Abstract :
A description is given of the MARUTI operating system, which is designed to support real-time applications on a variety of hardware systems. The kernel supports objects as primitive entities and provides a communication mechanism that allows transparent distribution in networked systems. Fault tolerance is provided through replication and consistency-control mechanisms. MARUTI supports guaranteed-service scheduling, in which jobs that are accepted by the system are verified to satisfy general time constraints. These time constraints include those that govern interrupt processing, which allows the MARUTI approach to succeed where more rigorous approaches do not. The result is that MARUTI applications can be executed in a predictable, deterministic fashion
