Looks like my TinyKVM project, except it runs specialized programs instead of regular ELFs? TinyKVM also runs functions, with a fast execution timeout. I proved that without I/O you can essentially run KVM programs with native performance, and sometimes more due to automatic hugepages. I measured LLMs to run at 99.7% native speed using eg. Mistral 7B. For example, the STREAM memory benchmark doesn't use hugepages by default, and so the terminal version runs slower than the TinyKVM version due to hugepage-tables, but of course runs at the same speed once you modify the benchmark to use the same advantage. However, it does require modifying the program.<p>See: <a href="https://ieeexplore.ieee.org/document/10475832" rel="nofollow">https://ieeexplore.ieee.org/document/10475832</a><p>I also implemented VM resets using page-table rewrites and CoW memory sharing, so that no memory is shared across different requests. This can be implemented as tail-latency in a cache.<p>I ended up adding support for most languages. All the systems languages, Go, v8, LuaJit etc. Go was by far the most annoying to support as it uses signals.
