Distributed operating systems

QNX ( or ) is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market.

ChorusOS is a microkernel real-time operating system designed as a message passing computing model. ChorusOS began as the Chorus distributed real-time operating system research project at the French Institute for Research in Computer Science and Automation (INRIA) in 1979. During the 1980s, Chorus was one of two earliest microkernels (the other being Mach) and was developed commercially by startup company Chorus Systèmes SA. Over time, development effort shifted away from distribution aspects to real-time for embedded systems.

MOSIX is a proprietary distributed operating system. Although early versions were based on older UNIX systems, since 1999 it focuses on Linux clusters and grids. In a MOSIX cluster/grid there is no need to modify or to link applications with any library, to copy files or login to remote nodes, or even to assign processes to different nodes – it is all done automatically, like in an SMP.
