Abstract :
A modular distributed operating system, ROSE, that provides support for building reliable applications is presented. In the kernel layer, network IPC and failure detection capabilities are provided. Above the kernel layer, replicated address space (RAS) objects are provided whose content is accessible with a high probability despite hardware failures. In the layer above, a resilient process (RP) abstraction which allows user processes to survive hardware failures with minimal interruption is provided. Two different implementations of RP are given: one checkpoints the information about its state in a RAS object periodically; the other uses replicated execution by executing the same code in different nodes at the same time
