Re: [seL4] high-availability system should have these software services

It would be particularly neat to do a fault-tolerant implementation of the seL4 API and a refinement proof that it implemented the spec when the number of concurrent failures was limited. On Jun 12, 2015 4:40 AM, "Gernot Heiser" wrote:

In general, a high-availability system should have the following software services I want to develop a high-availability system on seL4, can anyone give me some suggestions?

Does that have to all be in the OS? To what degree could it be a library independed of OS?

What is the “OS” becomes a bit relative with a true microkernel (which QNX isn’t). But you’re right if you think this should certainly not be part of the *kernel*.
