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[3][4] with a "just enough operating system" (JeOS) approach.
[5] The operating system is primarily targeted towards virtualized environments for cloud computing, or HPCs due to its design as a lightweight kernel (LWK).
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.
[16] minIP,[17] a minimalist IP stack in ANSI C able to provide enough functionalities to serve a simple static webpage, is being developed as a proof of concept to learn the fundamentals in preparation for an x86-64 assembly re-write planned for the future.
