Multikernel

A multikernel operating system treats a multi-core machine as a network of independent cores, as if it were a distributed system. It does not assume shared memory but rather implements inter-process communications as message-passing.Baumann et al., [https://people.inf.ethz.ch/troscoe/pubs/sosp09-barrelfish.pdf "The Multikernel: a new OS architecture for scalable multicore systems"], to appear in 22nd Symposium on Operating Systems Principles (2009)The Barrelfish operating system, http://www.barrelfish.org/. Barrelfish was the first operating system to be described as a multikernel.
