摘要：the fault tolerance for real-time application avoidable by help of the protocol is CRR. However, existing checkpoint implementation support only non-real-time applications as the checkpoint overhead is usually non deterministic. In this paper, we represent an implementation of checkpoint scheme with the RTAI 3.8 supported by Linux, where services provided by the RTOS makes the checkpoint overhead, including the time to place recover the system from a failure is predictable. It also gives an optional view of the hard real-time definition and an appropriate perspective on why low cost general purpose computer can be an effective operating system available. The RTAI 3.8 for Linux describe here is a viable and effective open-free source software approach for adding hard real time capabilities to a widely available general purpose operating system. It keeps real time applications separated from non real time ones, achieving high efficiencies for both kinds of executions by affording appropriate synchronization and communication tools to allow an efficient interaction between two environments.
