The Muen Separation Kernel is the world's first Open Source microkernel that has been formally proven to contain no runtime errors at the source code level. It is developed in Switzerland by the Institute for Internet Technologies and Applications (ITA) at the University of Applied Sciences Rapperswil (HSR). Muen was designed specifically to meet the challenging requirements of high-assurance systems on the Intel x86/64 platform. To ensure Muen is suitable for highly critical systems and advanced national security platforms, HSR closely cooperates with the high-security specialist secunet Security Networks AG in Germany.

The webpage contains instructions for building the kernel yourself, for installing it in a virtual machine, and for running it on real hardware.

In order for Microkernel's to work well, lots of stuff has to be built in hardware that is not needed in a Monolithic kernel.

Partition states or context switching and message passing could be done in hardware for example to make Microkernel's much more efficient.

That IS, if researchers could ever agree on exactly how a Microkernel should work and which parts should have hardware built for them. THEN Intel and AMD or ARM etc could do a cost analysis and determine if a market exists for them.
(HINT: One doesn't exist. :-) )

So why hasn't a Microkernel evolved to the state of LINUX?

One problem is that researchers cannot even agree on a final design plan for a Microkernel. I would also like to point out that this research has been a technological cul-de-sac since the 80's.

For the sake of the argument, and to save all of those PhD's from irrelevance, :-) say Microkernel design was finished and a plan was presented to Intel, AMD and ARM engineers for large scale deployment of such hardware.

The PLAN would require large portions of silicon to be added to todays machines which do not have what I would call excessive NANNY STATE kernel's running on them. (i.e. MONOLITHIC kernels).

Microkernels (and the ideas around them) would STILL run slower than MONOLITHIC kernels, consume more power to run per watt than a Monolithic kernel requires of computer hardware.

In short, we would have a collapse of the computer industry, everyone would go broke, and we would have to build thousands of new Nuclear power plants to make it all work.

Finally, they would all melt down and well, that would be that.



PS: For the PhD's sending me hate mail (undoubtedly using a Monolithic Kernel to send it), please remember I do not control your department funding, I do not write your NSF grant papers and I am sure your research will turn out something...

One of these days. (Wink Wink Wink).
