This means + that a lot of the operating system code is maintained outside of GNU Mach, + and while this code may go through a complete redesign, the code of the + microkernel can remain comparatively stable. + + * **it's scalable** + + Mach is particularly well suited for SMP and network cluster techniques. + Thread support is provided at the kernel level, and the kernel itself takes + advantage of that. Network transparency at the [[IPC]] level makes + resources of the system available across machine boundaries (with NORMA + IPC, currently not available in GNU Mach). + + * **it exists** + + The Mach microkernel is real software that works Right Now. It is not a + research or a proposal. You don't have to wait at all before you can start + using and developing it.
