BareMetal
BareMetal is an exokernel-based single address space operating system (OS) created by Return Infinity.
It is written in assembly to achieve high-performance computing with minimal footprint with a "just enough operating system" (JeOS) approach. The operating system is primarily targeted towards virtualized environments for cloud computing, or HPCs due to its design as a lightweight kernel (LWK). It could be used as a unikernel.
It was inspired by another OS written in assembly, MikeOS, and it is a recent example of an operating system that is not written in C or C++, nor based on Unix-like kernels.

Multitasking on BareMetal is unusual for modern operating systems. BareMetal uses an internal work queue that all CPU cores poll. A task added to the work queue will be processed by any available CPU core in the system and will execute until completion, which results in no context switch overhead.
An API is documented but, in line with its philosophy, the OS does not enforce entry points for system calls (e.g.: no call gates or other safety mechanisms).
BareMetal OS has a build script to pull the latest code, make the needed changes, and then compile C code using the Newlib C standard library.
