The HelenOS project is an effort to develop a
working operating system. HelenOS supports SMP,
multitasking, and multithreading on 32-bit and
64-bit, little-endian and big-endian processor
architectures, among which are AMD64/EM64T
(x86-64), ARM, IA-32, IA-64 (Itanium), 32-bit MIPS,
32-bit PowerPC, SPARC V9, and Xen. The extent to which
these architectures are supported differs from
architecture to architecture. Some run on real
hardware, and some run only in a simulator.
