  • Early coverage of process containers
  • Paul Menage's 2007 paper "Adding Generic Process Containers to the Linux Kernel"
  • Dawn's first job: tracking processes. Each job had its own GID - she would use netlink connection tracking to map processes and threads to GIDs, and, using procfs, figure out CPU and memory usage.
  • Dawn's second job: adjusting CPU usage using nice
  • Today we just use memcg
  • Fake NUMA - cut a machine into big chunks and assign them to groups of processes.
• Linux Plumbers Conference
  • Tim Hockin's presentation at the Linux Plumbers Conference in 2011, talking about the work Dawn's team were doing
