✦ Synopsis

This paper presents optimization models for a fault tolerant software by selecting a set of versions for a given program. The objective is to maximize the reliability of the software satisfying a budget limitation. Optimization models are developed for two block recovery schemes: (1) independent recovery block and (2) consensus recovery block. The paper also presents simple formulas to calculate the reliability of the two schemes.

It is important to design computer systems to tolerate some failures. This paper proposes two-level recovery schemes, soft checkpoint (SC) and hard checkpoint (HC), which are useful to recover from failures. Soft checkpoint is less reliable and less overhead than those of HC, and is set up between H

Clusters and distributed systems offer two important advantages, viz. fault tolerance and high performance through load sharing. When all computers are up and running, we would like the load to be evenly distributed among the computers. When one or more computers break down the load on these compute
