A distributed real-time operating system
1992 / IEEE
This item was taken from the IEEE Periodical ' A distributed real-time operating system ' Two versions of the HARTS operating system, which is based on Software Components Group's pSOS uniprocessor kernel, are presented. In one version, pSOS services are enhanced to provide interprocessor communication and a distributed naming service. In the second version, real-time fault-tolerant communication, including reliable broadcasting, clock synchronization, and group communication are added to the HARTS operating system. Three tools to evaluate the performance and fault tolerance dependability of HARTS hardware and software-a synthetic-workload generator, a monitor, and a fault injector-are described. The generator produces a synthetic workload, the monitor collects the performance data, and the fault injector simulates faulty behavior for further study. Together these tools create a facility that lets the user perform a wide range of experiments. The tools are independent, so they are equally effective separately or together, depending on the requirements.<
