Table Explanation

• Software: The name of the application that is described
• SMP aware:
  • basic: hard split into multiple virtual host
  • basic+: hard split into multiple virtual host with some minimal/incomplete communication between virtual host on the same computer
  • dynamic: split the resource of the computer (CPU/Ram) on demand
