DSLab Summer School 2011 – Utilizing GNU/Linux for safety related systems

Lanzhou, Gansu, ChinaAugst 15-202011

Linux was not designed for safety related systems, so why use it?

* Security is becoming an issue in safety related systems (it actually always was but we simply ignored it…)

* Processor capabilities are growing rapidly mandating a rethinking of the federated nature of may safety related systems

* The paradigm of keeping systems un-modified for 10-20years is crumbling technical demands mandate a higher level of flexibility while retaining safety related properties

Using FLOSS, notably GNU/Linux, is not the answer to all of these issues, but it is worth considering, and in cases where it fits it can be a very attractive solution, both technically and economically.
