations of our fault-tolerant technique using simulations of both...

Fault-tolerant consensus has been studied extensively in the literature, because it is one of the most important distributed primitives and has wide applications in practice. This paper surveys important results on fault-tolerant consensus in message-passing networks, and the focus is on results from the past decade. Particularly, we categorize the results into two groups: new problem formulati...

The use of metalevel architectures for the implementation of fault-tolerant systems is today very appealing. Nevertheless, all such fault-tolerant systems have used a general-purpose metaobject protocol (MOP) or are based on restricted reflective features of some object-oriented language. According to our past experience, we define in this paper a suitable metaobject protocol, called FT-MOP for...

some applications are critical and must designed Fault Tolerant System. Usually Voting Algorithm is one of the principle elements of a Fault Tolerant System. Two kinds of voting algorithm are used in most applications, they are majority voting algorithm and weighted average algorithm these algorithms have some problems. Majority confronts with the problem of threshold limits and voter of weight...
