- We are using A/ROSE the Apple/Realtime Operating System Environment in our
- macintosh laboratory at the institute for computer design and fault tolerance.
- In our configuration A/ROSE runs on Serial NB MCP cards plugged in nubus slots
- on macintosh computers. These cards are connected with Apple V24/RS232 cables and
- form a distributed system.
- We also use MPW as a development environment.platform. In order to run
- the programs under A/ROSE you have to link some spezial libraries.
- When we run a distributed application on the cards we use the Macs as
- I/O devices to monitor and control the programflow. Our main interests are
- to examine fault-tolerant mechanisms and fault-tolerant protocols.
- Therefore we have developed a communication kernel which provides communication
- promitives and a fault injection tool to trigger particular fault situations.
- Until now we have implemented and tested several fault-tolerant protocols
- on this system.
- Our expierence with A/ROSE is the following:
- - the programs have to be implemented in C or assembler
- - there is no support for floating point operations
- A/ROSE together with the Serial NB Card satisfies our application requirements
- and we are going to use it in more areas.
