Huawei spent 10 years developing Hongmeng operating system to compete with mainstream Western operating systems. Its smoothness is beyond imagination.

According to news on January 19, the Hongmeng system, which has been honed for 10 years, is finally going to set sail. Why do I say this? Because behind this is Huawei’s absolute self-research support.

The new Hongmeng that debuted yesterday has ended the 30-year history of the terminal operating system kernel being dominated by the West, and is more flexible, safer, and smoother than it.

"Compared with the mainstream operating systems in the West, the Hongmeng base layout has been improved to achieve full-stack self-development." Huawei said proudly.

In Huawei’s view, they insist on long-term investment in software root technology research and take root down to the root. After ten years, they finally changed the history that the software root technology of the operating system was dominated by Europe and the United States.

From the operating system kernel, file system, to programming language, compiler/runtime, programming framework, to design system, integrated development environment, as well as AI framework and large model, etc., full-stack automatic Research, this is Hongmeng’s confidence.

Of course, Hongmeng kernel has built a new concurrency model to overcome the "fake" concurrency problem of "one person working while everyone watches" in multi-core situations; a new concurrency model is designed, which is lighter than threads and better than concurrency. Processes are easier to schedule and task switching overhead is reduced by 50%.

Memory management adopts innovative hybrid dynamic large page technology, which allocates 4K, 16K or 64K large pages according to scenarios. The memory management efficiency is increased by more than 3 times, and the fluency is greatly improved. The above scheduling mechanism, memory allocation model, etc., allow The system continues to run smoothly.
