Presentation: "Message Passing Concurrency in Erlang. An architectural basis for scalable fault-tolerant systems"
Time: Friday 09:10 - 10:10
Location: Fleming Room
This talk is about the relationship between message passing concurrencyand software architectures for building scalable fault-tolerant systems.
Erlang was explicitly designed for building scalable fault-tolerantsoft real-time distributed systems. These systems are designed for non-stopoperation and have been in operation for over 15 years.
Anybody who designs such a system will soon realise that they need todo things like changing code in the running system without stoppingthe system or they will need to add power to the system by adding afew extra machines without stopping the service that the systemoffers.
Just about all the things you need to build such a reliablescalable system are built into Erlang from the start. These mechanismsin turn rely upon a underlying pure message-passing non-shared memory architectural view of the world. In addition Erlang provides a number of orthogonal error detection and correction mechanisms which provided a base for building fault-tolerant applications.
