OSNews, Generic OSes BareMetal is an open source 64-bit OS for x86-64 based computers. It is written in Assembly, and applications can be written in Assembly or C/C++. It's aimed at three target segments (High Performance Computing, Embedded Applications, and Education). It's also designed to be simple, and it's really small. Under 16Kb small. Version 0.4.8 was released recently, which includes updates to the C application library, updated documentation, and better support for SMP. It's good to see some innovation in the startup/hobbyist OS space. We wish them well!

RE[3]: Why x86 assembly?

Multi-threading is supported but not in the way that other Operating Systems use it.

BareMetal OS uses a Process Queue. An application can throw as many "work loads" as it wants into the Process Queue and any available CPU Cores will begin to work on them.
