چکیده

Even though real-time systems have the stringent constraint of completing tasks before their deadlines, many existing real-time operating systems do not implement fault tolerance capabilities. In this paper we summarize fault tolerant real-time scheduling policy for dynamic tasks with ready times and deadlines. Our focus in this paper is the implementation, which includes fault-tolerant scheduling, re-scheduling, and recovery mechanisms in the FT-RT-Mach operating system, a fault-tolerant version of RT-Mach. A realtime train control application is then implemented using the FT-RT-Mach operating system. Copyright  1999 John Wiley & Sons, Ltd.

Fault-Tolerant Real-Time Mach: A Timeline-based approach

Even though real-time systems have the stringent constraint of completing tasks before their deadlines, many existing real-time operating systems do not implement fault tolerance capabilities. In this paper we describe the development and implementation of a non-preemptive fault tolerant real-time policy for aperiodic dynamic tasks. We implemented non-preemptive fault-tolerant scheduling and re...

RT-IPC: An IPC Extension for Real-Time Mach

Interprocess communication (IPC) provides the fundamental mechanism for the Mach microkernel to be extensible and exible. Mach IPC provides eecient communication mechanisms for many applications. However, it does not provide suucient functionality for real-time applications which have rigid timing constraints among threads. In Real-Time Mach (RT-Mach), we have extended Mach IPC to be priority i...

RTCAST: lightweight multicast for real-time process groups

We propose a lightweight fault-tolerant multicast and membership service for real-time process groups which may exchange periodic and aperiodic messages. The service supports bounded-time message transport, atomicity, and order for multicasts within a group of communicating processes in the presence of processor crashes and communication failures. It guarantees agreement on membership among the...

An Approach to Constructing Modular Fault-Tolerant Protocols

Modularization is a well-known technique for simplifying complex software. Here, an approach to modularizing fault-tolerant protocols such as reliable multicast and membership is described. The approach is based on implementing a protocol’s individual properties as separate microprotocols, and then combining selected micro-protocols using an event-driven software framework; a system is construc...

MPI/FT: Architecture and Taxonomies for Fault-Tolerant, Message-Passing Middleware for Performance-Portable Parallel Computing

MPI has proven effective for parallel applications in situations with neither QoS nor fault handling. Emerging environments motivate fault -tolerant MPI middleware. Environments include space -based, wide -area/web/meta computing, and scalable clusters. MPI/FT , the system described here, trades off sufficient MPI fault coverage against acceptable parallel performance, based on mission requirem...
