Guy Harris (talk | contribs) Is this truly a multikernel system, with each CPU core running a kernel instance that communicates with the instances on other cores by message-passing, or is it just a system with some cores running one kernel and other cores running a different kernel, or is it both (e.g., with cores running kernel A communicating with cores running kernel B solely with message-passing)? |

The last supercomputers running lightweight kernels are the remaining IBM [[Blue Gene|Bluegene]] systems running [[CNK operating system|CNK]]. A new direction for lightweight kernels is to combine them with a
full-featured OS, such as Linux, on a many-core node. These
omitted in lightweight kernels. By combining the two, users get the Linux features they need but also the deterministic behavior and scalability of lightweight kernels.
