Is there any particular problem you are trying to solve with this, or is =

I've had this paper sitting on my desk for a couple of years, but I =

still haven't been able to find the time to read it, "Designing and =

Implementing Lightweight Kernels for Capability Computing" , buy Rolf =

Riesen et. al.:

http://onlinelibrary.wiley.com/doi/10.1002/cpe.1361/pdf

It lists a variety of kernels designed for this purpose, so you might =

want to take a look at it, and see if you can get the source code to any =

of them.

Also, what's wrong with Linux? Would a stripped down Linux kernel be =

suitable. One of the early selling points of Linux was it's modular =

design that allowed you to remove components to increase the performance =

and reduce resource requirements. Have you looked at just paring down =

the Linux kernel as much as possible?  This is something I've always =

wanted to do but never had the time.
