Summary

NrOS is an operating-system kernel that scales a mostly sequential kernel design across NUMA machines using node replication. It keeps per-NUMA-node replicas of kernel state, lets cores read locally, and uses operation logs to keep replicas consistent while retaining much of the simplicity of a sequential kernel.
