Multikernel

Last updated

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. [1] [2] Barrelfish was the first operating system to be described as a multikernel.

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

A computing platform, digital platform, or software platform is an environment in which software is executed. It may be the hardware or the operating system (OS), a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed using the services provided by the platform. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run.

Amoeba is a distributed operating system developed by Andrew S. Tanenbaum and others at the Vrije Universiteit Amsterdam. The aim of the Amoeba project was to build a timesharing system that makes an entire network of computers appear to the user as a single machine. Development at the Vrije Universiteit was stopped: the source code of the latest version (5.3) was last modified on 30 July 1996.

<span class="mw-page-title-main">Barrelfish (operating system)</span>

Barrelfish is an experimental computer operating system built by ETH Zurich with the assistance of Microsoft Research in Cambridge. It is an experimental operating system designed from the ground up for scalability for computers built with multi-core processors with the goal of reducing the compounding decrease in benefit as more CPUs are used in a computer by putting low-level hardware information in a database, thus removing the need for driver software.

The version history of the HarmonyOS distributed operating system began with the public release of the HarmonyOS 1.0 for Honor Vision smart TVs on August 9, 2019. The first expanded commercial version of the Embedded, IoT AI, Edge computing based operating system, HarmonyOS 2.0, was released on June 2, 2021 for phones, tablets, smartwatches, smart speakers, routers, and internet of things. Beforehand, DevEco Studio, the HarmonyOS app development IDE, was released in September 2020 together with the HarmonyOS 2.0 Beta. HarmonyOS is developed by Huawei. New major releases are announced at the Huawei Developers Conference (HDC) in the fourth quarter of each year together with the first public beta version of the operating system's next major version. The next major stable version is then released in the third to fourth quarter of the following year.
